Power Automate Trigger Conditions [33 Useful Examples]

In this Power Automate tutorial, users will get to know all about how to use trigger conditions in Power Automate. Also, we will see various examples of power automate trigger conditions:

• Power Automate trigger condition
• Power Automate adds trigger condition
• Power Automate trigger condition with examples
• Power Automate trigger conditions equals
• Power Automate trigger condition not equal
• Power Automate trigger condition contains
• Power Automate trigger condition not empty
• Power Automate trigger conditions multiple
• Power Automate trigger condition SharePoint column
• Power Automate trigger condition And OR
• Power Automate trigger condition AND
• Power Automate trigger condition OR
• Power Automate trigger condition email subject
• Power Automate trigger condition email
• Power Automate trigger condition empty
• Power Automate trigger condition greater than
• Power Automate trigger condition true false

• Power Automate trigger condition approval status
• Power Automate trigger condition lookup field
• Power Automate trigger condition based on time
• Power Automate trigger condition string
• Power Automate trigger condition has attachment
• Power Automate trigger condition infinite loop
• Power Automate trigger condition team

As the name suggests, a ‘Trigger condition’ is a condition that will trigger the flow as per the specified condition. Usually, we use a trigger condition to stop the infinite loop.

For example, we have created a flow that will trigger when an item is created or modified in the SharePoint list. We can see the flow will start with every update that will consume more space, to restrict that we need to set a trigger condition.

Power Automate trigger condition

In Power Automate, the trigger condition is specified b the expression that evaluates the output in boolean format i.e. true or false.

The trigger condition allows one or more expressions using logical operators that must be true for the trigger to fire. Before using the trigger conditions, we need to sign in the Power Automate with the Microsoft user ID or your office ID.

As the dynamic content menu is not available so the user must use the expression using the available functions that return a boolean value. The trigger condition does not allow the numeric or object type, if we set the trigger condition using a non-null value then the flow will fail to tun,

The following table shows us whether the condition expression is valid or not.

Expression	OutPut (Data type)	Valid?
@add (15,10)	Integer	No
@json(triggerBody())	Object	No
@equals(5,5)	Boolean	Yes
@true	Boolean	Yes

Power Automate add trigger condition

We can add one or more trigger conditions using ‘AND‘ & ‘OR‘ operators that evaluate a ‘true‘ value in Power Automate or Microsoft flow.

To add the trigger condition option, the following steps are:

• On Power Automate, create an automated flow or any kind of flow by selecting a trigger. For example, let us create an instant cloud flow and select the trigger ‘Manually trigger a flow‘, and click on create.

• In the trigger, click on the ellipses (…) (in the upper right corner) > settings.

• Click on setting. We can find the option to add the trigger condition at the bottom with other properties such as:
  • Custom Tracking Id – The trigger’s Custom Tracking Id provides for the static or dynamic input of an identifier that may be passed in or set from the trigger and then added to the response.
  • Secure Inputs/Outputs – It is used to handle sensitive data such as passwords, IDs, banking-related information, etc.
  • Concurrency Control – It is used to control the concurrent or parallel run of our flow.

Note – Make sure to add a ‘@’ symbol at the beginning of the trigger condition.

Power Automate trigger condition with examples

Here we will see how the trigger condition works within the Power Automate with an example.

Suppose we have a SharePoint list based on ‘Products’ having columns such as:

Columns	Data type
Title	Default
Vendor	Single line of text
Types	Choice
Price	Currency ($)
OrderDate	Date and Time
Status	Choice

Now, we will create a flow that will send a notification when an item is created or modified in the SharePoint list and if the vendor is equal to ‘Dell’ then it notify a specified user or HR via Outlook.

To create the flow the following steps are:

• On Power Automate, create an automated flow that will trigger when an item is created or modified. Click on +Create > Automated Cloud Flow > When an item is created or modified > Create. Provide the SharePoint site address and the list name.

• Next, add an action that will send an email notification to the specified user. Click on +New step > send an email. Set the properties such as:
  • To – Specify the person’s email to whom you want to send the notification
  • Subject – Specify the email’s subject
  • Body – Specify the body of the email using dynamic content.

• Now, we will add the trigger condition that will trigger only when the vendor is equal to Dell. To add the condition, go to the setting on the trigger and add the below expression:

@equals(triggerBody()?['Vendor'], 'Dell')

Click on the Done. Now save the flow and test it. For testing, add a new item in the SharePoint list with the vendor ‘Dell’.

We can see it will send an email notification to the specified user.

Similarly, the flow will trigger when an item is modified to ‘Dell‘ and send an email notification to the specified user. This is how the trigger condition works on Power Automate.

Power Automate trigger condition contains

In this example, we will see how to use contains function in the Power Autonare trigger condition.

We have a SharePoint task list based on tasks, descriptions, assignees, start date, and status. Now, we will set a condition that will trigger the flow if the title contains ‘Power Automate’.

@contains(triggerBody()?['Title'], 'Power Automate')

As per the condition, the flow will trigger only when the title of the task list contains the specified text i.e. ‘Power Automate’; otherwise, the flow will not trigger.

This is how to do Power Automate trigger condition using contains.

Read Power Automate email body formatting

Power Automate trigger condition not equal

Similarly, in this example, we will see how to use the ‘not equal’ function in the Power Automate trigger condition.

Let us take the previous SharePoint task list example where the flow will trigger when the title is not equal to ‘Power Automate’. In that case, we will insert the below expression in the trigger condition section.

@not(equals(triggerBody()?['Title'], 'Power Automate'))

The flow will trigger only when the title is not equal to Power Automate; otherwise, the flow will not run. This is how the ‘not equals’ function works with the Power Automate trigger condition.

Power Automate trigger condition equals

In this example, we will see how to work with the equals function in the Power Automate trigger condition.

Suppose we have a SharePoint list based on Vehicles with some random data.

Now we will create a flow and set a trigger condition that will trigger the flow if the country is equal to the USA.

• On Power Automate, we will create a flow that will trigger when an item is created or modified in the SharePoint list. Click on +Create > Automated Cloud Flow > When an item is created or modified > Create. Provide the SharePoint site address and the list name.

Here they will trigger and proceed with the further steps (as per your requirement) when the country is equal to the USA; otherwise, the flow will not run.

This is how to use trigger conditions with equals function in Power Automate.

Power Automate trigger condition AND

In Power Automate we can add multiple trigger conditions using ‘AND’ and ‘OR’ operators. In this example, we will see how to use the AND operator in the Power Automate trigger condition. To implement this, we are going to take the previous SharePoint list (i.e. Vehicles).

Suppose we will create a flow that will trigger when the title and the country are equal to the specified values such as Tesla and UK respectively.

The syntax for the AND operator:

@and(condition1, condition2, condition3,...)

To implement this, first, we will trigger the flow when an item is created or modified in the list. Then provide the SharePoint site address and the list name. Then go to the trigger condition and set the below condition:

@and(equals(triggerBody()?['Country'], 'USA'), equals(triggerBody()?['Title'],'Tesla'))

Here the flow will trigger when both conditions are satisfied; else, the flow will stop running. This is how to add trigger conditions using AND operator in Power Automate.

Power Automate trigger condition OR

Similarly, we can use the ‘OR’ operator instead of the ‘AND’ operator in the trigger condition. Here, if one of the condition is true, then the whole statement execute a true value. The syntax for the OR operator is:

@or(condition1, condition2, condition3,...)

To implement this, we are going to use the previous example where the flow will trigger only when the title or the country is equal to the specified values.

Suppose the flow will trigger only when the title is equal to ‘Tesla’ or the country is equal to ‘USA’. For this the expression will be:

@or(equals(triggerBody()?['Country'], 'USA'), equals(triggerBody()?['Title'],'Tesla'))

Then click on Done. Add the action as per your requirement. We can see the flow will trigger if one condition got true. This is how to use the OR operator in the Power Automate trigger condition.

Power Automate trigger condition AND OR

In this example, we will see how to use both the ‘AND’ and ‘OR’ operators in the trigger condition.

• Suppose, we will create a flow and set a trigger condition that will trigger when the country and the state are equal to ‘USA‘ and ‘Texas‘ respectively or the title equals ‘Tesla‘.
• For this, we will create a flow that will trigger when an item is created or modified in the SharePoint list. Provide the SharePoint site address and the list name.
• Insert the below expression in the trigger condition section:

@or(and(equals(triggerBody()?['Country'],'USA'), equals(triggerBody()?['State'],'Texas')),equals(triggerBody()?['Title'],'Tesla'))

According to the above expression, the flow will trigger only when an item is created or modified, and also, when their country and the state or the title will match the given values. This is how to use the AND & OR operator in the Power Automate trigger condition.

Power Automate trigger condition greater than

Here, we will see how to use the ‘greater than’ function in Power Automate trigger conditions. To implement this, we are going to use the previous SharePoint list i.e. Voters list.

Suppose, when we modified or created an item (voter’s name and age) in the SharePoint list, the flow will trigger as per the trigger condition i.e. the flow will trigger only when the voter’s age is greater than or equal to 18.

To create the flow, the following steps are:

• On Power Automate, click on + Create > Automated Cloud Flow > When an item is created or Modified > Create.
• Specify the SharePoint site address and the list name.
• On the trigger, go to the trigger condition and set the below expression:

@greaterOrEquals(triggerBody()?['Age'],18)

As per the above expression, the flow will trigger only when the age is greater than or equal to 18.

• Next, add a compose action to view the result:

Now, save the flow and test the flow manually. For testing purposes, let us create a new item or modify an item:

We can see the flow will run when the age is greater than or equal to 18.

This is how to do Power Automate trigger condition using greater than.

Read Power Automate dynamic content

Power Automate trigger condition less than

Similarly, here, we will see how to use the ‘less than’ function in the Power Automate trigger condition.

Now, we will create a flow that will fire when the trigger condition matches i.e. if the age is less than 18. In this case, the expression will be:

@less(triggerBody()?['Age'],18)

As per the above expression, the flow will trigger when an item is created or modified and the value is less than 18; otherwise, the flow will not trigger. This is how to do the Power Automate trigger condition using less than.

Power Automate trigger condition email

In this example, we will see how to insert a trigger condition when an email arrives in your mailbox (i.e. outlook) using Power Automate.

Now, we will create a flow that will trigger when an email comes from a specific person and it will notify the user via Microsoft Teams. To create the flow, the following steps are:

• On Power Automate, click on +Create > Automated Cloud Flow > When a new email arrives > Create. Select the folder location to check the new emails (i.e. Inbox).
• On the trigger, click on the ellipses(…) > setting > Trigger condition. Insert the below expression.
• Click on Done.

@equals(triggerBody()?['From'], 'User3@tsinfotechnologies.com')

The above expression shows that the flow will run only when the email comes from the specified user; Otherwise, the flow will not run.

• Next, we will add another action ‘Post message in a chat or channel‘ that will notify the user via Microsoft teams when the email arrives. Set the properties such as:
  • Post as– Flow bot
  • Post in– Chat with flow bot
  • Recipient– specify with a user email
  • Message– Give a message that will appear on the Teams

Let’s save the flow and test it manually. Send an email from the specified user ID to yourself for testing purposes.

We can see it will notify the user via teams like below:

This is how to set Trigger Conditions When a new email arrives (v3) using Power Automate.

Read Power Automate shared mailbox

Power Automate trigger condition email subject

Similarly, here, we will see how to insert a trigger condition based on the email’s subject using Power Automate.

For example, we will create a flow that will trigger when the email subject contains a specific message. To create the flow, the following steps are:

• On Power Automate, click on +Create > Automated Cloud Flow > When a new email arrives (V3) > Create.
• In the trigger, click in the ellipses (…) > settings > Trigger conditions.

@contains(triggerBody()?['subject'], 'Offer Letter')

• Next, add an action ‘Post message in a chat or channel‘ and set the properties to activate the action.

Now save the flow. For testing purposes send an email from another user to yourself where the subject has that specific keyword.

We can see the flow will run successfully if the email subject has the specific word otherwise the flow will not trigger. This is how to do the Power Automate trigger condition using the email subject.

Read Power Automate flow with Microsoft teams

Power Automate trigger condition empty

Here we will see how to use the empty function in the Power Automate trigger condition and based on that the flow will trigger only when a specific field is empty in a SharePoint list or library.

For example, when we upload a file in the SharePoint library, the flow will trigger and check if the ‘details‘ field is empty in that library then it will notify the user about the empty field.

Suppose we have a library like the below:

To create the flow, the following steps are:

• On Power Automate, click on My flows > +New flow > Automated Cloud Flow > Create.
• Specify the SharePoint site address and the library name.
• Then click on the ellipses(…) of the trigger > Settings.

• Set the below expression in the trigger conditions section.

@empty(triggerBody()?['Details'])

• Next, add an action ‘Post message in a chat or channel‘ and set the properties to activate the action.

Now we will save the flow and test it manually. Let us upload a file in that library without details.

We can see it will notify the specified user about the empty field via Teams like below:

This is how to use the Trigger condition when the field is empty in Power Automate.

Read Power Automate vs Nintex

Power Automate trigger condition not empty

Similarly, we can trigger the flow if the field is not empty. For this, we need to insert the below expression in the trigger condition.

@not(empty(triggerBody()?['Details']))

Here, the flow will trigger if the details field is not empty; otherwise, the flow will not trigger. This is how to do the Power Automate trigger condition not empty.

Power Automate trigger condition true false

In this example, we will see how to use the true/false statement in Power Automate. For example, we have a ‘yes/no’ column in the Voters SharePoint list (we have used it previously).

Now we will create a flow that will trigger if the voter is eligible for voting as per the respective age. To create the flow,

• On Power Automate, create an automated cloud flow and trigger this ‘When an item is created or modified. Provide the SharePoint site address and the list name.
• On the trigger, click on the ellipses (…) and then go to setting. In the trigger condition, insert the below expression.

@equals(triggerBody()?['Eligible'],true)

• Click on Done.
• To see the output, add a compose action under the trigger and add the dynamic contents.

Now save the flow and test it. For testing purposes, let us modify one data in the list and mark it as eligible.

We can see as the trigger conditions matched true, so the outcome will appear like below:

The flow will trigger only when the true/false or yes/no column mark as true; otherwise, the flow will not start. This is how to use the Power Automate trigger condition with Boolean.

Read Power Automate or Microsoft Flow delete all files in a folder

Power Automate trigger conditions multiple

Now, we will see how to use multiple trigger conditions on Power Automate. For example, we have a SharePoint list based on task, their respective assignees, and the details such as:

Based on the above list, we are going to create a flow that will trigger only when the title contains a specified text i.e. ‘Power BI’ and the status is equal to ‘Completed’. To create the flow, the following steps are:

• On Power Automate, create an automated flow that will trigger when an item is created or modified. Provide the SharePoint site address and the list name.
• On that trigger, go to the setting > trigger conditions. Insert the below expression to check whether the title contains ‘Power BI’ or not.

@contains(triggerBody()?['Title'],'Power BI')

• To add another condition, click on the +Add, then add the below expression to check whether the status is completed or not.

@equals(triggerBody()?['Status']?['Value'], 'Completed')

• Click on the Done. Now add a compose action and insert some fields from the dynamic contents such as title, status, date, etc.

Let’s save the flow and test it, For testing purposes, we will modify one data according to trigger conditions:

We can see as the conditions got matched, the flow will trigger and the output will come as:

This is how to use multiple trigger conditions in a flow.

Power Automate trigger condition SharePoint column

Here, we will see how to use the SharePoint column in the Power Automate trigger condition. Suppose, we have a SharePoint list based on task reports having some random data.

Now, we will create a flow that will trigger if the created or modified item contains a specified text (i.e. ‘SharePoint’) then it will notify the respective employee via outlook. To create the flow, the following steps are:

• On Power Automate, create an automated cloud flow and trigger the flow when an item is created or modified in the SharePoint list. Provide the SharePoint site address and the list name.
• Then on the trigger conditions set the below expression that will trigger the flow if the ‘topic name‘ has SharePoint.

@contains(triggerBody()?['Topicname'], 'SharePoint')

• Click on Done.
• Add another action to send an email to the respective assignee to notify them about the task. Click on +New step > Send an email. Set the properties such as To, Subject, and Body.

Now save the flow and test it. For testing purposes, let’s modify an item in that list where the topic name contains ‘SharePoint‘.

As the topic name contains the specified text, the flow will trigger and send the notification to the assignee like below:

If the topic name does not contain the specified text, then it will not trigger. This is how to use the SharePoint column in the Power Automate trigger condition.

Read Power Automate add days to date

Power Automate trigger condition modified date

In this example, we will see how to modified date and time works in the Power Automate trigger condition.

Let us take an example of a Sharepoint list based on Products and their details such as:

Now we will create a flow, that will fire when both the created and the modified timings are the same. To create the flow, the following steps are:

• On Power Automate, create an automated flow and trigger it when an item is created or modified. Provide the SharePoint site address and the list name.
• Then on the trigger, set the below expression in the trigger conditions:

@equals(triggerBody()?['Modified'], triggerBody()?['Created'])

• To see the output, we will add a compose action with some dynamic contents.

Now save the flow and test it manually. Let us create a new item in the SharePoint list to test the flow.

As both the created and the modified are at the same time, the flow will trigger successfully. This is how to trigger the condition modified date on Power Automate.

Read Power Automate Increment Variable

Power Automate trigger condition null

Here, we will see how to work with a null value in the Power Automate trigger condition. To implement this, we are going to use the previous SharePoint list (i.e. Product) where the Status has a null value like below:

Now we will create a flow that will trigger when the status has not a null value. For this, we will create an automated cloud flow and trigger it when the item is created or modified and insert the below expression to fire the flow if there is no null value in the status field.

@not(equals(triggerBody()?['Status']?['Value'], null))

• Add a compose action to see the outputs:

Now save the flow and for testing purposes, let us modify the status in the SharePoint list.

As the status has no value the flow will trigger successfully and the output will come as:

This is how to use the null value in the Power Automate trigger condition.

Power Automate trigger condition ends with

In this example, we will see how to use the ‘ends with’ function in the Power Automate trigger condition. Here, we are going to use the previous SharePoint list i.e. Product.

Now, we will create an automated flow that will fire when the item is created or modified and ends with a specific text. Suppose, the flow will be triggered when the product’s title ends with ‘top’ (whether it is a laptop or desktop); otherwise the flow will not trigger and run.

• Create an automated flow that will trigger when an item is created or modified. Then provide the SharePoint site address and the list name.
• In the trigger condition section, add the below expression:

@endswith(triggerBody()?['Title'], 'top')

• Then add other logical actions as per the requirements. For example, we are going to use the compose action with some values having dynamic contents to show the output.

Now save the flow and test it. For testing purposes, modify an item to another that endswith ‘top’ i.e. Desktop.

As the modified item ends with ‘top’, the flow will be triggered successfully and return the output. This is how to use the ‘ends with’ function in the Power Automate trigger condition.

Power Automate trigger condition choice column

In this example, we will see how to work with the choice column or option value in the Power Automate trigger condition.

To implement this, we are going to use the previous SharePoint list i.e. Product. Now, we will set trigger conditions that will trigger the flow when the status is Delivered.

@equals(triggerBody()?['Status']?['Value'], 'Delivered') 

Click on Done. We can see the flow will trigger when the status is updated to deliver. This is how to do the Power Automate trigger condition choice column.

Power Automate when an item is created trigger condition

In this example, we will see how to use a trigger condition when an item is created in the SharePoint list.

Suppose, when a task is created in a SharePoint list having a specified text and the task is assigned to you, then it will create a task in the Microsoft Planner automatically.

The list that we have prepared looks like the below:

Now, we will create a flow that will trigger when an item is created based on ‘Power Automate’ and assigned to a specific person ‘Sonam Subhadarsini’ then it will create a task in the user’s planner.

To do this, the following steps are:

• On Power Automate, create an automated flow that will trigger when an item is created in the SharePoint list. Provide the SharePoint list and site address.
• Then in the trigger conditions section, insert the below conditions:

Note- You can merge the conditions with the AND operator or insert them separately.

@contains(triggerBody()?['Title'],'Power Automate')

@equals(triggerBody()?['AssignedTo']?['DisplayName'], 'Sonam Subhadarsini')

• Next, add an action ‘Create a task‘ to create a task in the Microsoft Planner. Provide the Group Id, Plan Id, Title, Bucket Id, Assigned user Ids, etc.

Now, the flow is ready. Let’s save the flow and test it manually. Create a new item in the SharePoint list as per the conditions set:

We can see as both the conditions matched, a task has been created in the planner:

This is how to set trigger conditions in Power Automate when an item is created.

Power Automate trigger condition modified by

Here, we will see how to set a trigger condition when an item is modified by someone else. Let’s take the previous task list as an example where the flow will trigger if the created and the modified fields are not the same.

To create the flow, the following steps are:

• On Power Automate, create an automated flow that will trigger when an item is created or modified. Specify the SharePoint site address and the list name.
• Then go to the trigger conditions section, and insert the below expression:

@not(equals(triggerBody()?['Author']?['DisplayName'], triggerBody()?['Editor']?['DisplayName']))

Note- Here the ‘Author‘ and ‘Editor‘ are the internal names of the ‘Created by‘ and ‘Modified by‘.

• Add another action ‘Post message in a chat or channel‘ and set the properties such as Post as, post in, Recipient, Message (using dynamic contents).

Now the flow is ready. To test the flow, let’s modify an item from another user:

As both the author and editor are not the same, it will notify the specified user about the modification via Microsoft Teams. This is how to do Power Automate using trigger conditions based on Modified by.

Power Automate when a file is created trigger condition

Here, we will see how to use the trigger condition when a file is created in a SharePoint document library.

Suppose, there is a document library ‘File Storage‘ on the SharePoint site. Now, we will create a flow that will trigger when a file is created and we will set a trigger condition on that flow i.e. the flow will trigger only when the file contains a specific text. Also, it will notify the given user about file uploading.

To create the flow, the following steps are:

• On Power Automate, create an automated cloud flow that will trigger the flow when a file is created. Specify the SharePoint site address and the library name.
• To set the trigger condition, click on ellipses (…) > Settings.

• On the trigger condition, set the below expression that will fire the flow only when the file name contains the text ‘Power Automate’.

@contains(triggerOutputs()?['body/{FilenameWithExtension}'], 'Power Automate')

• Add a ‘Post message in a chat or channel‘ to notify the user about the related file (set the properties as previously).

Now, save the flow. To test the flow, upload a file in the document library:

As the file name contains ‘Power Automate’, the flow will trigger successfully and notify the user via Teams like below:

Note – The flow will not trigger and run if the file does not contain the given text i.e. Power Automate.

This is how to set trigger conditions when a file is created in a library in Power Automate.

Power Automate trigger condition file name

Here, we will see how to use a trigger condition based on a file name. For example, we can trigger a flow if the filename contains the specified extension i.e., .pdf, .txt, .xlsx, etc.

In such a case the trigger condition will be:

@endswith(triggerOutputs()?['body/{FilenameWithExtension}'], '.pdf')

Similarly, we will add a ‘Post message in a chat or channel‘ to notify the user about the file uploading.

Now save the flow and test it. Let’s upload multiple files including pdf format.

We can see it will notify only about that file whose filename contains ‘.pdf’. This is how to do the Power Automate trigger condition based on the file name.

Power Automate when a new email arrives trigger condition

Here, we will see how to set a trigger condition when a new email arrives in your mailbox i.e. Outlook.

For example, we will create a flow that will trigger when a new email arrives from a specific person and it will send a mobile notification to the user; otherwise, the flow will not trigger. To implement this, we will create a flow and the following steps are:

• On Power Automate, create an automated cloud flow and trigger it ‘When a new email arrives and select the ‘Inbox‘ as the email folder.
• Set the below expression on trigger condition that will trigger only when the email comes from a specified user i.e. ‘User3@tsinfotechnologies.com‘.

@equals(triggerBody()?['From'], 'User3@tsinfotechnologies.com')

• Add an action ‘Send me a mobile notification‘ that will notify the user via mobile.

Now save the flow. Send an email from the specified user ID.

As the condition is satisfied, so it will trigger the flow successfully and notify the user via mobile like below:

This is how to set trigger conditions when a new email arrives on Power Automate.

Power Automate trigger condition approval status

In this example, we will see how to use the trigger condition based on approval status in Power Automate.

For example, we have a SharePoint list of ‘Office expenses’ where the employee will request the office expenses. Based on the list, we will create a flow that will trigger only when the approval status will be updated as ‘Delivered’ and notify that user via the teams who created that request.

To create the flow, the following steps are:

• On Power Automate, create an automated flow that will trigger when an item is created or modified in the SharePoint list. Set the trigger condition using the below expression that will trigger only when the approval status will be set as ‘Delivered’.

@equals(triggerBody()?['Status']?['Value'], 'Approved')

• To send the approval notification via the teams, add an action ‘Post message in a chat or channel‘. Set the properties as previously.

Now the flow is ready. To test the flow, let’s update the approval status to ‘Delivered’ in the SharePoint list.

As the approval status changes, it will send a notification to the requestor who created this request via the teams below:

This is how to use Power Automate trigger conditions based on approval status.

Power Automate trigger condition lookup field

Now, we will see how to use lookup field in Power Automate trigger condition. For example, we have a SharePoint list based on Events with some columns including a look up column i.e. Organizer.

Now we will create an automated flow that will trigger when an item is created or modified. Also, the flow will trigger only based on a trigger condition. As per the condition, if the lookup field is empty then it will notify the user via the Microsoft teams.

To create the flow, the following steps are:

• On Power Automate, create an automated cloud flow and trigger it when an item is created or modified.
• Set the below expression in the trigger condition that will fire the flow if the lookup field is empty.

@empty(triggerBody()?['Organizer'])

Next, add a ‘Post message in a chat or channel‘ and fill all the properties to activate the action.

Now save the flow and test it. For testing purposes, let’s insert a data in the SharePoint list:

We can see as the lookup field is blank, so the flow will triggered and send a notification via the teams who created this record.

This is how to work with lookup field in Power Automate trigger condition.

Power Automate trigger condition based on time

Here we will see how to work with trigger condition based on times. We have a SharePoint list having two date and time columns:

Now we will create a flow that will trigger when an item is created or modified and both the time are not same. In such case the trigger condition will be:

@not(equals(triggerBody()?['OrderDateTime'], triggerBody()?['ShippedDateTime']))

By using the above trigger condition, the flow will only when the created item or modified item has different date times ; otherwise, the flow will not trigger. This is how to use trigger condition based on time in Power Automate.

Power Automate trigger condition string

Similarly, here we will see how to use string data type in Power Automate trigger condition. For example, we have a SharePoint list that contains student’s name along with their last name, and their results.

Now we will create a flow that trigger when an item is created or modified in the SharePoint list. Also, insert the below trigger condition:

@empty(triggerBody()?['LastName'])

As per the above trigger condition, the flow will be trigger only when the created or modified item has blank string data i.e. blank lastname. This is how to use string data type in Power Automate trigger condition.

Power Automate trigger condition teams

This example will show how to set a trigger condition based on the Microsoft teams. For example, when an important message will post on a channel it will notify the user via mobile notification.

To implement this, we will create an automated flow and the following steps are:

• On Power Automate, create an automated cloud flow and trigger it ‘When a new channel message is added‘. Provide the team and the channel.

• To set the trigger condition, click on the ellipses(…) > settings > trigger condition. Insert the below expression that will trigger when an important or high-importance message is posted on the teams.

@equals(triggerOutputs()?['body/importance'], 'high')

• To send the notification via mobile, add another action ‘Send me a mobile notification‘. Set the text field using the dynamic contents. We can see what the flow will look like below:

Now the flow is ready to run. To test the flow, let’s post a message in the specified channel and make it as important:

We can see as it is an important message it will send a notification to the user via mobile like below:

Power Automate trigger condition has attachment

In this example, we will see how to set a condition on the trigger when an item is created in the SharePoint list.

As per the trigger condition, the flow will trigger the created item that has attachments in the SharePoint list.

To create the flow, the following steps are:

• On Power Automate, create an automated cloud flow that triggers when an item is created in a specified SharePoint list. Provide the SharePoint site address and the list name.
• On the trigger, go to the trigger conditions and set the below expression:

@equals(triggerOutputs()['body/{HasAttachments}'], bool('True'))

• To see the result add a Compose action and add values like the below:

Now save the flow and test it. Let’s insert an item with an attachment in the Sharepoint list.

As the item has an attachment, the flow run successfully and the output will come like this:

This is how to use the Microsoft flow trigger condition has an attachment.

Power Automate trigger condition infinite loop

Here we will see how to avoid an infinite loop in the Power Automate trigger condition. For example, we are going to use a SharePoint list, when we created or modified an item it will update the item by adding some random digit to it.

To update the item automatically, we have created an automated flow like the below:

In the compose action, we used the below expression:

concat('',rand(1,9))

In the Title, we inserted the below expression:

concat ( triggerOutputs()?['body/Title'], outputs('Compose'))

When we save the flow, we can see a warning message in the flow checker.

Actions in this flow may result in an infinite trigger loop. Please ensure you add appropriate conditional checks to prevent this flow from triggering itself.

When we run this flow, we can see it will create an infinite loop.

To avoid this, we will insert a trigger condition. As per the trigger condition, if the title equals a specified text, then the infinite loop will stop and update the item.

@equals(triggerBody()?['Title'], 'Checklist1')

Now save the flow and test it. We can see the flow will stop the infinite loop. This is how to avoid an infinite loop in the Power Automate trigger condition.
