Start power automate on new or modified document only when a condition is met

Starting a Power Automate flow on a new or changed document or item is easy. But can you only start it when a certain condition is met? 

Yes, you can.

In this example I only want to start the flow when the field “Document Status” is set to “To review”.

Here’s how.

The trigger for this flow is: When a file is created or modified

We need to go to the settings of this action…

Add a trigger condition…

@equals(triggerOutputs()?[‘body/Document_x0020_Status/Value’], ‘To review’)

Click Done and now the flow will only start if the condition is met.

Bonus tip!

If you find it hard to create the trigger condition expression do this:

Select the expression and copy it into the trigger action from above.

After this you can delete the Do until action.
