Azure storage blob event trigger with filter in logic app

 

There might be a scenario where you want to filter out your event trigger based on some condition. I am going to take simple scenario and also using our existing logic app that I created in last blog.

 

Scenario: 

When you have multiple blob storage but want to trigger an event only from one container. This won’t impact any other container.

  

Open the existing logic app “event-based-logic-app” created in last blog.

 

 

Click on “Add new parameter” and choose “prefix filter”

 

 

Provide “/blobServices/default/containers/<container_name>/blobs” parameter

 

 

Save your logic app and try uploading a file in “toprocess” container. You can see the logic app has been triggered but if you upload file in any other container, it won’t trigger.
