Trigger flow on blob added, but not on blob modified

(1) ShareShare

Posted on by

I am using the "When a blob is added or modified (properties only) (V2)" Azure Blob Storage trigger. Is there a way to trigger a flow only when a blob is added and not if it is modified? E.g. Is there a property I can check in a trigger condition, or later in a condition statement, to see if the item was modified or created?

 

In Azure Storage browser you can see that a blob was modified when its 'Creation time' property is different from its 'Last modified' property. In Power Automate, I can see there is a LastModified date property on the trigger body, but there does not seem to be one for Created date.

 

The answer: Re: When file is added to Azure Blob storage trigg... - Power Platform Community (microsoft.com), suggests this may be possible using Event Grid, but we do not currently use that service and would rather not set it up just for this purpose.

 

Many thanks.
