Begineer in Logic apps

Question

I have a Logic app which is getting triggered successfully on trigger action 'when a blob is created or updated'.

I would like the logic app to be triggered only for the blobs which are newly created and not for all blobs? so If i have blob A.txt, blob B.csv coming in my blob storage, my logic app actions should only be for A.txt and B.csv and not the existing blobs. I saw option is to use Event grid with logic app and I tried it but I am unable to get the blobs.

from Resource events , this is the response i get:

my design looks like this

Please guide on how can i get only the new blobs which are added and do the necessary action with them

Thanks

Hello @ankit kumar , The trigger used by you "When resource event occurs" with event "Microsoft.Storage.BlobCreated" should trigger your logic app when a Blob is uploaded in the linked storage account. The trigger successfully executed for me when I uploaded the Blobs in the container or within any sub-folder, as shown below.

Sub-Folder

Parent directory

Please let me know if you need any additional help.
