Hi @Dev_SAVIT,

If you’re using an OAuth access\_token, this expires after one hour. You will need to refresh your token following the steps outlined here:

Hey @Dev_SAVIT,

Thanks for the reply—a few things to check:

- Confirm that you’re using the refresh\_token that was returned in the same payload as the original access\_token
- Double check that your Authorization header includes the base64encoded Client ID:Client Secret for the correct version of your app (prod or dev)

Let me know if either of these items help!  
Will
