Whenever the Agent or Admin opened the particular ticket the following error is popping up “You are not authorized to perform this action”, We are using full admin access API Key for Integration. We changed the roles and checked it but same issue occurs.
It is more priority for us, so please give us the solution as soon as possible.
Without understanding what the app is trying to do, and what access the API key has, it would be difficult for anyone to propose a solution to this. More likely than not, the 403 tells one that the API key does not have the authorization to do what the app needs to do in this case.
