Hi All,


I had a REST API integration working on both my Dev instance and client's Enterprise one until today. Client is complaining that it stopped working for them. I've checked both instances and they both have the same issue: when trying to refresh token I'm getting:


{"error":"invalid_client_id","error_description":"client identifier invalid"} 


None of the code changed since it was confirmed working and definately the Client ID / Consumer Key did not change.


Any idea anyone?

Any thoughts or suggestions will be appreciated.
