Hello everyone, I'm having a problem trying to create an envelope.
Getting the error:
Error while requesting server, received a non successful HTTP code [401] with response Body: O:8:"stdClass":2:{s:9:"errorCode";s:27:"AUTHORIZATION_INVALID_TOKEN";s:7:" message";s:105:"The access token provided is expired, revoked or malformed. Authentication for System Application failed.";}.
All credentials are properly set. Is there any extra configuration to be done with the token received through OAuth?
