i have generated the clientID and Client Secret followed by the GoToMeeting API documentation and using those clientID and client secret in encodeBase64 i have generated the bearer token. Then using the ClientID and redirect URL i got code. by providing the code and bearer token i have generated the access token.
now i have given the access token and the body followed by the documentation but im getting an error like "Some mandatory attributes are missing ". But i have provided the proper body as per you detailed in the documentation. For you reference i have attached my screenshot.
