I'm making a request to https://api.thomsonreuters.com/gosystem/oauth2/v1/auth-code to authenticate to GoSystem and getting back an error 400 with the following response:
{"type":""title":"Invalid">developers.onesourcetax.com/.../ Input - Error getting user JWT - 400 received from service.","detail":"Invalid Input - Error getting user JWT - 400 received from service. Unable to fetch user JWT: Error verifying user","error_code":" Unable to fetch user JWT: Error verifying user","status":400,"instance":"/gosystem/oauth2/v1/auth-code","api_requestId":"rrt-04d5693dd5af70943-b-ea-6960-54208821-11"}
What could be causing this?
Thanks.
