I have quite the same problem... I configured the serviceId according to documentation, registered the return urls I use as redirecturi in the authorize url, check all parameters (like clientid) are correct. But I keep getting the very same error: "invalid_request Invalid web redirect url." Any one who felt into this with any suggestions? Thanx P.S. = I already post an issue to Feedback assistant

Hi furick1, we have a similar problem... Did you solve the issue in the end?

We solved.. in the end we discovered a typo in the return url we set up in the ServiceId configuration

Hi, did you solve the issue? I'm getting the same problem... when validating a refreshtoken I get a tokenResponse with accesstoken and without refreshtoken. It seems reasonable except when I try to validate again the same refreshtoken I receive an "invalid_grant" error
