Hey Lucas,

It’s hard to say exactly what is causing your problem but off the top of my head here are a couple of things to check.
When making your Auth request with the URI initially you need to make sure that URI you are providing is URL encoded especially if you have additional parameters. Second I would make sure that your /token request is using the same URI as used in the initial Auth request.
If neither of these things help in resolving your issues please provide us with both the /authorization and /token request with the full URI information. So we may review it.
