Source: https://tickwire.io/docs/errors/request_not_supported/

HTTP 400.

**Likely cause:** The authorization request carried a request or request_uri parameter.

**What to do:** Send the authorization parameters in the query string.

**Retry:** No. The same request gets the same answer; change something first.
