Client Credential Grant not supported

  1. Hey there,

    I am a developer and i am trying to use the client credential flow, but the response is 400 with unsupported grant_type. Please contact me and lets fix this issue, because it's blocking us from continuing. Thank you!

    Given what you've provided, we can only speculate on the issue:

    • You may be trying to put your client credentials in the URL (as opposed to the body)
    • Or, assuming you are POSTing the credentials in the body, you might be using JSON (application/json) instead of application/x-www-form-urlencoded.

    If we're wrong here, can you provide more information about the request that's failing? If possible, a CURL call with your credentials XXX'd out would be great.
