I have followed the auth document step by step but I still get this error.

The first step is all good. I can get the code from the response
But when trying to get the access_token, I always received 'invalid_client'

Here are the request details:

It's a local env with client id and secret. The callback url is: http://localhost

Client id is: 665df5df-0588-4ee8-8add-0a156576e8bc
Client secret: c12bbb8a-2443-4acb-96ec-83aa22fc421f
HttpType: POST
{'Content-Type': 'application/x-www-form-urlencoded', 'Authorization': 'Basic NjY1ZGY1ZGYtMDU4OC00ZWU4LThhZGQtMGExNTY1NzZlOGJjOmMxMmJiYjhhLTI0NDMtNGFjYi05NmVjLTgzYWEyMmZjNDIxZg=='}

{'code': '9aff562a59207c6cc2fb21b24875b252',
'redirect_uri': 'http://localhost', 'grant_type': 'authorization_code'}

<Response [400]>
{"error":"invalid_client"} Please help me with this issue ASAP. We have been stuck by this problem for ages.

Hi there,

Based on what I know, it could be the callback URL you registered with this client id is not localhost, but it could be something else as well.
You should contact so they can see what is the real issue.
