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]>  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 [email protected] so they can see what is the real issue.

    nop. Reckon support told me that my token is valid. But I still got invalid_client...and I don't know how to fix it from my side and what to do next. I used the postman as they said with exact the same input but still no good news. This process took me 2 weeks and no result. So we have to put a delay on the integration of Reckon...  If you have any solution, please let me know thx
