OAuth2 : is it possible to work on client_credentials without basic auth header

Is it possible to work on ‘client_credentials’ grant type to grant tokens just provision client_id and client_secret in post request content-body without the Authorization header (from Implied Basic Auth) ?

I think it is somewhat redundant for me :tired_face:

Sorry for my poor english…

I issued a request like this one :

POST /oauth2/token HTTP/1.1
Content-Length: 135
Accept: /
Cache-Control: no-cache
Connection: keep-alive
Content-Type: application/x-www-form-urlencoded


and i got an error :

{“error”:“invalid_request”,“error_description”:“The request is missing a required parameter, includes an invalid parameter value, includes a parameter more than once, or is otherwise malformed.”}

Is there any way to get it working properly?

I believe you will always need that header
