OAuth problem : Unable to authorize access because the client configuration is invalid: invalid_request
For testing purposes to decide whether to go with this I am at this moment using the free-trial period.
I am trying to get the OAuth token on :
I tried also other scopes, like user_login:self+agreement_send
Application ID: CBJCHBCAABAAuNaCVzG8tTMkcpuvNo9_aLgrzN4IXJZh
Client secret: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxE_dv
Redirect uri is set the same as it is set in the API application settings. I tried in the browser in Postman and in ARC and get the same result: 'Unable to authorize access because the client configuration is invalid: invalid_request'
Scope settings:

best regards
