Problem Acessing Orchestrator API from External Application

I am trying to use API from external application to acess Cloud Orchestator and followed all instructions we have in the following links:

However, even providing client secret and id and other parameters mentioned bellow, all I keep receving is Invalid Request as result:


"error": "invalid_request"


The instruction used are presented bellow. Anyone has already managed to solve that ?

Client Credentials
For confidential applications to access application scope, the external application requests an access token by sending a POST request that includes the client_id and client_secret to the Identity Server token endpoint: .
If you are using Postman or a similar tool, use the content type application/x-www-form-urlencoded .

Sample request body for a token request

    "grant_type": "client_credentials",
    "client_id": "{app_id}",
    "client_secret": "{app_secret}",
    "scope": "{scopes}"

I managed to make it work.
It worked using postman with this configuration of header parameters:

Yep that is right @carlossergio1 you can also configure Postman Collection Authorization configuration like this:

Then for every folder or request within the collection make sure you inherit the authorization configurations from the parent.

Thank you for your support.
