Make OAuth2 calls from ABAP to Autodesk Forge

[yasser_aoujil]

Hi experts,

I am new to the OAuth2 and Autodesk Forge API.

I am starting to learn about how to integrate both, for now I am stuck on how to make an http post from ABAP code to the authentication endpoint of the Forge API to get the access token. I started looking at this link https://wiki.scn.sap.com/wiki/display/Security/OAuth+2.0+-+Integrating+access+protected+web+services... but I can't get the whole picture if that's what I really need.

Specifically I need help on how can I do the equivalent of the following call using curl (as it come in this link https://developer.autodesk.com/en/docs/oauth/v2/tutorials/get-2-legged-token/):

curl -v 'https://developer.api.autodesk.com/authentication/v1/authenticate'
  -X 'POST'
  -H 'Content-Type: application/x-www-form-urlencoded'
  -d '
    client_id=obQDn8P0GanGFQha4ngKKVWcxwyvFAGE&
    client_secret=eUruM8HRyc7BAQ1e&
    grant_type=client_credentials&
    scope=data:read

Spaces in the call are put for readability purpose.

Any help or insights are appreciated.

First you need to retrieve a IF_HTTP_CLIENT-Instance with the factory-methods in the class CL_HTTP_CLIENT.

With this instance you create an instance of class CL_REST_HTTP_CLIENT and set the request-body in method IF_REST_RESOURCE~POST
