How to get token using destination in CAPM based service?

[karanbahl]

Hi All,

I want to instantiate a workflow instance from my CAPM based service for which I need to pass the authorization header token. I am able to pass it by passing the headers as below; however I want to replace this method by a dynamic one; for example a destination so that I do not to pass the authorization as below. Any suggestions; how can we do it?

jhodel18 - any suggestions?

Regards,

Karan

  var options = {
  'method': 'GET',
  'url': 'https://scp/oauth/token?grant_type=client_credentials',
 'headers': {
               'Accept': 'application/json',
               'Content-Type': 'application/json',
               'Authorization': 'Basic ************************'
                        }
              };

Hi Karan,

I haven't really tried SCP Workflow yet, but based on what you are doing -- you are manually getting the JWT token. If your CAP-based service is authenticated by the same UAA service then that means you already have the token within the CAP framework.

I have written a blog post about how the User Authentication works in CAP -- https://blogs.sap.com/2020/07/20/cap-demystify-user-authentication/

The security context is the decoded JWT Token. If you can get that from within CAP then it should be the answer to the dynamic way you are looking for.

I hope it helps!
