connect to the api's of external application from workflow
I am trying to create a callout task to get data from the api's of an external application, into Zuora, but I am getting the attached error. I am using the oauth_2 authentication type, with client_id and client_secret, using username and password. The same credentials work via postman, when a bearer is generated automatically. What could be wrong?
What should I use in the Site field?
I am attaching also the header I am using
