Hello,
I want to try to make a request from an API like with Postman with authentication (consumer secret, consumer secret, and token).
I tried with simple integration flow without authentication, and it works. I received the response in my payload. Like here Smoke Test Scenario with External Data Source | SAP Help Portal.
My integration flow:


But now I want to try with an another REST API that requires authentication. In postman it's easy to make requests.
Where should I put these fields (key and value) in my integration flow above ?

Thanks,
