In HTTP Request use Body Data tab and of course fill-in Server Name, Port Number, Path and Update Method if needed:

And under HTTP Request add a Header Manager:

And add to it required headers:

Note Content-type might be different for you.

Answer 2

If your request works in Postman you can just record it in JMeter:

1. Configure JMeter for recording, the fastest way is using JMeter Templates feature

   • From JMeter's main menu choose File - Templates - Recording - Create
   • Expand Workbench - HTTP(S) Test Script Recorder and click "Start

2. Configure Postman for recording. You can "tell" Postman which proxy server to use (JMeter in your case) via --proxy-server command-line argument

    C:\\Users\\your_user_name\\AppData\\Local\\Postman\\app-xxx\\Postman.exe --proxy-server=localhost:8888

3. Execute your request in Postman
4. JMeter will capture the request and store it under Test Plan - Thread Group - Recording Controller
