Cookies in API tests: a round trip

Automation taskMediumJava only

"How do you test an API that uses session cookies?" In this lesson you take a cookie from one response and send it back with the next request, the way a browser does.

Cookie Round-Trip

Cookie Round-Trip

A real-world pattern: receive cookies from one endpoint, then send them to another.

  1. GET /cookies/set → extract cookies from the response
  2. GET /cookies/read → send the extracted cookies and verify they arrive

Expected output:

Round-trip session_id: abc123
Round-trip theme: dark
