Code-based API automation

Postman scales to a point; code scales further. Automate with Python requests, JavaScript fetch/axios, or Playwright APIRequestContext — pick one stack.

Step 1 of 4

Pick your stack

Python: requests + pytest. JS: fetch + Jest/Vitest. Playwright: request fixture for hybrid UI+API teams.

Example

# Python + pytest + requests
import requests

def test_get_user():
    r = requests.get("https://jsonplaceholder.typicode.com/users/1")
    assert r.status_code == 200
    assert "@" in r.json()["email"]

Do this now

Install stack. One test: GET users/1, assert status 200 and email contains @.
