Playwright with Python #29 - POST API Requests | Create Users & Validate Responses

Building on our previous lesson about GET requests, this video tutorial guides you through creating users using Playwright with Python. You'll learn to send JSON payloads and handle responses effectively, essential skills for any QA engineer. This demonstration focuses on POST requests for data creation, a key aspect of automation testing and robust software testing practices. Whether you're a beginner or leveling up your automation testing career, this step-by-step walkthrough shows you how to automate real-world user creation APIs and verify your data end-to-end using Playwright with Python. 📌 KEY TOPICS COVERED: How POST requests differ from GET requests in API automation Setting up authentication tokens and headers in Playwright Python Structuring JSON payloads for user creation APIs Sending POST requests with URL, payload, and headers Understanding HTTP status code 201 (Created) vs 200 (OK) Asserting response status codes and validating they fail correctly Extracting and parsing JSON responses Verifying response data matches the payload you sent (name, email, ID) Debugging failed assertions live What's coming next: dynamic test data and data-driven testing ⏱️ TIMESTAMPS: 00:00 Introduction & what you'll learn 00:47 Signing up & getting your authentication token 01:04 Exploring the Create User POST API endpoint 01:30 Understanding the request body (name, email, gender, status) 01:49 HTTP 201 response — what "Created" means 02:17 Setting up the test file in PyCharm 02:50 Copying and adapting GET request code for POST 03:42 Building the JSON payload in Python 05:03 Defining headers with authorization token 06:09 Sending the POST request with URL, data, and headers 07:23 Adding status code assertions (201 vs 200) 08:42 Running the test — watching assertions fail and pass 10:20 Extracting and printing the JSON response 11:14 Asserting name, email match the payload 12:35 Asserting the response contains an ID field 13:26 Debugging a failing assertion live 14:11 Summary & what's coming in the next tutorials 📢 Ready to level up your QA career? 👉 Subscribe for weekly Playwright Python tutorials 👍 Like this video if it helped you 💬 Comment below: What API topic do you want next?
