Flask is one of the most lightweight and flexible Python frameworks — perfect for creating REST APIs quickly. In this post, we’ll go step-by-step through building a simple REST API using Flask.

You’ll learn how to set up Flask, define API routes, handle JSON data, and test endpoints with Postman. By the end, you’ll have a working API that can be used for web apps, mobile apps, or automation scripts.

Key takeaways:

• Setting up a Flask environment
• Creating GET and POST routes
• Returning JSON responses
• Testing endpoints with Postman

This is a great starting point if you’re planning to integrate Python with your front-end or mobile applications.
