API Development for Customer Data Management with Postman and Flask

Every modern business relies on APIs to store, retrieve, and update customer information securely. Understanding how to build and test these interfaces is a critical skill for developers and data professionals alike. This course guides you from the absolute basics of API concepts to building and testing your own customer data management system. You will gain the confidence to create backend routes, handle database interactions, and validate endpoints efficiently. What you'll learn: - Understand the core concepts of RESTful APIs, HTTP methods, and status codes. - Build a lightweight backend service using Flask to handle customer profiles and data. - Configure Postman collections and environments to automate API testing workflows. - Implement CRUD operations (Create, Read, Update, Delete) for customer data management. - Apply basic API security practices, including token-based authentication and request validation. - Analyze and debug API responses and error codes directly within Postman. The course begins with foundational definitions of API architecture before stepping through hands-on Flask development and comprehensive Postman testing scenarios. You will read structured explanations and analyze real-world code snippets to build your practical skills. Designed for beginners, this course requires no prior experience with Postman or Flask, though a basic understanding of Python is helpful.
