REST APIs, JSON, and HTTP in plain English

Before you write a single API call you need to understand the plumbing:

• What a REST API actually is and how HTTP requests work
• JSON structure: objects, arrays, strings, numbers
• GET vs POST — when and why
• Reading API documentation: endpoints, parameters, response shapes
• Using curl and Postman/Hoppscotch to test any API manually

By the end you can look at any API reference and understand what it expects.
