APIs & Integrations

APIs & Integrations is a practical corner for anyone building, testing, documenting, or learning how software talks to other software. The listings here cover the full API lifecycle: Swagger helps teams work from OpenAPI, AsyncAPI, and JSON Schema specs through code generation, documentation, testing, governance, and standardization; Postman brings together API design, testing, mock servers, documentation, monitoring, sharing, and collaborative workspaces; and RapidAPI API Hub gives developers a place to search for third-party APIs, inspect docs, test endpoints, and compare usage plans before committing to an integration.

There’s also a strong learning and reference layer here. MDN Web Docs is the dependable stop for web platform fundamentals and browser APIs, while Android Developers offers Google’s official guides, API references, Android Studio downloads, UI guidance, and publishing resources for Android apps. Codecademy adds guided technical learning with browser-based practice, projects, workshops, and career or skill paths. And when you just need something simple to build against, JSONPlaceholder provides a public REST API with sample JSON data for prototyping, tutorials, and frontend testing. Together, these resources make the subcategory useful whether you’re exploring an unfamiliar API, teaching yourself the basics, or setting up a more structured workflow for a team.
