External API

External APIs enable your app to connect with services outside your own system, such as Stripe for payments, Google Maps for location data, or Facebook for social login. They provide access to features and data maintained by other providers without requiring you to build them from scratch.

External APIs are different from internal APIs, which operate only within a single organization or product ecosystem. By integrating with external APIs, developers can reduce development time, expand functionality, and create more seamless user experiences. Examples include pulling weather data, processing credit card payments, or syncing calendars.

These APIs often require authentication keys, provide documentation for developers, and may include rate limits to manage usage. They are essential in modern app development, enabling flexible and scalable integrations. While powerful, using them also means relying on external services to stay online and secure. Choosing well-documented, trusted APIs helps ensure reliable connections.
