APIs

Web applications don't live in isolation. They often work together with other applications.

For instance, if you have an online store, it might use Google or Facebook to let users log in, then use Flutterwave or Paystack for checkout.

To connect your application to those applications, you make use of an interface. An Application Programming Interface, or API, is how an application communicates with other programs.

Every API is different, but there are skills you can learn that make it easier each time you have to deal with a new API. Practicing with different APIs and designing your own API will help you get a handle on how to connect your application to other services.

You'll practice reading and writing documentation, navigating API authentication, and patterns like webhooks and rate limiting.
