An API is a way for a program to interact with another program. By using third–party APIs from your code, you can utilise functionality developed elsewhere. By creating an API to access your own data, other programs can take advantage of your services in a secure and easy fashion.

The essential skills required to use and develop APIs with PHP.
Unless you create every component of your application from scratch, your code will need to interact with external services – for example a payment gateway, or currency data. To use such services, you need to consume their APIs. On this course you’ll learn how to do this from PHP, and also how to create an API so that external programs can interact with your application.
