Never heard of REST API? - API is an Application Programming Interface made up of a set of rules and mechanisms which allow applications to interact with one another. If you require specific data for your own app, you can send a request to an API, and it can return the data you need.

When you receive a response from an API, the way the data is presented is based on Representational State Transfer (REST). REST is an architectural style for writing API.

A RESTful web service or system presents data in a suitable format that is convenient for the client. Data can be presented in a variety of formats, such as JSON, HTML or XML. For example, all iLovePDF's API responses are returned in JSON format.

There are loads of public REST APIs online that you can use to retrieve useful data for your own apps and services. Check out Web Concept's video for some great examples. With iLovePDF's REST API, you have all the information you need to develop your own PDF tools for your app.
