REST and (the newer) GraphQL APIs are the core technologies behind the vast most of today’s integrations. These APIs allow external developers to tap into the functionality of the major platforms and build in their custom functionality to suit their needs. The fundamental difference is that REST is an architectural design framework based on HTTP, while GraphQL is a query syntax that is not transport-dependent.

APIs are created so that users can use them as a bridge to connect to applications and services. There are thousands of APIs available for consumption, and each API is unique. But it’s really easy to consume APIs to extend the capabilities of your Linx apps, even complex ones that require OAuth 2.0 tokens. Let us show you how with a real-life example.
