About CMS APIs

Manage website content across all devices with CMS APIs.

What is a CMS API?

A content management system (CMS) application programming interface (API) is a RESTful web service. The third-party service allows developers to add content management system functionality to their websites.

An API for CMS may also be considered to be a headless CMS. A headless CMS separates the backend storage depository from the frontend display. An API for CMS is the middle component that bridges both backend and frontend together. This allows for fast retrieval of content to display on any device.

How does a CMS API work?

CMS APIs utilize the HTTP GET and POST request methods. The type of request method used depends on how an API’s endpoint is intended to function. Developers embed endpoints into their projects to connect to the data sources of the API provider. Results are sent back in JSON or XML format.

Who is a CMS API for?

An API for CMS is for novice and expert developers that want to save time coding the CMS functionality into a website they create for a client.

Businesses that want to create and manage content across all of their devices or applications will also find APIs for CMS useful.

Why is an API for CMS important?

APIs for CMS are essential tools for developers because they help them build large-scale websites with ease that match or exceed the competition. Developers can focus on other aspects of the project and let APIs handle many of the CMS duties.
