This post is a member of the following glossary:

• [Contentstack] [SaaS] [Headless] CMS Glossary Index – Deliverystack.net

An SDK is a technology-specific programming library that allows developers to integrate with and customize existing software components.

As opposed to developing custom software that builds on and runs within the CMS itself, SDKs provide customer systems with access to existing CMS instances, repositories, and features. With decoupled and headless CMS, SDKs abstract the HTTPS APIs provided by the CMS for specific technologies such as JavaScript and .NET.

While any client technologies could invoke their services, decoupling allow SDKs for any number of technologies. Headless CMS vendors typically provide SDKs to wrap their HTTPS APIs for a wide variety of technologies.
