Functions

Overview

Functions are backend serverless workloads that run on Contentful’s infrastructure and are enabled through the App Framework.

Functions allow you to run custom code on the Contentful platform, augmenting parts of the GraphQL and Content Management API. This unlocks limitless possibilities to adapt Contentful to your business needs.

NOTE: Functions are only available for Premium plans and Partners.

Types of Functions to extend Contentful:

• App Event functions

These functions allow custom backend logic to be executed within the App Framework, ideal for various integrations and custom workflows.

NOTE: App Event functions are in beta. Sign up for early access here.

• App Action functions

These functions provide apps an easy way to expose generic capabilities to their own frontends as well as to other apps.
