Composition API

Compose a Publication

Required scope: public-api:read

Description

The Composition API loads a Publication with all required information to render a whole document/page with one request.

Advantages
  • Make only one request to get all the required information to render a publication
  • High-performing and efficient preloading of references (e.g. lists, includes, other references)
  • Useful for a pull architecture
  • Deduplication of document teasers
  • The only endpoint which is able to resolve includes
Use Cases
  • Load a Publication with all required information to render a whole document/page within one request.
