Collections

LAST EDIT Mar 18 2024

Collections enable you to store information to Stream. This allows you to use it inside your feeds, and to provide additional data for the personalized endpoints. Examples include products and articles, but any unstructured object (e.g. JSON) is a good match for collections.

Collection entries can be embedded inside activities and used to store nested data inside activities. When doing so, Stream will automatically enrich your activities with the current version of the data (see later section). Collection endpoints can be used both client-side and server-side except the batch methods that are only available server-side.
