Collections API

A collection belongs to a user and contains artworks. A collection may be public or private: public collections are available for everyone to see and private collections are not. Every user has a default collection, often referred to as "Favorites" and called "Saved Artwork" by default.

Retrieving Collections

You can retrieve a user's public collections by following the "public_collections" link from a user. Users can retrieve their own public and private collections by following the collections link from user details.

curl -v "" -H "X-Access-Token: ACCESS_TOKEN"

This endpoint accepts the following parameters.

Name Value
user_id Collection owner (user) ID, required.
private Also retrieve private collections.

The response is a paginated result with embedded collections.

Retrieving a Collection

Users can retrieve a specific collection by ID by rendering the "collection" link template from root.

curl -v "{id}?user_id=USER_ID" -H "X-Access-Token: ACCESS_TOKEN"

Users are only authorized to retrieve their own private collections.

Creating and Updating Collections

You can create a collection with POST to "collections" and update a collection with PUT on "collection". All fields from the collection JSON format below are supported, except "id". A "user_id" is required.

See this topic for documentation on how to add artworks to a collection.
