List filter choices
Browse visible, valid choices in catalogue order, including selectable parents. Returns a flat, always-paginated collection without match metadata or nested children. Instructional participant-ID placeholders are not selectable choices. Empty enumerable filters return an empty collection. Permissions and catalogue restrictions apply before searching or counting. Self, next and previous links preserve applicable query and catalogue context, including workspace_id. Pagination links follow shared API conventions. Empty results retain the same envelope.
Authentication
The Prolific API uses API token to authenticate requests. You can create an API token directly from your settings.
Your API token does not have an expiry date and carries full permission, so be sure to keep them secure.
If your token is leaked, delete it and create a new one directly in the app.
In your requests add Authorization header with the value Token <your token>.
Path parameters
Query parameters
Zero-based result offset. An offset beyond the collection returns an empty page.
Restrict the catalogue by tag, for example custom-group.
