  description: >-
    The Prolific API is a versioned REST interface for the Prolific online research
    participant recruitment platform. Researchers use it to programmatically create
    and publish studies, review and approve submissions, manage participant groups,
    projects and workspaces, apply demographic filters and requirements, pay bonuses,
    message participants, and subscribe to event webhooks (hooks). The API is served
    from https://api.prolific.com/api/v1 and follows a standard REST pattern: a
    collection endpoint (.../resource/) for GET (list) and POST (create), and an
    element endpoint (.../resource/{id}/) for GET, PATCH/PUT, and DELETE. All
    requests are authenticated with an API token supplied in the Authorization
    header as "Token <your token>".
