  title: dotloop Public API v2
  description: >-
    The dotloop Public API v2 is a documented, OAuth2-secured JSON REST API for
    the dotloop real estate transaction management platform (a Zillow Group
    company). It exposes the authenticated account, profiles, loops
    (transactions) and their structured details, folders, documents,
    participants, tasks, activities, contacts, loop templates, and webhook
    subscriptions, plus a Loop-It facade that creates and populates a loop in a
    single call. All requests and responses are `application/json` (document
    upload uses multipart form-data). Access is currently restricted to
    INDIVIDUAL profiles. Endpoints and paths in this document are grounded in
    the published developer guide at https://dotloop.github.io/public-api/.
