  title: dotloop Public API v2 Account Participants API
  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/.
