Frequently asked questions
Dotloop scores F on the API Report Card. A public REST API is documented on GitHub Pages with OAuth 2.0, webhooks, and resources from Loops to Documents. Production access requires partner registration and a signed API License Agreement, with webhooks approved separately. There is no sandbox and no first-party SDK.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Dotloop API and MCP server so AI agents and internal tools can read and write Dotloop data. See the Dotloop integration docs at supergood.ai/docs/dotloop-api.
