Everything you can build on
Start with the data model, then the surfaces you build against it — query language, events, auth, agents, and extension points.
The data model
The seven core entities — contacts, companies, deals, actions, notes, calls, and meetings — and how they relate. The foundation every other surface is built on.
ExploreOQL
JSON query language over contacts, deals, actions, notes, calls, and meetings. Concepts, operators, functions, entities, recipes.
ExploreWebhooks
Real-time event delivery. Full reference: event matrix, payload encodings, delivery semantics, secret verification, config management.
ExploreExtension points
External ID, Quick-create URL, and Custom Button (beta) — small ways to connect without a full integration, and how partners combine them.
ExploreOAuth 2.1
Authorization-code flow for third-party apps acting on behalf of a OnePageCRM user. Scopes, refresh tokens, PKCE.
ExploreMCP
Model Context Protocol server. Surfaces describe, context, query, create, and update tools to AI agents.
