What the API covers

Every domain operation - forms, submissions, users, and events - is a first-class REST endpoint.

Form CRUD & Lifecycle

Create, read, update, and delete forms with full version tracking. Publish and archive states let you evolve forms without breaking historical data.

Submissions & Partial Saves

Respondents save progress mid-form and resume from any device. Completion flags and submission tokens handle the session lifecycle.

User Management

Create and manage users via the API. Role-based access control determines who can manage forms, read submissions, or only submit.

Swagger / OpenAPI

Full OpenAPI spec generated at runtime. Explore and call every endpoint directly from the Swagger UI in the browser - no client code needed to get started.

Webhooks

Push notifications to any HTTP endpoint on SubmissionCompleted, FormCreated, FormUpdated, and FormDeleted events. Configure per-form or globally.

Pre-filled Forms

Seed form fields from your own data source so returning users never re-enter information. Useful for CRM-driven intake flows.

Open Source

The API is open source and ready to run.
