# V3 (Alpha) API Reference

> Overview of the DualEntry Public API V3 alpha endpoints. V3 is an unstable preview channel, not yet available for production integrations.

You're browsing **V3-alpha** (`/public/v3-alpha/`). This is a **preview channel** of the DualEntry Public API.

<Warning>
  **Do not build production integrations against V3 yet.** While in alpha, endpoints, request/response shapes, and behavior can change without notice, and V3 is not covered by the [Versioning](../../guides/versioning-policy) guarantees. Use [V2](../resources-v2) for new integrations.
</Warning>

Browse the endpoints in the sidebar, or download the [OpenAPI 3.1 spec](/developers/openapi/resources-v3-alpha.json).
