# Legacy API v1 snapshot

> Frozen Case Management API v1 and Partner API v1 documentation

<Warning>
  This page documents a frozen v1 API. It receives only critical correctness or
  security corrections. For new integrations, use the [current API](/api-docs/overview)
  and follow the linked [migration guide](/api-docs/legacy/overview#migration-guides).
</Warning>

This documentation snapshot was restored from docs commit `4c7d591`
on 2026-09-25, the last v1 documentation published before the current APIs.
It preserves the historical contracts and guidance for existing v1
integrations. Corrections made after the snapshot are listed in the Case
Management and Partner release notes.
