We publish a dated minor release roughly once a month. Pin your integration by setting Geldstuck-Version: YYYY-MM-DD - see versioning.

​
2026-04-01 - Document review & multi-endpoint secrets

​
2026-04-01
Current release
New
  • Document review API (/v1/document-review) - multi-round review workflow with signed decisions.
  • Per-endpoint webhook secrets. Register an endpoint with its own whsec_ so rotations are isolated.
  • webhook.delivery.failed meta-event.
Changed
  • transaction.status.changes renamed to transaction.status.changed. The old name still fires for 6 months.
  • Pagination now uses cursor-based (starting_after, ending_before) instead of offset. Offset parameters still work but are deprecated.
Deprecated
  • GET /transactions/gettoken - use GET /transactions/:id and read token from the response.

​

​
2026-01-15
New
  • POST /v1/tenants/bulk for white-label partners.

Changed
