API changelog

Changes that affect integrations with the Tario API, breaking changes first.

Breaking changes are announced here before they ship. Routes with eTax names are kept for compatibility. Adding endpoints or fields is not considered breaking.

2026-09-27

  • Public reference at tario.io/docs/api, generated from the OpenAPI specification.
  • MCP tools search_help and get_help_topic to query the user guide.

2026-09-22

  • Breaking: POST /api/hacienda-inbox (unauthenticated relay) was removed. XML reception uses POST /api/hacienda-inbox/xml with a company token.
  • New queue GET /api/v1/facturas-compra/lista-no-aceptadas: purchases without a receiver message.

Attachments

  • New generic attachments/{type}/{id} endpoints to list, upload, download, and detach attachments on any record.
  • invoices/{id}/attachments keeps working; its sort_order starts at 0 and DELETE records who detached the file (soft delete).
