# Changelog

> Changes to the Watchdog API, including deprecations.

The API is in beta, and may change without notice until we release a stable version. That release
is announced here.

Once the API is stable, new endpoints and fields are listed here as they arrive. Anything deprecated
is marked in the endpoint reference, listed here with the date it stops working, and emailed to the
customers who use it at least 3 months before.

<Update label="October 2026" description="The new Watchdog API">
  The new API is available at `https://api.watchdog.no` and replaces the legacy API.

  * [Upload invoices](/api-reference/upload-invoices) in two steps, then optionally follow the import and
    the check.
  * Starting an import returns the import itself. A file Watchdog already has comes back straight away
    as a `duplicate` pointing to the existing invoice.
  * An import takes up to 50 attachments, of any file type.
  * `403 invoice_processing_capacity_exhausted` means your organization has no invoice processing
    capacity left.
