# Changelog

> Changes to the Watchdog API, including deprecations.

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="September 2026" description="The new Watchdog API">
  The new API is available at `https://api-canary.watchdog.no` and replaces the [legacy
  API](/api-reference/introduction). `api.watchdog.no` moves over to it later; after that, you only
  need to change the address.

  * [Upload invoices](/api-preview/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.
