This API is under development. Its contract may change before release. These endpoints are separate from the current API at api.watchdog.no; continue using the current API reference for existing integrations.
The new API separates business documents from the work that produces them: Create an invoice directly from structured JSON, or upload a file and submit it for import. A single import creates one workflow run with one item. Read the item to find its resulting invoice. Processing failures and non-invoice files remain import outcomes; they do not create pending invoices.

Try the development API

Use the API base URL provided for your development environment. For a local checkout, follow apps/api-worker/README.md in the repository and start the Worker with:
The examples and generated endpoint pages use http://localhost:3500. Replace that base URL with your development deployment’s URL when applicable. A documentation preview does not deploy the API or start import processing; file imports also require the workflow service described in the setup. Start with the quickstart for copyable requests, then use API conventions, invoice semantics, and workflow runs to interpret the responses.

Reference and release status

Every endpoint page is generated from the same OpenAPI contract as the API client. Download the preview specification for your own tooling. The endpoint schemas define the exact inputs, outputs, permissions, and errors; the guides explain how to use them together. The initial modules are invoices, Documents, imports, workflow runs, suppliers and recipients, and organization teams. Existing accounting integrations and frontend workflows retain their current backend paths until their separate migration. The current API reference remains available throughout that transition.
