Roadmap
What's actually built today versus what this site documents as the target design.
This site documents the target design for the SUMU Peppol API — the specification the integration will be built against. It is not live yet, and no endpoint described here can be called today.
What's available today instead: logging into the SUMU dashboard and using the built-in e-invoicing flow to generate, preview, and download e-invoices directly. That flow has no API and no external integration surface — it's for use inside the dashboard only.
Open before this ships: an access-control model for organisations that want to issue scoped, restricted credentials rather than one all-access key per organisation — see the callout on Authentication. Everything else in this reference — every endpoint, field, and status value — reflects the confirmed specification.
