Authentication
Send an API key as a bearer token. The key must carry the billing.view permission; a key without it is refused with 403, not 404.
Where your organisation id goes
This endpoint takes org_id as a query parameter. Leave it out and the call covers your whole tenancy subtree; send it to narrow the call to one organisation.
Your organisation id is on the API keys screen in your dashboard, beside the key itself. It is the same id in every call you make.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X GET https://api.zinndigital.com/v1/invoices \
-H "Authorization: Bearer zdk_live_…"Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
The organization's billing history — every **invoice and credit note** issued to it, newest first, with its lines, its payment summaries and the captured amounts. Cursor-paginated, filterable by `status`; RLS-scoped; requires `billing.view`. **These are the real legal documents (docs/34 §1).** Each is an immutable snapshot with a gapless, per-entity `ZD-INV-YYYY-NNNNNN` number, a captured tax treatment and its own frozen FX rates. `document_type` separates an invoice from a credit note; `credits_invoice_id` says which invoice a credit note un-bills. ⚠️ **The document is issued by a sweep, a couple of minutes after payment, not synchronously at checkout** (docs/34 §4.1). Render a pending state for a just-placed order rather than assuming the document is there the moment checkout returns. `pdf_url` stays `null` until PDF rendering lands (#708).
