New: the Invoice API

You can now create invoices in kreativ.mind from an external system: one POST request and the invoice is issued — with a gapless number, a finished PDF and a public link.

What the API does#

• Issues immediately: every request creates a real, numbered invoice including the PDF.
• Creates clients automatically: without a client id, a name is enough — the new id comes back in the response for reuse.
• Secure by design: rotatable tokens, bound to one sender, stored server-side only as a hash.
• Idempotent: an Idempotency-Key prevents duplicate invoices on network retries.

How to get started#

Create tokens under Settings → Billing. All details, field references and examples live in the documentation.

The invoice API is plan-dependent — it must be enabled in your package.
