  description: 'The SignSealShip partner API: create sign / notarize / ship orders, create Verified Closing Rooms, seal Closing Passports and Proof Passports, and manage webhooks. Partner endpoints authenticate with a bearer key (`Authorization: Bearer sss_pk_...`); public verification endpoints need no key — possession of the verify, room, or order code is the authorization. See the Guides for full prose, rate limits, and signature verification.'

      summary: Create an order
      description: Create a sign / notarize / ship order for a client's own completed document. Send the PDF as the multipart part `document`, or reference a fill-online result with `fill_token` — exactly one of the two, never both. Pricing is computed entirely server-side from the B2B price book with your subscription tier's discount applied automatically; there is no client-sent amount anywhere in the API. Order state advances only via the verified Stripe webhook — minting a checkout session (or a payer landing on the success page) never changes state. Rate limited with `partner-write` (60/min per key).
