  title: SignSealShip Partner Closing Passports API
  version: 1.0.0
  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.'
