  title: Paubox Forms Submissions API
  description: 'The Paubox Forms API has two kinds of endpoints. Public, respondent-facing endpoints (retrieving a form definition for rendering and submitting a form response) require no authentication. Authenticated management endpoints (creating, listing, updating, copying, archiving forms, and reading or exporting submissions) require a Paubox API key with the "forms" scope, sent as `Authorization: Bearer YOUR_API_KEY`. API keys are generated in the Paubox dashboard.
