  title: PandaDoc REST API Logs Webhook Events API
  description: The PandaDoc REST API provides programmatic access to PandaDoc's document automation platform, enabling developers to create, send, track, and manage documents within their own applications. The API supports the full document lifecycle including generating documents from templates with dynamic data, collecting e-signatures, managing recipients, and tracking document status. Authentication is handled via API keys or OAuth 2.0, and a free sandbox environment is available for testing integrations before moving to production. An active Enterprise plan is required to access the production API.
