Paragon Workflows API

  title: Paragon ActionKit Workflows API
  description: 'Unofficial, community-authored OpenAPI description of Paragon''s embedded integration platform APIs, compiled by API Evangelist from Paragon''s public documentation. Paragon exposes several distinct API surfaces across different hosts: the Connect API (zeus.useparagon.com) for managing authenticated users, connected credentials, integrations, workflow triggers, and proxied third-party requests; ActionKit (actionkit.useparagon.com) for listing and running prebuilt LLM-ready actions; and Managed Sync (sync.useparagon.com / managed-sync.useparagon.com) for normalized third-party data ingestion and permission checks.

    Nearly all requests are authenticated with a Paragon User Token, an RS256-signed JWT that your application signs with the private signing key from the Paragon dashboard (Settings > SDK Setup) and that Paragon verifies with the matching public key. In production most developers use Paragon''s Connect SDK and Connect Portal, which sit in front of this API; the raw HTTP surface documented here is used for server-side and headless integrations.

    Endpoint paths and payloads are approximate representations of Paragon''s documented behavior and should be verified against the official docs.'
