Public API v1

  • Public API v1. Bearer API keys (fsk_ prefix) created from Settings > API keys. Endpoints for workspaces, packages (list, create, get, act on, delete) and templates (list, create, get, update, delete, instantiate). Requests act in one workspace per call via the X-Workspace-Id header. See the developer quickstart.
  • Webhooks. Register HTTPS endpoints from Settings > Webhooks or POST /api/v1/webhooks. Nine package and session events, HMAC-SHA256 signatures, automatic retries with exponential backoff, and a per-endpoint delivery log. See Webhooks.
