WebhookDocs: Auto-Generate Swagger for n8n Webhooks

This meta-workflow intelligently scans all your active n8n workflows, identifies those containing Webhook nodes, and automatically generates a comprehensive Swagger (OpenAPI) specification. The resulting document details all accessible endpoints, methods, and paths from your Webhooks, providing a visual API structure that's easy to share or integrate with tools like Postman or Swagger UI.

Enhanced support for request parameters comes via simple annotations in the Note section of Webhook nodes (e.g., //@body field_name string description). This enriches the Swagger output with query params, body fields, types, and descriptions, making your API docs production-ready without manual effort.

Ideal for developers managing multiple n8n workflows with webhooks—save hours on documentation, improve team collaboration, and streamline integrations. Setup is quick: import, activate, annotate optionally, and access via /webhook/swagger on your n8n instance. Perfect for API-heavy projects in devops, SaaS, or automation pipelines.
