# Generate Swagger docs for n8n webhooks with interactive UI
This automation automatically generates up-to-date Swagger (OpenAPI) documentation based on all active webhooks in your n8n instance. The spec is served through an interactive Swagger UI page, making it easy for external systems to integrate and developers to maintain consistent API references. Ideal for teams that value self-service API documentation and real-time accuracy.
## Who it´s for
- Developers using n8n to build APIs
- Integration engineers needing clear webhook documentation
- n8n administrators automating workflow documentation
- Teams deploying internal APIs with auto-generated specs
## What the automation does
- Triggered via HTTP webhook
- Fetches all active workflows from the n8n instance using its API
- Analyzes nodes containing webhooks, extracting paths, HTTP methods, and parameters
- Builds a valid OpenAPI YAML specification
- Serves the result via Swagger UI for browser-based viewing
- Ensures documentation reflects current state on every request
## What´s included
- Ready-to-use workflow for n8n + Webhook API generator
- Trigger and handler logic powered by JavaScript
- Integrations with n8n API, Swagger UI, and js-yaml
- Basic text instructions for setup and adaptation
## Requirements for setup
- Access to an n8n instance with read permissions for workflows
- Ability to host or expose a static endpoint for Swagger UI rendering
- Installed js-yaml module if processing outside n8n
## Benefits and outcomes
- Automatic doc updates without manual edits
- Faster third-party system integrations
- Reduced integration errors due to accurate specs
- Centralized API documentation within n8n ecosystem
- OpenAPI standard compliance for tooling compatibility
