WebhookDocs: generate swagger preview of your active workflows

Description

How it Works

This meta-workflow is designed to intelligently scan all your active workflows in n8n, identify those that contain Webhook nodes, and automatically generate a Swagger (OpenAPI) specification based on them.

The output Swagger document reflects all accessible endpoints from your Webhook nodes, making it easier to:

Visualize your API structure
Share your endpoints
Integrate with tools like Postman or Swagger UI

Enhanced Parameter Support

If you want the Swagger to reflect request parameters (e.g., query or body fields), you can annotate your Webhook nodes using the Note section. When configured properly, these annotations enrich your Swagger documentation with parameter names, types, and descriptions.

Setup Steps

Add the WebhookDocs to n8n
Import the WebhookDocs JSON file into your n8n instance.
Activate the WebhookDocs (you can also use the test-endpoint)
Annotate Webhook Nodes (Optional but Recommended)
To enable parameter documentation, open the Note section of each Webhook node and add annotations in the following format:

//@body field_name string description
//@query field_name string description
