Self-Documenting API Portal for n8n Webhooks with Bootstrap

This n8n workflow transforms your n8n instance into a self-documenting API platform by scanning all active workflows for designated webhook endpoints and dynamically generating a single, responsive HTML page. It uses a simple configuration: just add a 'Set' node named 'API_DOCS' with JSON metadata to any webhook workflow, and it instantly appears in the live docs with code examples, cURL commands, and response schemas.

Key benefits include automatic discovery without manual updates, zero external dependencies, and a dark-themed, Bootstrap-powered UI with accordions for clean navigation. Developers save hours on documentation maintenance, enabling faster testing and integration. The output is a callable URL serving professional docs out of the box.

Ideal use cases: Managing multiple webhook automations in production n8n setups, internal API portals for teams, or rapid prototyping where endpoints evolve frequently. Perfect for devops, SaaS products, or any n8n-heavy automation environment needing polished API exposure without tools like Swagger.
