Many services offer OpenAPI v3 or Postman Collection export of the API capabilities.

Would be nice if we can just import an OpenAPI v3 JSON file and have that as a working custom node.

> OK, it might be an urge work, but it would be really great to have a code generator to create custom nodes from a swagger file or a postman collection (like in Microsoft flow)

> Hello Everyone, This is my first attempt to play around with the n8n, explicitly referring to creating a custom node. Is it possible to use an open API specification ( formerly swagger ) to implement the resource and operation parameters for the NodeType interface? Thank you!

Hi!  
Having built-in mechanisms for parsing and creating nodes from OpenAPI would be awesome improvements for n8n, agree 👍

While we’re waiting we created [n8n-openapi-node](https://github.com/devlikeapro/n8n-openapi-node) - the lib allows you to turn OpenAPI to n8n node pretty quickly.

We also have few real-world examples where we used the lib to generate n8n community node from OpenAPI: [GitHub - devlikeapro/n8n-openapi-node: Turn Your OpenAPI (Swagger) spec into a n8n node! · GitHub](https://github.com/devlikeapro/n8n-openapi-node?tab=readme-ov-file#use-cases)

Here’s **ChatWoot** node we got from their official OpenAPI spec:
