Create a node from a OpenAPI json file

[RedPacketSec]

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.

I think this is an duplicate to:

Swagger/postman codegen

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)

Building a custom node using an Open API spec

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 - 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!

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