Create mapping template node

Developing Nodes
1

Hi experts,

I'm quite new to NodeRed development. I try to implement an integration for a Rest API that requires a specific json payload. I would like to create my own node that allows to map certain fields in that json structure. Right now I place a function node in front of the POST request where I map the fields and create the json. This works fine and is very flexible. But I would like to give the user more convenient functions (users dont know the json structure).

It would be great if I could create a node that has already the json fragment as a template and allows the user to map field from msg. of even better from jsonata espression

Any suggestion would be greatly applreciated.

Thanks in advance,

Marco

I have something similar here - not sure if it's close enough - node-red-contrib-remap (node) - Node-RED

Maybe a subflow is the sweet-spot between a function node and dedicated node?

https://nodered.org/docs/user-guide/editor/workspace/subflows

You can control the basic input values. In the Subflow, you can request the api and prepare the respond for the users.
