Create node

Is it possible to create automatically create a set node with predefined parameters?

I have this data json structure extracted, I need to insert my info in the “string” fields in order to be able to create the HTTP resquest I want.

Is there a way to quickly import the parameters and be able to change just the “string” fields?
Or do I need to manually insert the parameters in a set node?

Hi @suardim, you can programmatically create workflows including nodes, though I am not 100% sure where your snippet comes into play.

Workflows can be created (and updated) through the REST API for example: API reference - n8n Documentation

As for the exact payload to use, I reckon your best bet would be to build the workflow including your Set node once manually. Then take a look at the resulting workflow JSON data and use this as the basis for any new workflows including such a node.
