How can I integrate Ultipa Graph DB in an n8n workflow to build a Knowledge Graph?

I want to use n8n to build and query a Knowledge Graph on Ultipa Graph DB. The flow should:

  1. authenticate to Ultipa’s RESTful API proxy,

  2. run UQL queries (reads + writes), and

  3. bulk-insert nodes/edges from JSON events (or CSV) coming from other n8n nodes.

Thanks Rinaldo
