How can I programmatically generate nodes in a flow?

General

  1. export a simple flow - a selection of nodes (i used an Inject and a Debug node)
  2. copy its json - because obviously i wasnt gonna sit and type all that in :wink:
  3. based on the docs constracted the body of the request and pasted in nodes property the json from step 2
  4. deleted my test flow with the Editor so there wont be a clash of ids / names etc
  5. tested the POST with POSTMAN software
  6. translated the request with it to Curl, for you to have fun
curl --location --request POST 'http://192.168.0.7:1880/flow/' \
--header 'Content-Type: application/json' \
--data-raw '{
