Describe the problem/error/question

What is the error message (if any)?

Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Information on your n8n setup

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

So there are 2 seperate n8n instance right?

n8n A and n8n B.

Now you want to use n8n A to execute a workflow in n8n B ?

I think you can use a webhook trigger in n8n B

Then use n8n A Http Request node to send the request to the webhook url
