How I can work with wait node on webhook url call?

Describe the problem/error/question

I have a simple workflow with wait node and I want to resume the flow on a webhook call. And I have decided to use a third party webhook caller for the flow to be resumed.
But, as the webhook is dynamically generated so I don’t know what url I must use in the third party service. because the executions number is being changed on every run.

And what do you suggest I should use for external api calling system?

What is the error message (if any)?

no any error right now

Information on your n8n setup

  • n8n version:1.22.4
  • Database (default: SQLite):default
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):cloud
  • Operating system:windows

But, as the webhook is dynamically generated so I don’t know what url I must use in the third party service. because the executions number is being changed on every run.

Hi @Kelash, n8n uses this execution ID to identify which execution to resume when receiving a webhook. It provides an expression that will always reference the correct URL for every single run {{ $execution.resumeUrl }} and which you can send to external systems.

And what do you suggest I should use for external api calling system?

This really is up to you. Even an email or Telegram message can do the job. Check out this workflow for an example:
