What it does

This n8n template shows how to start several sub-workflows at the same time and wait until all of them report back. Each run gets a unique identifier and a resume URL, and a wait-for-all loop checks whether every run has finished before the parent workflow continues. It is a design pattern, so you adapt the input data to your own process.

Use cases

  1. 01Process a batch of documents in parallel
  2. 02Continue only when every sub-workflow has finished
  3. 03Track each run with its own identifier
