The Merge Node is one of the key building blocks of non-trivial n8n workflows — and one of the most commonly misunderstood. In this episode I take it apart with practical examples.
What you will learn
- How to join different workflow branches at a single point.
- The differences between the Append, Combine and Choose Branch modes and when to use each.
- How Merge pairs up items coming from its two inputs.
- How to handle data conflicts (clash) when both inputs carry fields with the same names.
Why it matters
Without understanding the Merge Node it is hard to build workflows that branch out and come back together — and that is standard in any larger automation: enriching data from two sources, combining results of parallel API calls, or merging data after conditional routing.
