Merge data

Bring branches back together and combine data from two inputs.

Merge combines items from two inputs. It runs as soon as at least one input has data.

Modes

ModeResult
AppendAll items from input 1, then all items from input 2
By positionItem 1 with item 1, item 2 with item 2…, merged into one item each
By keyItems whose key fields match (for example email and customer_email) merged into one item

Common uses

  • Rejoin branches: after an IF, connect both branches into a Merge in Append mode to continue with all items.
  • Enrich data: fetch orders on one branch and customers on the other, then merge by key on the customer ID.
