Join parallel branches back into one stream before the next decision.
When to use it
You forked the graph and need both results on one item (or paired items) before continuing.
Writeup
Join parallel branches back into one stream before the next decision. You forked the graph and need both results on one item (or paired items) before continuing.
Step by step — how to wire it
01
Fork from one node
Webhook → HTTP Enrich and Webhook → Set Profile (two outputs).
02
Add Merge
Both branches into Merge. Mode Combine → Combine by Position.
03
Continue once
Merge → IF / HubSpot / Respond — one path again.
04
Check item counts
If branches emit different lengths, switch combine strategy or you’ll mis-pair rows.
How it functions
Modes
combine + combineByPosition pairs inputs by index — common for 1:1 enrich patterns.
Waits for inputs
Merge does not continue until both connected branches delivered (per mode).
Used for
Used for 1
HTTP enrich + Set profile → single IF VIP
Used for 2
Waiting for two APIs before Respond
Used for 3
Recombining split paths
Tips
Don’t Merge if branches are independent notifications — parallel ends are fine.
Name inputs Input 1 / Input 2 clearly on the canvas.
