Split In Batches

Process items in chunks — loop until the batch is empty.

When to use it

Large item arrays that would overwhelm a downstream API if sent all at once.

Writeup

How Split In Batches works

Process items in chunks — loop until the batch is empty. Large item arrays that would overwhelm a downstream API if sent all at once.

Step by step — how to wire it

01
Produce many items
Sheets read / HTTP list upstream.
02
Add Split In Batches
Set batch size (start small: 5–10).
03
Do work per batch
Batch → HTTP Request / HubSpot. Optional Wait for pacing.
04
Loop until done
Connect back into Split In Batches; use the done output for a final Slack summary.

How it functions

Batch size

You set how many items leave per loop (e.g. 10).

Loop pin

Done output vs loop — wire work on the batch, then back into Split In Batches until done.

Used for

Used for 1

Respecting API rate limits

Updating hundreds of Sheet rows safely

Used for 3

Paginated fan-out with a Wait between loops

Tips

Always handle partial failures inside the batch or one bad row aborts the loop.

Log batch index in Slack when debugging long runs.
