FAQ

Questions about Update Iterable User.

What does the Update Iterable User action do in Iterable?
Upserts user data fields (plan, country, signup_date, lifetime_value). The state-update hook for keeping audience segmentation accurate.
What inputs does Update Iterable User require?
Required: Email. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Iterable returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Update Iterable User support batch operations?
Yes. Run Update Iterable User inside a Loop node to process arrays. Tiny Command handles Iterable's rate limits automatically so you don't have to throttle manually.
