FAQ

Questions about Update Contact.

What does the Update Contact action do in ActiveCampaign?

Updates standard fields and custom fields on an existing contact by ID. Partial updates supported — only the passed fields change, others stay untouched. For "enrichment from external source → write back to AC" workflows where you're augmenting with firmographic data after the initial signup.

What inputs does Update Contact require?

Required: Contact ID. 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 ActiveCampaign 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 Contact support batch operations?

Yes. Run Update Contact inside a Loop node to process arrays. Tiny Command handles ActiveCampaign's rate limits automatically so you don't have to throttle manually.
