FAQ

Questions about Add Tag to Contact.

What does the Add Tag to Contact action do in ActiveCampaign?

Applies a tag to a contact — auto-creates the tag if it doesn't exist yet, which makes it forgiving for workflow setup but easy to fragment your tag taxonomy. Maintain a canonical tag list (in a Notion doc or workflow constant) to avoid "Customer", "customer", "Customers" all coexisting.

What inputs does Add Tag to Contact require?

Required: Contact ID, Tag 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 Add Tag to Contact support batch operations?

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