In n8n, add an ActiveCampaign node (or use an HTTP Request node) and create credentials with your ActiveCampaign API URL and API key. You’ll find both in ActiveCampaign under Settings → Developer. Test the connection, then start with a trigger (Webhook, form, schedule, or “new contact”). From there, map fields like email, tags, and custom fields. If you use Flowpast templates, the connection step is usually the only setup before you run it.

Honestly, most of the busywork. You can auto-create or update contacts, apply tags, move deals in a pipeline, trigger sequences after purchases, and keep lists clean. Many teams also push leads to Google Sheets for reporting, send Slack alerts for high-intent signups, and route replies to Gmail. If you use OpenAI, you can score or summarize leads before they hit your CRM, so you focus on the right people.

Yes. You will need an ActiveCampaign account with API access so n8n can read and write your contacts, tags, and automations.

The biggest gotcha is data consistency: if your custom fields and tags aren’t standardized, automations can create duplicates or mis-segment contacts. API rate limits can also slow large imports, so batch updates are safer than blasting thousands of requests at once. Some events you expect to be “real-time” may require webhooks or polling, depending on your setup. Finally, be careful with looping logic (update triggers update) in n8n; add safeguards like “only update if changed.”
