Field Mapping

Prerequisites

ActiveCampaign API URL format

https://youraccountname.api-us1.com

Go to Lists in ActiveCampaign, click on the list you want subscribers added to, and find the List ID in the URL or list settings page.

Go to your form's Settings tab, then Integrations. Scroll down to the ActiveCampaign section and:

ActiveCampaign integration settings panel in Flowqen

Flowqen creates a contact and then subscribes them to your list via two API calls:

POST{API_URL}/api/3/contact/sync

ActiveCampaign Contact Sync

{
  "contact": {
    "email": "jane@example.com",
    "firstName": "Jane",
    "lastName": "Smith",
    "phone": "+1234567890"
  }
}

POST{API_URL}/api/3/contactLists

ActiveCampaign List Subscribe

{
  "contactList": {
    "list": 1,
    "contact": 123,
    "status": 1
  }
}

Good to know

ActiveCampaign sync is fire-and-forget — it never delays or blocks the form submission.
If a contact with the same email already exists, their fields are updated (not duplicated).
Your API key is stored securely and never exposed to form submitters.
Contacts are automatically subscribed to the configured list with active status.
Works with ActiveCampaign Lite, Plus, Professional, and Enterprise plans.
