Connect ActiveCampaign to HeySummit when you want attendee registrations to be sent to an ActiveCampaign list for your email campaigns, automations, and CRM follow-up.
Get your ActiveCampaign API details
Log in to ActiveCampaign.
Go to Settings > Developer.
Copy your API URL and API Key.
The HeySummit API URL field expects the API base URL shown in your ActiveCampaign Developer settings. Use that exact host rather than guessing it from your account name. Keep the API key private. See ActiveCampaign's current API guide. If ActiveCampaign shows a URL ending in /api/3, leave that final /api/3 part out when you paste it into HeySummit.
Connect ActiveCampaign in HeySummit
In HeySummit, go to Event Settings > Integrations & Developer > Integrations.
Click Add.
Choose ActiveCampaign.
Paste your ActiveCampaign API URL and API key.
After the credentials are accepted, select the ActiveCampaign list that should receive attendees. Optionally configure Contact Tagging, Custom Registration Field Mappings, and Other Field Mappings.
Save the integration.
What HeySummit syncs
After ActiveCampaign is connected, HeySummit automatically syncs eligible completed registrations for your event. Attendees are added to the ActiveCampaign list you selected. If a contact with the same email already exists in ActiveCampaign, HeySummit updates the existing contact instead of intentionally creating a duplicate. If contact tagging is enabled, HeySummit applies the configured tag when the attendee is synced. You can use {event_title} and {event_hash} as placeholders in the tag value. You can also map HeySummit registration questions and other attendee fields to ActiveCampaign fields. Custom registration answers and additional fields that are not mapped will not be synced. If you connected ActiveCampaign after attendees had already registered, open the integration's actions menu and choose Resync Attendees. HeySummit will queue existing event attendees to be synced with ActiveCampaign.
