Affinity Integration

How it works

Gatsby syncs guest RSVP and attendance information directly to your Affinity CRM. You specify a list or global Affinity field, and Gatsby handles the data transfer automatically whenever guests interact with your events.

What data appears in Affinity

You’ll find three fields in your specified list or global scope, depending on how you configured the integration. Field names will match your Affinity field mapping selection.

Columns in Affinity are populated with the event name

Guest List field

Shows each event where a guest appeared on the guest list, regardless of their RSVP or attendance status.

---

RSVP field

Shows each event where a guest accepted their invitation.

---

Attendance field

Shows each event where a guest was checked in.

When data syncs

Gatsby writes information to Affinity automatically when guests RSVP, check in, or get added to a guest list. Changes appear in Affinity almost instantly.

Event tags (Power Users)

Power Users can create tags and apply them to events in Gatsby. When guests check in to tagged events, you can see which events under which tags each guest attended in your Affinity records.

Once connected, Gatsby will automatically transfer contacts and their RSVP data to your Affinity. The data appears as tags in your Affinity columns.

List to List Syncing

Gatsby allows you to connect a Global Affinity list to a Gatsby Guest List for real-time, bidirectional synchronization. The lists stay perfectly in sync—when someone is removed from Affinity, they’re automatically removed from Gatsby, and vice versa.

This feature is particularly valuable for IR teams working primarily in Affinity or when you want to build your guest list in Affinity and sync it to an event in Gatsby.

How it works

• Bidirectional sync: Changes in either platform automatically reflect in the other
• Real-time updates: Additions and removals happen instantly
• Event-specific configuration: Each event can connect to a different Affinity list

Setting up List to List syncing

To connect an Affinity list to your Gatsby event:

1. Edit your event details in Gatsby
2. Select the Affinity list from the dropdown menu in the event settings
3. Save your changes - the sync will begin immediately

Once configured, your Gatsby guest list will automatically stay in sync with the selected Affinity list.

FAQ

Is this a two-way data sync?

RSVP, attendance data, and a guest’s name and email address flows from Gatsby to Affinity only. List to List syncing provides bidirectional synchronization of guests’ names, emails, and presence on the guest list.
