Previously, only the ticket buyer’s details were collected at checkout. Eventbrite now supports capturing individual attendee details after purchase using the Each attendee option in the event order form.

As a result, ticket data is now collected in two stages:

Stage 1 – The order is placed and ticket buyer details are captured.
Stage 2 – Individual attendee details are added by the buyer.

After Stage 1, Donorfy only receives ticket buyer details and the number of attendees. Individual attendee information is not yet available.

Understand the Impact on Donorfy Data

If you use the Each attendee option in Eventbrite, Donorfy processes data as follows:

A constituent is created for the ticket buyer, which holds the transaction.
A constituent is created for each attendee, which holds the event activity.

If the ticket buyer is also an attendee, an additional constituent may be created for them.

This behaviour means your total number of constituents may increase when events are active.

Handle Missing Attendee Details

If attendee details are not provided immediately after purchase:

A named constituent is created for the ticket buyer.
Attendees are created with placeholder identifiers:
- First name set to the Eventbrite Attendee ID.
- Last name set to the Eventbrite Event ID.

When attendee details are later added in Eventbrite, these constituent records are automatically updated in Donorfy with names, contact details, and consent preferences.

If duplicate constituents are created for the same person, Donorfy’s duplicate checker can resolve them.

⚠️ Important: Enabling automatic duplicate merging saves time by automatically merging constituents with a confidence score of 13 or higher.

Option 1: Show Attendees in Eventbrite but Only the Ticket Buyer in Donorfy

Use this option if you want detailed attendee management in Eventbrite but a single constituent in Donorfy.

In Eventbrite, enable Each attendee in the order form.
In Donorfy, open the relevant Campaign, then click the Eventbrite tab.
In the Activity section, set Create an Activity for each attendee to Yes.
In Exclude attendees holding these ticket types, enter the ticket types or add-ons to exclude.

This prevents additional constituents being created for excluded ticket types.

Option 2: Show Attendees in Both Eventbrite and Donorfy

Use this option if you want full attendee visibility in both systems.

In Eventbrite, enable Each attendee in the order form.
In Donorfy, open the relevant Campaign, then click the Eventbrite tab.
Set Create an Activity for each attendee to Yes.
Do not exclude standard ticket types, but optionally exclude non-attendance add-ons such as merchandise.

Some attendees may not provide personal details, and constituent numbers will increase.

Option 3: Show Only the Ticket Buyer in Both Systems

Use this option if attendee-level data is not required.

In Eventbrite, select Ticket Buyer in the order form setup.

No attendee-specific constituents or activities are created.
