Question

Why is the domain_id field (or other Data Graph fields) not available in the profile exits event when mapping a Segment Audience to a Webhook destination, even though it is available in the profile enters event?

Answer

In Segment Audiences, the profile exits event is designed to be minimal and only includes the entity_id by default. Additional Data Graph fields, such as domain_id, are not exposed in the profile exits event payload. This is an intentional product limitation to optimize performance and reduce payload size. As a result, only the entity_id is available when a profile leaves an audience, while custom fields like domain_id are available in the profile enters event.

Currently, there is no supported way to include additional Data Graph fields in the profile exits event. If your use case requires this functionality, you can submit a feature request through your Segment Customer Success Manager or feedback channels.

Additional Information 

• This limitation has been reported by other customers and is under consideration by the product team.
• No error message is shown; the field is simply not present in the exits event payload.
