How to assign child exhibitors to a parent

Use this guide when you need to link one or more exhibitors as children of a parent exhibitor. There are two approaches — choose based on which side of the relationship you have access to.

What you'll need before starting

What you need	Where to get it
Parent exhibitor ID	`GET /api/v2/exhibitor/getList?event_id=` or `GET /api/v2/exhibitors/{eventId}/list`
Child exhibitor ID(s)	Same as above

The parent exhibitor must already have is_parent_exhibitor=true set. See the "How to create a parent exhibitor" guide.

Approach 1 — Update the parent with the list of children

Pass all child exhibitor IDs as a comma-separated list in children_exhibitors.

Bash

curl -X POST "https://your-event-domain.com/api/v2/exhibitor/set" \
  -H "Authorization: Bearer your_api_key_here" \
  -F "event_id=7" \
  -F "exhibitor_id=1200" \
  -F "children_exhibitors=1201,1202,1203"

⚠️ children_exhibitors replaces the existing child list on every request. Always include the full list of intended children.

Approach 2 — Update each child with the parent ID

Pass the parent's internal ID in parent_exhibitor_id on each child.

Bash

curl -X POST "https://your-event-domain.com/api/v2/exhibitor/set" \
  -H "Authorization: Bearer your_api_key_here" \
  -F "event_id=7" \
  -F "exhibitor_id=1201" \
  -F "parent_exhibitor_id=1200"

Each request assigns that child to the parent. Existing children from previous requests are not affected.

Notes

An exhibitor cannot be both a parent and a child
To verify the hierarchy, use GET /api/v2/exhibitor/get and inspect child_exhibitors and parent_exhibitor_id
