How to assign a participant to an exhibitor team or update their role

Use this guide when you need to associate an existing participant with an exhibitor team, or update their role within that team.

What you'll need before starting

What you need	Where to get it
Exhibitor ID	`GET /api/v2/exhibitor/getList?event_id=` or `GET /api/v2/exhibitors/{eventId}/list`
Participant ID, External ID, or email	`GET /api/v2/account/get` or `GET /api/v2/participants/{eventId}/list`

Alternatively, use exhibitor_external_id if you already know the exhibitor's External ID — no lookup needed.

Request — assign to exhibitor team by exhibitor ID

Bash

curl -X POST "https://your-event-domain.com/api/v2/account/set" \
  -H "Authorization: Bearer your_api_key_here" \
  -F "event_id=7" \
  -F "id=12345" \
  -F "exhibitor_id=42" \
  -F "member_role=member"

Request — assign to exhibitor team by exhibitor External ID

Bash

curl -X POST "https://your-event-domain.com/api/v2/account/set" \
  -H "Authorization: Bearer your_api_key_here" \
  -F "event_id=7" \
  -F "id=12345" \
  -F "exhibitor_external_id=EXT-001" \
  -F "member_role=member"

Bash

curl -X POST "https://your-event-domain.com/api/v2/account/set" \

Response

JSON

{
  "code": 200,
  "errors": null,
  "data": {
    "id": 12345,
    "email": "john.doe@example.com",
    "status": "updated",
    "external_id": null,
    "info": ["Account match: id"],
    "errors": []
  },
  "response_id": "1700000000.12345"
}

Notes

member_role accepts member (access only) or admin (can edit the exhibitor profile and manage the team via the platform UI)
Each exhibitor has a maximum team member limit. If reached, the assignment fails with a non-fatal error in data.errors — the account is still updated
Exhibitor owner accounts cannot be modified via this endpoint
To remove a participant from an exhibitor team, see the "How to detach a participant from an exhibitor team" guide
