How to detach a participant from an event

Use this guide when you need to unregister a participant from a specific event while keeping their account in the system. This is useful when a participant cancels their attendance but may attend future events.

Prerequisites

Your API key
The participant's internal id, email, or external_id
The event_id to detach them from

Request — detach by internal ID

Bash

curl -X DELETE "https://your-event-domain.com/api/v2/account/delete?id=12345&from_event=true&event_id=7" \
  -H "Authorization: Bearer your_api_key_here"

Request — detach by email

Bash

curl -X DELETE "https://your-event-domain.com/api/v2/account/delete?email=john.doe@example.com&from_event=true&event_id=7" \
  -H "Authorization: Bearer your_api_key_here"

Request — detach by External ID

Bash

curl -X DELETE "https://your-event-domain.com/api/v2/account/delete?external_id=EXT-00123&from_event=true&event_id=7" \
  -H "Authorization: Bearer your_api_key_here"

Response

JSON

{
  "code": 200,
  "data": {
    "id": 12345,
    "status": "Account removed from event with ID 7 succesfully"
  },
  "response_id": "1700000000.12345"
}

Notes

The account is not deleted — it remains in the system and can be re-registered for future events
from_event=true and event_id must both be present for a detachment
If the account is not registered for the specified event, a 400 error is returned
To permanently delete an account, see the "How to permanently delete a participant" guide
