How to bulk delete all participants permanently

Use this guide when you need to permanently remove all participant accounts from the system for a given event.

⚠️ This is a hard delete. All matched accounts are permanently removed from the system. This cannot be undone. If you only need to unregister participants from the event while keeping their accounts, use the "How to bulk detach all participants from an event" guide instead.

Prerequisites

Your API key
The event_id of the event

Request

Bash

curl -X DELETE "https://your-event-domain.com/api/v2/account/deleteBulk?event_id=7" \
  -H "Authorization: Bearer your_api_key_here"

Response

JSON

{
  "code": 200,
  "data": {
    "id": "101,102,103,104",
    "status": "Accounts deleted from event"
  },
  "response_id": "1700000000.12345"
}

Notes

Omitting from_event (or passing from_event=false) triggers a hard delete
The id field contains a comma-separated list of all permanently deleted account IDs
If the event has no participants, a 400 error is returned
