How to bulk remove participants except specific ones

Use this guide when you need to remove all participants from an event but want to preserve specific accounts — for example, keeping admin or test accounts while clearing everyone else.

Prerequisites

Your API key
The event_id of the event
The internal account IDs of the participants to keep (the except list)

Request — detach all except specific accounts

Bash

curl -X DELETE "https://your-event-domain.com/api/v2/account/deleteBulk?event_id=7&from_event=true&except=101,202,303" \
  -H "Authorization: Bearer your_api_key_here"

Request — permanently delete all except specific accounts

Bash

curl -X DELETE "https://your-event-domain.com/api/v2/account/deleteBulk?event_id=7&except=101,202,303" \
  -H "Authorization: Bearer your_api_key_here"

Response

JSON

{
  "code": 200,
  "data": {
    "id": "104,105,106,107",
    "status": "Accounts removed from event"
  },
  "response_id": "1700000000.12345"
}

The accounts listed in except are not included in the id list and are unaffected.

Notes

except accepts a comma-separated list of internal account IDs only — not emails or External IDs
Use from_event=true to detach only, or omit it to hard delete
The except list is subtracted before processing — those accounts are skipped entirely
