Participant Custom Field — Checkbox

Checkbox

A checkbox field is a single boolean toggle — checked or unchecked.

Request — check the box

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 "agree_to_terms=1"

Request — uncheck the box

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 "agree_to_terms=0"

Notes

  • Pass the field's system name as the parameter key (e.g. agree_to_terms)

  • 1 = checked, 0 = unchecked

  • This is a single checkbox (boolean toggle) — not to be confused with Checkbox Group, which allows multiple selections from a list
