Participant Custom Field — Radio Group

Radio Group

A radio group field allows a single selection from a predefined list of options.


Request

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 "dietary_preference=Vegetarian"

Notes

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

  • The value must exactly match one of the configured options for that field

  • Only one value can be selected — passing a new value replaces the previous selection
