Participant Custom Field — Text and Text Area

Text / Text Area

Text and text area fields accept free-form string values. Text fields are single-line; text area fields accept multi-line input. Both are handled identically at the API level.

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 "special_requirements=Wheelchair accessible seating required"

Notes

Pass the field's system name as the parameter key (e.g. special_requirements)
The value is a free-form string — there is no option matching
To clear the field, pass an empty value
