Participant Custom Field — File

File

A file custom field accepts a publicly accessible URL pointing to the file.

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 "company_brochure=https://example.com/files/brochure-2025.pdf"

Notes

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

  • The value must be a publicly accessible URL — the platform will fetch the file from that URL

  • To clear the field, pass an empty value
