Exhibitor Custom Field — Select

Select

A select (dropdown) field allows a single selection from a predefined list of options.

Request

Bash

curl -X POST "https://your-event-domain.com/api/v2/exhibitor/set" \
  -H "Authorization: Bearer your_api_key_here" \
  -F "event_id=7" \
  -F "exhibitor_id=1200" \
  -F "stand_size=Large"

Notes

Pass the field's system name as the parameter key (e.g. stand_size)
The value must exactly match one of the configured dropdown options for that field
Only one value can be selected — passing a new value replaces the previous selection
Select fields behave identically to Radio Group fields at the API level — the difference is only in how they render on the form
