update_custom_field

Edit an existing custom-field definition's label, required flag, select options, or display order. The field's type and key cannot be changed after creation — to change the type, archive this field with delete_custom_field and create a new one. Pass only the fields you want to change. Identify the field by its id (from list_custom_field_definitions). You don't pass an agency — it comes from your credentials.
