I’d like to offer a gift instead of a discount and would expect the appropriate way to do that to be through the existing promo_code field on the public booking page. Unfortunately, it appears the promo code is currently limited to pricing/discount actions only. I need the promo_code value to be exposed to OwnerRez automations (triggers/webhooks/API) so that when a guest enters a code like RETURN_GUEST the booking can be automatically flagged for staff action (for example, add the tag Welcome Gift Needed) and a visible invoice line Valued Guest Welcome Gift — $0.00 can be applied without changing the booking total. If the promo_code field cannot be exposed, please provide the exact, supported steps to achieve this same outcome while keeping the promo-code entry on the public booking page, including any required configuration for discounts, surcharges, custom fields, triggers, and the exact menu paths and criteria to use.
