Airbnb does not currently have a built-in feature for creating coupons or discount codes. However, you can offer discounts by using the Special Offer feature, adjusting the price of a booking, or issuing a partial refund through the Resolution Center. These options allow you to provide a customized rate for your guests directly within the platform.
Welcome to the community! Is there a particular reason you wanted to create a coupon for one of your guest? Perhaps if you tell us more, we might be able to offer alternative suggestions.
In the meantime, in addition to the information Alicia shared, I wanted to include the official Airbnb feedback form here, so you can share your suggestion directly with Airbnb. 🙂
