First, make sure you have a credit card on file in the app. Then, look in “Promos and Credits” under Settings to see your available credits. If you have a promo code, enter it in the field provided. When you book a ride in the app, set your credit card on file as your payment method and pay for the ride through the app. Please note that promo codes and credits can only be redeemed on rides that are booked and paid for successfully through the app with a valid credit card. They cannot be redeemed using any other payment method.
Credits cannot be used for rides that are hailed on the street and paid for using the Curb app.
At the end of your ride, any credits you have will be automatically deducted from the final total (fare, fees, and tip).
