How can we add rewards to checkout-api. There are ‘Read-only’ fields (reward, reward-tier-id) ([POST /v2/locations/{location\_id}/checkouts - Square API Reference](https://developer.squareup.com/reference/square/checkout-api/create-checkout) - order attributes. I found some hint in [How can I generate the Checkout URL for existing Order](https://developer.squareup.com/forums/t/how-can-i-generate-the-checkout-url-for-existing-order/3351) where it asks you to use calculate (where you can propose rewards) and copy the order into the checkout-api Another hint is to create the order , add the rewards using qttps://developer.squareup.com/reference/square/loyalty-api/create-loyalty-reward with the order\_id, then retrieve the order, and include the order (as a new order) into checkout. Both of these seem difficult and awkward, and may not work. Is there an easier way? Thanks -Vasan ---

👋 With the Checkout API you will need to use [CalculateOrder](https://developer.squareup.com/reference/square/orders-api/calculate-order) first then create the checkout with that calculated order. 🙂 ---

Not sure this works. Calculate order does create an order with rewards, but cannot put that into the checkout API ([POST /v2/locations/{location\_id}/checkouts - Square API Reference](https://developer.squareup.com/reference/square/checkout-api/create-checkout)) because many ‘read-only’ fields are in there which cannot be specified. If you remove them, then the rewards are not appiled. It looks like the checkout-api wants to recalculate the order, but is missing the ‘proposed\_rewards’ parameter (which is there in calculate order). It looks like there may be some other way or… ---

Hooray… Got it to work after deleteing read-only fields, and ‘redundant info’ (like name if catalog\_object\_id is there) and responded to all error messages, and it did work (Thx) New problem: On the checkout page, it applies the discount(or reward), but does no indicate clearly that it did: ![image](https://global.discourse-cdn.com/square/original/1X/988c7d91c96990f74daf1a5ae9ba6eb6ee5419c4.png) In that image note that 3.95 for the Baklava is not added to the total, but the display is not clear that it happened. ---

What is the `order_id` for that checkout? ---
