Update checkout

The Update checkout request will replace the entire checkout state. If you update the Checkout while the Checkout is visible, use the Checkout Client API's to invoke suspend before your operation and resume afterward. You can also update the objects individually: cart, shippingProperties, fees, reference, metadata.

Please note

Please note that this operation cannot be performed if the purchase is completed.

While the checkout is suspended, the checkout can be updated by calling the Checkout API from your backend as demonstrated in the following code:
