Adding a merchant's delivery methods via the API

You can use the API in Yandex Pay to add any merchant's delivery methods.

To show the merchant's delivery methods, pass the shipping object in the order/render response.

Courier delivery

To show the delivery options, add the COURIER type to shipping.availableMethods. Yandex Pay will execute the order/render request with the optional shippingAddressparameter, which will include the user's delivery address. Based on the delivery address, the merchant's backend should calculate the delivery options for the provided address and return a list in availableCourierOptions.

If the merchant doesn't deliver to the address provided, instead of the availableCourierOptions list, the backend should return courierOptionsError with the DELIVERY_NOT_AVAILABLE_FOR_ADDRESS value. If the merchant's backend fails to process some addresses, it must return the WRONG_ADDRESS code for them.
