Create an order using the Orders API

That is the amount for the order total. You’ll now need to call CreatePayment with that order_id in the payment request. For example:

{
    "idempotency_key": "{{$guid}}",
    "autocomplete": true,
    "amount_money": {
        "amount": 2499,
        "currency": "USD"
    },
    "source_id": "cnon:card-nonce-ok",
    "order_id": "ZyoU5MBLBRBM5RqbJ82irlREqeKZY"
}
