Before you can start creating orders, you need to create a bulk payment that you will use to pay for multiple orders at once. This needs to be done each time you want to create a new set of orders that a single payment will cover.

Assuming you want to sell USDC (Polygon) in Mexico, then you would pass the following fields in the request body:

{
  "crypto":"SOL_USDC_PTHX",
  "country":"MX"
}

Create a quote for the order. Assuming you would like to sell USDC (Solana) for MXN, you would provide the following fields in the body:

  {
    "side":"sell",
    "crypto":"SOL_USDC_PTHX",
    "fiat":"MXN",
    "country":"MX"
  }

Additionally, you need to specify the order size. You can either specify how much USDC (Solana) you would like to sell, like this (selling $150,000 USDC (Solana)):

"amountCrypto":150000

Or you can alternatively specify the amount of MXN you would like to receive, like this (receiving $1,000,000 MXN):

"amountFiat":1000000

Once you are satisfied with a quote, you can create an order to book the trade. Assuming you would like to continue with the quote you created in the previous step to sell USDC (Solana) for MXN, then you would provide the following body:

{
    "quoteId":"{{QUOTE_ID_FROM_PREVIOUS_RESPONSE}}",
    "payoutBankAccountId":"{{ID_OF_MXN_BANK_ACCOUNT}}",
    "bulkCryptoPaymentId":"{{ID_FROM_RESPONSE_OF_SETP_1}}",
    "usePreSettlement":true
}

Before settling this order, you can create other orders with the same bulkCryptoPaymentId. By doing so, you will add them to the bulk crypto payment and thus will only need to make one payment to settle multiple orders.

After creating an order, it will update its status field as it goes through its lifecycle. Once the status field is equal to awaitingPayment, then the order is ready to receive payment. When all of the orders you added to the bulk crypto payment are in this status, then you can get ready to send the payment.

Retrieve payment amount and the deposit address specified by the bulk payment you created earlier.

Send the USDC (Solana) specified by the amount field of the bulk crypto payment to the address specified by the depositAddress field of the bulk crypto payment. Make sure to send the exact amount to avoid delays.

Since the funds have been pre-settled, the order is now complete. You will be able to view the details of the payout by inspecting the payoutsSent field of the order.
