### <Icon icon="arrow-progress" iconType="solid" /> Order flow

The process of buying stablecoins on Rio is done through the following steps:

<Steps>
  <Step title="Register the deposit crypto address">
    Before creating an order, you need to register the crypto address that will receive the funds. This only needs to be done once per address-currency pair.

    <Card title="Go to create a new crypto address" icon="square-code" href="/api-reference/address/create-address" />
  </Step>

  <Step title="Create a quote">
    You can create as many quotes as necessary before creating an order.

    <Card title="Go to create quote endpoint" icon="square-code" href="/api-reference/quotes/create-quote" />
  </Step>

  <Step title="Create order">
    Once you are satisfied with a quote, you can create an order for the quoted amount.

    <Card title="Go to create order" icon="square-code" href="/api-reference/orders/create-order" />
  </Step>

  <Step title="Wait for the order to be ready to accept payment.">
    Poll the order or subscribe to our webhooks. Wait for the order to have a status of `awaitingPayment`.

    <Card title="Go to check order status" icon="square-code" href="/api-reference/orders/get-order" />
  </Step>

  <Step title="Pay for the order (skip if placing the order in our sandbox environment)">
    Please send the amount specified in the `amountFiat` field of the order object to the bank account specified in the `paymentInstructions` field of the order. Do not forget to send the reference.
  </Step>

  <Step title="Confirm payment (optional)">
    This final step is only necessary if the payment is made in USD outside of the United States, or if the order was placed in our sandbox environment and you want to simulate a successful payment.

    <Card title="Go to confirm payment" icon="square-code" href="/api-reference/bank-payments/check-bank-payment" />
  </Step>

  <Step title="Wait for funds">
    Rio will send the funds to your wallet in the next few minutes.
  </Step>
</Steps>
