Fixed Rate Order Guide

This section is described in detail because a fixed rate requires additional steps to make it work. With a floating rate, you send a request for an endpoint and do not specify anything additional.

In order to work with a fixed rate, you need to specify the value of the rateType field

Let's make an Estimate amount request

{
    "from": "CARDUAH",
    "to": "USDTTRC20",
    "toNetwork": "TRX",
    "fromAmount": 3000,
    "rateType": "FIXED"
}

We received a response from the API:

{
    "extraFromFee": 0.0,
    "extraToFee": 0.0,
    "from": "CARDUAH",
    "fromAmount": 3000.0,
    "fromFee": 6.0,
    "fromNetwork": null,
    "fromRate": 37.45992,
    "fromRevenueShare": 12.0,
    "rateType": "FIXED",
    "side": "BUY",
    "to": "USDTTRC20",
    "toAmount": 78.605082,
    "toFee": 1.0,
    "toNetwork": "TRX",
    "toRate": 1,
    "toRevenueShare": 0.0
}

Here we have two additional fields rateId and rateIdExpirationTimestamp

rateId - ID of the fixed rate which you will pass when creating an order.

rateIdExpirationTimestamp - time when fixed rate will expire.

Now we need to create order #create-a-new-order.with field rateId from estimate.
