This endpoint is the starting point for initializing all Wyre transfers - moving and/or exchanging currency or tokens.
Auto Confirmation Settings
When autoConfirm is false, the returned transfer details can be used to present associated fees to the user before confirmation. The rates are locked for 15m if fiat-fiat or no exchange, 10m for crypto exchanges (including stablecoins). Unconfirmed transfers will expire after this locked period. If the transfer expires you'll have to reissue the transfer request and confirm the new transfer.
You may also instead automatically confirm the transfer by supply autoConfirm=true to skip the followup price confirmation.
Constructing the Transfer Request
The Transfer API offers flexibility in the intents that it accepts. There are three primary constructs that together create this functionality:
Source and Destination
The source of the transfer is the system from which funds are being pulled, while the dest is, somewhat unsurprisingly, the final destination of the funds. These parameters are SRNs and can be different types - accounts, payment methods, wallets, or blockchain addresses.
Eligibility varies across these types as well as between specific instances for usage as source or destination. e.g. a bitcoin address may be used (currently) only as a destination, while some payment methods may be able to be used for either source or destination.
Movement vs Exchange
The API offers two paramters, sourceCurrency and destCurrency, which collectively control the exchange behavior of the transfer.
If only sourceCurrency is supplied, or both are supplied and are identical, the transfer will perform no exchange and the currency will remain in its original form.
If the two are different, then an exchange is performed to convert the sourceCurrency taken from the source to the destCurrency.
Totals
There are three common ways to express the numeric totals involved in your Transfer:
Amount of money to process
You indicate the amount to move or convert. Fees are added on top of your indicated subtotal, and the resulting final total is withdrawn/requested from the source.
In this case, specify only sourceAmount, and amountIncludesFees will default to false.
Total to withdraw
You want to indicate the total amount that will be withdrawn/requested from the source, inclusive of fees.
In this case, specify sourceAmount and also specify amountIncludesFees=true.
Total to arrive
You want to indicate the total amount that will hit the destination. The system will compensate in fees and exchange rate to accomplish it.
In this case, specify only destAmount, and amountIncludesFees will default to false.
Transfer Fields
| Field | Description |
|---|---|
exchangeRate | The quoted exchange rate for the transfer expressed as a multiplier, such that:sourceAmount * exchangeRate = destAmountThis rate may vary on shallow markets |
totalFees | The total fees will always be represented in the source currency. To convert totalFees to the destination currency, multiply it by the exchange rate. Note that this object includes all Wyre fees and miner fees if applicable. |
sourceAmount | the total amount of funds, incl. fees, used in processing this transfer |
destAmount | the total amount of funds that should be received by the destination |
Using Masquerade
If you're requesting a transfer for a sub-account because you're acting on behalf of the sub-account holder, you will need to use the masqueradeAs URL parameter.
