Wallet Order Reservations are required before processing cards. A successful Wallet Order Reservation will return a URL of the hosted widget which can be presented to your users and a reservation identifier if you choose to use a white-label card processing API solution.
To quote a different
sourceCurrency please set it to a supported presentment currency (e.g. USD, GBP, EUR, etc).
There are two ways to specify the
amount(will always be the fiat amount without fees included, so
amountIncludeFeesshould NOT be passed in the request)
destAmount(fiat/crypto amount respectively, use only one, not both)
sourceAmount/destAmount is specified,
amountIncludeFees is mandatory. This informs whether the amount has fees already included or not.
amountIncludeFees = false
Fees are added on top: $100 + fees will be charged to the user. The user receives the full $100 in value.
amountIncludeFees = true
Fees will be subtracted from the amount: $100 - fees will be sent to the user's wallet. The user receives the amount less the fees.
