- Perform the payment by sending a
/paymentrequest with the following mandatory parameters:
-
userTokenIDamountcurrency- paymentOption.alternativePaymentMethod class containing:
paymentMethod: “apmgw_PayWithCrypto”
deviceDetailsclass containing:ipAddress

"merchantId":"<your merchantId>",
"merchantSiteId":"<your merchantSiteId>",
"clientRequestId":"<unique request ID in merchant system>",
"amount":"100",
"currency":"EUR",
"userTokenId":"<unique customer identifier in merchant system>",

/payoutusing Nuvei REST API 1.0 integration with the following steps:1. Register a
userTokenId.If there is no
userTokenId registered in the Nuvei system for the user, register by sending a /createUser request, including the following parameters:emailcountryCodefirstNamelastNamedateOfBirth
Example /createUser Request
{
"merchantId":"<your merchantId>",
"merchantSiteId":"<your merchantSiteId>",
"clientRequestId":"<unique request ID in merchant system>",
"userTokenId":"<unique user identifier in merchant system>",
"email":"[email protected]",
"countryCode":"<2-letter ISO country code>",
"firstName":"John",
"lastName":"Smith",
"dateOfBirth":"1975-01-01",
"timeStamp":"<YYYYMMDDHHmmss>",
"checksum":"<calculated checksum>"
}
Example /createUser Response
{
"userId":78403498,
"internalRequestId":552360538,
"status":"SUCCESS",
"errCode":0,
"reason":"",
"merchantId":"2439523627382132721",
"merchantSiteId":"224428",
"version":"1.0",
"clientRequestId":"20221108130736"
}
The request registers the userTokenId (userId) in the Nuvei system, which is needed to generate a UPO.
2. Create a UPO by sending an /addUPOAPM request that includes the following parameters:
userTokenId– The unique user identifier in your system.paymentMethodName: “apmgw_PayWithCrypto“apmDataclass containing:coindirect_ crypto_Addresscoindirect_ crypto_Currency
Example /addUPOAPM Request

"coindirect_crypto_Address": "<your cryptoAddress>",
"coindirect_crypto_Currency": "<your cryptoCurrency>"
},
"billingAddress":{
"country":"FR",
"email":"[email protected]",
},
"timeStamp":"<YYYYMMDDHHmmss>",
"checksum":"<calculated checksum>"

The request returns an encrypted userPaymentOptionId (UPO) representing the user APM account details.
Example /addUPOAPM Response
{
"userPaymentOptionId":83458468,
"internalRequestId":553078068,
"status":"SUCCESS",
"errCode":0,
"reason":"",
"merchantId":"2439523627382132721",
"merchantSiteId":"224428",
"version":"1.0",
"clientRequestId":"20221109154215"
