Follow these steps to perform a payment using Nuvei REST API integration:

1. Generate a sessionToken

Press here for details.

2. Send a /payment Request

Perform the payment by sending a /payment request with its mandatory parameters including:

• userTokenId
• amount
• currency
• paymentOption.alternativePaymentMethod block containing:
  • paymentMethod: “apmgw_OKTO_CASH“
• deviceDetails block containing: ipAddress
• billingAddress block containing: firstName, lastName, country, email
• userDetails block containing: firstName, lastName, country, email

For customers in Romania, the following additional parameters must be sent in the userDetails block:
firstName, lastName, dateOfBirth, email, phone, and identification.

Example /payment Request

{
  "sessionToken":"<sessionToken from getSessionToken>",
  "merchantId":"<your merchantId>",
  "merchantSiteId":"<your merchantSiteId>",
  "clientRequestId":"<unique request ID in merchant system>",
  "amount":"200",
  "currency":"RON",
  "userTokenId":"<unique customer identifier in merchant system>",
  "clientUniqueId":"<unique transaction ID in merchant system>",
  "paymentOption":{
    "alternativePaymentMethod":{
      "paymentMethod":"apmgw_OKTO_CASH"
    }
  },
  "deviceDetails":{
    "ipAddress":"<customer's IP address>"
  },
  "billingAddress":{
    "firstName": "John",
    "lastName": "Smith",
    "country":"RO",
    "email":"john.smith@email.com",
  },
  "userDetails":{
    "firstName": "John",
    "lastName": "Smith",
    "country":"RO",
    "email":"john.smith@email.com"
  },
  "timeStamp":"<YYYYMMDDHHmmss>",
  "checksum":"<calculated checksum>"
}

After the transaction is processed, the user receives a Direct Merchant Notification (DMN) (sent to the notificationUrl parameter you can provide in the request) that includes the result of the transaction.

Follow these steps to perform a payment using Nuvei Web SDK integration.

1. Initiate a Session

Before you can submit payment using the client-side Nuvei Web SDK, you need to send the /openOrder API call.

2. Initialize the Web SDK

Instantiate the Web SDK with the sessionToken received from the server call to /openOrder.

3. Create an APM Payment

Send a createPayment() request with its mandatory parameters including:

• paymentOption.alternativePaymentMethod block containing:
  • paymentMethod: “apmgw_OKTO_CASH“
• deviceDetails block containing: ipAddress
• billingAddress block containing: firstName, lastName, country, email
• userDetails block containing: firstName, lastName, country, email

For customers in Romania, the following additional parameters must be sent in the userDetails block:
firstName, lastName, dateOfBirth, email, and identification.

Example createPayment() Request

sfc.createPayment({
  sessionToken: "<sessiontoken>",
  paymentOption: {
    alternativePaymentMethod: {
      paymentMethod: "apmgw_OKTO_CASH",
    }     
  },
  deviceDetails  : {
    ipAddress  : "<customer's IP address>"
  },
  billingAddress  : {
    firstName: "John",
    lastName: "Smith",
    country  : "RO",
    email:"john.smith@email.com"
  },
  userDetails  : {
    firstName: "John",
    lastName: "Smith",
    country  : "RO",
    email:"john.smith@email.com"
  },
}, function(res) {
  console.log(res);
});

After the transaction is processed, the user receives a Direct Merchant Notification (DMN) (sent to the notificationUrl parameter you can provide in the request) that includes the result of the transaction.
