The Create Payment Token (3DS) flow allows merchants to authenticate customers and tokenize their payment details. It is designed to facilitate strong customer authentication without disrupting the customer's checkout experience.
This guide provides step-by-step instructions and relevant code examples to help you integrate this payment flow using the CCBill Advanced Widget.
To perform 3DS authentication based on the customer's payment details, create a payment token and then use the token to charge the customer:
The following sequence diagram describes the flow for creating and charging payment tokens with 3DS authentication.
The following steps explain how to set up the CCBill Advanced Widget and create payment tokens with 3DS authentication.
To use the CCBill Advanced Widget, add the following preload link and script elements to your HTML page:
<link rel="preload" href="https://js.ccbill.com/v1.13.1/ccbill-advanced-widget.js" as="script"/>
<script type="text/javascript" src="https://js.ccbill.com/v1.13.1/ccbill-advanced-widget.js"></script>
The API version in this URI example is v1.13.1. Pay special attention to the version in the URI path, as the version number may be subject to change.
The Advanced Widget automatically extracts values from form fields. Depending on your integration, the required fields can be provided in three ways:
Using data-ccbill
data attributes is non-intrusive and provides more flexibility. It allows you to map form inputs directly without modifying existing id
attributes.
<form id="payment-form">
<input data-ccbill="firstName" />
<input data-ccbill="lastName" />
<input data-ccbill="postalCode" />
<input data-ccbill="amount" />
<input data-ccbill="country" />
<input data-ccbill="email" />
<input data-ccbill="cardNumber" />
<input data-ccbill="currencyCode" />
<input data-ccbill="expYear" />
<input data-ccbill="expMonth" />
<input data-ccbill="nameOnCard" />
<input data-ccbill="cvv2" />
</form>
If you cannot modify your HTML to include data-ccbill
attributes, use the default _ccbillId_
attributes instead. This method is less flexible because the field names must match CCBill's predefined format.
<form id="payment-form">
<input id="_ccbillId_firstName" />
<input id="_ccbillId_lastName" />
<input id="_ccbillId_postalCode" />
<input id="_ccbillId_amount" />
<input id="_ccbillId_country" />
<input id="_ccbillId_email" />
<input id="_ccbillId_cardNumber" />
<input id="_ccbillId_expYear" />
<input id="_ccbillId_currencyCode" />
<input id="_ccbillId_expMonth" />
<input id="_ccbillId_nameOnCard" />
<input id="_ccbillId_cvv2" />
</form>
If you prefer custom IDs, map them to corresponding input fields using the customIds
parameter in the Widget constructor.
<form id="payment-form">
<input id="custom_firstName_id" />
<input id="custom_lastName_id" />
<input id="custom_postalCode_id" />
<input id="custom_amount_id" />
<input id="custom_country_id" />
<input id="custom_email_id" />
<input id="custom_cardNumber_id" />
<input id="custom_currencyCode_id" />
<input id="custom_expYear_id" />
<input id="custom_expMonth_id" />
<input id="custom_nameOnCard_id" />
<input id="custom_cvv2_id" />
</form>
<script>
// map custom ids to relevant fields
const customIds = {
firstName: "custom_firstName_id",
lastName: "custom_lastName_id",
postalCode: "custom_postalCode_id",
amount: "custom_amount_id",
country: "custom_country_id",
email: "custom_email_id",

The CCBill RESTful API uses OAuth-based authentication and authorization. Use the frontend credentials (Merchant Application ID
and Secret Key
that are Base64 encoded) you received from Merchant Support to generate a frontend bearer token.
You must include this token in the Authorization header of API requests when creating payment tokens. Use the following example and adjust the necessary parameters to obtain a frontend bearer token:
curl -X POST 'https://api.ccbill.com/ccbill-auth/oauth/token' \
-u '[Frontend_Merchant_Application_ID]:[Frontend_Secret_Key]' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'grant_type=client_credentials'
String getOAuthToken() {
String credentials = Base64.getEncoder()
.encodeToString(("[Frontend_Merchant_Application_ID]" + ":" + "[Frontend_Secret_Key]")
.getBytes(StandardCharsets.UTF_8));
String requestBody = "grant_type=client_credentials";
HttpRequest request = HttpRequest.newBuilder()
.uri(URI.create("https://api.ccbill.com/ccbill-auth/oauth/token"))
.header("Authorization", "Basic " + credentials)
.header("Content-Type", "application/x-www-form-urlencoded")
.POST(HttpRequest.BodyPublishers.ofString(requestBody, StandardCharsets.UTF_8))
.build();
try {
HttpResponse<String> response = HTTP_CLIENT.send(request, HttpResponse.BodyHandlers.ofString());
return extractAccessToken(response.body());
} catch (IOException | InterruptedException e) {
e.printStackTrace();
return null;
}
}
<?php
function getOAuthToken() {
$url = "https://api.ccbill.com/ccbill-auth/oauth/token";
$merchantAppId = "[Frontend_Merchant_Application_ID]";
$secretKey = "[Frontend_Secret_Key]";
$data = http_build_query(["grant_type" => "client_credentials"]);
try {
$httpRequest = new HttpRequest();

$httpRequest->setMethod(HTTP_METH_POST);
$httpRequest->setHeaders([

$httpRequest->setBody($data);
$httpClient = new HttpClient();

Important Notes
The isScaRequired() function determines whether strong customer authentication is required before generating a payment token. The system checks the provided credit card number, merchant account number, subaccount, and currency code.
This method allows you to dynamically apply 3DS authentication only in instances when they are truly required.
Code Example
async function checkIfScaRequired() {
const widget = new ccbill.CCBillAdvancedWidget('your-application-id');
const scaRequiredResponse = await widget.isScaRequired(
"[Frondent_Access_Token]",
[Your_Client_Account_Number],
[Your_3DS_Client_Subaccount_Number]);
return await scaRequiredResponse.json();
}
The isScaRequiredForPaymentToken() function determines whether strong customer authentication (3DS) is required for a pre-existing Payment Token.
Merchants who have already stored payment information as a token (Payment Token ID) can use it to determine if SCA is required before processing a charge.
Code Example
async function checkIfScaRequired() {
const widget = new ccbill.CCBillAdvancedWidget('your-application-id');
const scaRequiredResponse = await widget.isScaRequiredForPaymentToken(
"[Frondent_Access_Token]",
"[payment_token_id]");
return await scaRequiredResponse.json();
}
Response Handling
The function automatically checks the transaction parameters to determine if strong customer authentication (SCA) is required:
The authenticateCustomer() function initiates an SCA flow to obtain 3DS results before executing a 3DS transaction and calling CCBill's RESTful API endpoint.
Code Example
async function authenticate() {
const widget = new ccbill.CCBillAdvancedWidget('your-application-id');
return await widget.authenticateCustomer(
"[Frondent_Access_Token]",
[Your_Client_Account_Number],
[Your_3DS_Client_Subaccount_Number]);
}
The authenticateCustomer()
function can also be used to perform strong customer authentication based on a pre-existing payment token.
Merchants who have already stored payment information as a token (paymentTokenID
) can use it to authenticate a customer before processing a charge.
Code Example
async function authenticate() {
const widget = new ccbill.CCBillAdvancedWidget('your-application-id');
return await widget.authenticateCustomer(
"[Frondent_Access_Token]",
[Your_Client_Account_Number],
[Your_Client_Subaccount_Number],
null, null,
"[payment_token_id]");
}
Response Handling
The function initiates the 3DS authentication flow and returns:
The createPaymentToken() function is the primary way to generate a payment token using the CCBill Advanced Widget. Invoke the function on the frontend after collecting and validating customer input and generating a frontend bearer token with your frontend credentials.
Code Example
async function createPaymentToken(scaRequired) {
const widget = new ccbill.CCBillAdvancedWidget('your-application-id');
const clientSubacc = scaRequired ? [Your_3DS_Client_Subaccount_Number] : [Your_Client_Subaccount_Number];
const paymentTokenResponse = await widget.createPaymentToken(
"[Frondent_Access_Token]",
[Your_Client_Account_Number],
clientSubacc
);
return await paymentTokenResponse.json();
}
Response Handling
The function creates the appropriate payment token based on the SCA requirement check and automatically validates all fields before generating a token:
The response may also have processing-related errors (such as token expiry). Visit the RESTful API Error Codes page for a comprehensive list of error codes.
Use the Payment Token ID and backend bearer token to charge a customer's credit card through a 3DS-secured payment flow. Generate a new backend bearer token using your Base64 encoded backend credentials.
Ensure the Payment Token passed the required 3DS authentication flow and the required 3DS values are collected.
