I have started from below code but couldnt move forward. getting {"response": {"rmsg": "Authentication Failed"}} for below code.
import CryptoJS from "crypto-js";
// Your CyberSource credentials
const merchantId = "unf_myqadv_test";
const keyId = "xxxx-xxxx-4e7b-8883-xxxxxxxx";
const secretKey = "F2HVMyitPsFwfWeoDInoQsEj/XXXXXXXXXXXX=";
const generateSignature = async (method: string, requestBody: string) => {
const date = new Date().toUTCString();
const digest = `SHA-256=${CryptoJS.SHA256(requestBody).toString(CryptoJS.enc.Base64)}`;
// Use the actual endpoint path in the signature string
const signatureString = `(request-target): ${method.toLowerCase()} /pts/v2/capture-contexts\nhost: apitest.cybersource.com\ndate: ${date}\ndigest: ${digest}`;
const signature = CryptoJS.HmacSHA256(signatureString, secretKey).toString(
CryptoJS.enc.Base64
);
const headers = {
"v-c-merchant-id": merchantId,
Date: date,
Host: "apitest.cybersource.com",
Digest: digest,
Signature: `keyid="${keyId}", algorithm="HmacSHA256", headers="(request-target) host date digest", signature="${signature}"`,
"Content-Type": "application/json",
};
return headers;
};
interface PaymentFormData {
email: string;
amount: string;
currency: string;
}
export const retrieveCyberSourceForm = async (data: PaymentFormData) => {
const requestBody = JSON.stringify({
amount: data.amount,
currency: data.currency,
email: data.email,
});
const headers = await generateSignature("POST", requestBody);
try {
const response = await fetch(
{
method: "POST",
headers: headers,
body: requestBody,
}
);
const jsonResponse = await response.json();
console.log("CyberSource Response:", jsonResponse);
return jsonResponse;
} catch (error) {
console.error("Error retrieving CyberSource form:", error);
throw error;
}
};
