Hello dear developers, | |
I ported this function for JVZoo IPN verification from PHP one at | |
(https://jvzoo.zendesk.com/hc/en-us/articles/206456857-JVZIPN-How-to-create-your-own-integrated-script) and | |
wanted to share that with all fellow devs. | |

// the requires | |
var utf8 = require('utf8'); | |
const crypto = require("crypto"); | |
// proper sha1 generator | |
function sha1(data) { | |
return crypto.createHash("sha1").update(data, "binary").digest("hex"); | |
} | |
// Function to be exported ;) modules.export .... | |
function isJvzipnVerified(callbackResponse) { | |
let secretKey = "YOUR_KEY"; | |
let pop = ""; | |
let ipnFields = []; | |
for (let key in callbackResponse) { | |
if (key == "cverify") { | |
continue; | |
} else { | |
ipnFields.push(key); | |
} | |
} | |
ipnFields.sort(); | |
for (let key in ipnFields) { | |
pop += callbackResponse[ipnFields[key]] + "|"; | |
} | |
pop += secretKey; | |
calcedVerify = sha1(utf8.encode(pop)); | |
calcedVerify = (calcedVerify.substr(0,8)).toUpperCase(); | |
return calcedVerify == callbackResponse.cverify; | |
