Hey everyone,

Basically, I want to recreate this Java Script code in [make.com](http://make.com) to get the webhook signature. The timestamp has already been handled “(Timestamp \* 1000)”, the hmac/webhook signature is the most important. The challenge is that I don’t want to use any external services like ‘custom JS’, etc. I just want to use [make.com](http://make.com)’s built-in functions and tools. I believe it’s possible, but you can correct me if I am wrong.

"const crypto = require(‘crypto’);

const SECRET\_KEY = ‘’  
const timestamp = Date.now();

const payload = {  
“campaign\_id”: “”,  
“webhook\_id” : “”,  
“leadData”: {  
“phoneNumber”: “”,  
“variables”: {  
“name”: “”,  
“monday\_id”: “”  
}  
}  
};

const signature = crypto  
.createHmac(‘sha256’, SECRET\_KEY)  
.update(timestamp + JSON.stringify(payload))  
.digest(‘hex’);  
return {signature, timestamp};"

Cheers,  
Jakub 🙂

Hey,

Thanks for answer, yeah I check those already, but I still have a problem to create something like this using functions “(timestamp + JSON.stringify(payload))”.
