Testing Webhook signing

You can use DefaultSignatureValidator.isValid() to validate incoming webhook.


const {DefaultSignatureValidator} = require("chargily-epay-js/lib/Webhook");
const express = require('express');
const app = express()
const port = 3000
app.use(express.json());

app.post('/webhook-validator', (req, res)=>{
  let signature = req.header('Signature')

   let rs = DefaultSignatureValidator.isValid(
            signature, 
            process.env.CHARGILY_APP_SECRET,
            req.body) // return boolean
   
   res.send(rs)
 })
