Webhook events

Webhook authentication

We've taken some steps to secure webhook communications, so you can always verify that a webhook event came from us and not from a malicious party.

Below are the steps you need to follow to verify that a webhook event came from Bridgecard.

STEP 1: Access your webhook secret from your dashboard (live_webhook_secret_key or test_webhook_secret_key depending on the environment)

STEP 2: Whenever you get a webhook event from Bridgecard, extract the x-webhook-signature header and decrypt it using your secret key (live_secret_key / test_secret_key depending on the environment)

$ pip install aes-everywhere

from AesEverywhere import aes256

# decryption
decrypted = aes256.decrypt('webhook secret', 'Bridgecard Secret Key')
decrypted = decrypted.decode()
print(decrypted)

$ npm install aes-everywhere

var AES256  = require('aes-everywhere');
// or
// import AES256 from 'aes-everywhere';

// decryption
var decrypted = AES256.decrypt('webhook secret', 'Bridgecard Secret Key')
console.log(decrypted);

$ composer require mervick/aes-everywhere

require '../../vendor/mervick/aes-everywhere/php/src/AES256.php';
use mervick\aesEverywhere\AES256;

$decrypt = AES256::decrypt('webhook secret', 'Bridgecard Secret Key')

import "github.com/mervick/aes-everywhere/go/aes256"

// decryption
decrypted := aes256.Decrypt("webhook secret", "Bridgecard Secret Key")

STEP 3: Compare the decrypted string with your webhook secret key from STEP 1. If they are the same, then it is a valid webhook event sent from us.
