Identity validation helps ensure that the conversations between your customers and support agents are private. It also helps with disallowing impersonation.
Identity validation can be enabled by generating an HMAC.
The key used to generate HMAC for each web widget differs and can be copied from Inboxes -> Settings -> Configuration -> Identity Validation -> Copy the token shown there.
You can generate HMAC in different languages, as shown below.
Generate HMAC
PHP
<?php
$key = '<webwidget-hmac-token>';
$message = '<identifier>';
$identifier_hash = hash_hmac('sha256', $message, $key);
?>
Javascript (Node.js)
const crypto = require('crypto');
const key = '<webwidget-hmac-token>';
const message = '<identifier>';
const hash = crypto.createHmac('sha256', key).update(message).digest('hex');
Ruby
require 'openssl'
require 'base64'
key = '<webwidget-hmac-token>'
message = '<identifier>'
OpenSSL::HMAC.hexdigest('sha256', key, message)
Elixir
key = '<webwidget-hmac-token>'
message = '<identifier>'
signature = :crypto.hmac(:sha256, key, message)
Base.encode16(signature, case: :lower)
Golang
package main
import (
"crypto/hmac"
"crypto/sha256"
"encoding/base64"
"encoding/hex"
)
func main() {
secret := []byte("<webwidget-hmac-token>")
message := []byte("<identifier>")
hash := hmac.New(sha256.New, secret)
hash.Write(message)
hex.EncodeToString(hash.Sum(nil))
}
Python
import hashlib
import hmac
import base64
secret = bytes('<webwidget-hmac-token>', 'utf-8')
message = bytes('<identifier>', 'utf-8')
hash = hmac.new(secret, message, hashlib.sha256)
hash.hexdigest()
