Notifications en temps rรฉel pour les messages SMS, WhatsApp et Email entrants.

Vue d'ensemble

RCSZilla peut envoyer des requรชtes HTTP POST ร  votre serveur lorsque des รฉvรฉnements spรฉcifiques se produisent. Cela vous permet de crรฉer des intรฉgrations en temps rรฉel sans polling.

Vรฉrification des signatures

If you configure a webhook secret, each delivery includes an X-RCSZilla-Signature header. Verify it like this:

PHP
<?php
$payload = file_get_contents('php://input');
$secret  = 'whsec_your_secret_here';

$header    = $_SERVER['HTTP_X_RCSZILLA_SIGNATURE'] ?? '';
$expected  = 'sha256=' . hash_hmac('sha256', $payload, $secret);

if (!hash_equals($expected, $header)) {
    http_response_code(401);
    exit('Invalid signature');
}

$data = json_decode($payload, true);
// Process the event...
http_response_code(200);
echo json_encode(['ok' => true]);
Node.js
const crypto = require('crypto');

app.post('/webhook', (req, res) => {
  const payload = JSON.stringify(req.body);
  const secret  = 'whsec_your_secret_here';
  const sig     = req.headers['x-rcszilla-signature'] || '';
  const expected = 'sha256=' + crypto.createHmac('sha256', secret)
                                      .update(payload).digest('hex');

  if (sig !== expected) return res.status(401).send('Invalid signature');

  const { event, data } = req.body;
  console.log(`Received ${event}:`, data);
  res.json({ ok: true });
});
Python
import hmac, hashlib, json
from flask import Flask, request, abort

app = Flask(__name__)
SECRET = 'whsec_your_secret_here'

@app.route('/webhook', methods=['POST'])
def webhook():
    payload = request.get_data()
    sig     = request.headers.get('X-RCSZilla-Signature', '')
    expected = 'sha256=' + hmac.new(
        SECRET.encode(), payload, hashlib.sha256
    ).hexdigest()

    if not hmac.compare_digest(sig, expected):
        abort(401)

    data = json.loads(payload)
    print(f"Event: {data['event']}", data['data'])
    return {'ok': True}

Politique de rรฉessai

If your endpoint returns a non-2xx status code, times out (10 seconds), or is unreachable, the delivery is retried with exponential backoff:

AttemptDelay
1st retry1 minute
2nd retry5 minutes
3rd retry30 minutes
4th retry2 hours
5th retry (final)12 hours
*
After 5 failed attempts the webhook is marked as permanently failed. Successfully delivered webhooks are automatically cleaned up after 7 days. Failed deliveries are retained for 30 days.

n8n Integration

To receive webhooks in n8n:

  1. Add a Webhook node to your workflow and copy its URL.
  2. Paste that URL into the webhook URL field in {APP_NAME} (Devices → Webhooks or Email Servers → IMAP).
  3. Test to confirm n8n receives the event.
  4. Connect downstream nodes to process the data (e.g., send a Slack message, update a CRM, trigger a reply).

Configuration Cron

Add these cron jobs to your server:

crontab
# Fire pending webhooks (every minute)
* * * * * /usr/bin/php /path/to/send_sms/cron/process_webhook_queue.php

# Poll IMAP inboxes for new emails (every 2 minutes)
*/2 * * * * /usr/bin/php /path/to/send_sms/cron/process_incoming_emails.php
