Twilio webhook setup with Webhookify

Twilio is the leading cloud communications platform that enables developers to programmatically send and receive SMS messages, make and receive phone calls, and handle a wide range of communication workflows. Whether you are building a customer support system, sending OTP codes, or managing a call center, Twilio webhooks are the backbone of event-driven communication. However, monitoring those webhook events in real time can be challenging, especially when you need instant alerts across multiple channels. That is where Webhookify comes in -- it lets you create a webhook endpoint in seconds and receive AI-powered, human-readable notifications on Telegram, Discord, Slack, Email, or mobile push notifications whenever Twilio fires an event.

In this guide, you will learn exactly how to connect Twilio webhooks to Webhookify so that every incoming SMS, call status update, or recording event triggers an instant notification on your preferred channel. No server setup, no custom code, and no complex infrastructure required.

Why Monitor Twilio Webhooks with Webhookify?

  • Instant Delivery Confirmations: Know the moment an SMS is delivered, bounced, or marked as undelivered. Webhookify sends you a push notification or Telegram message within seconds so you never miss a failed delivery.

  • Real-Time Call Monitoring: Track call status changes -- ringing, in-progress, completed, busy, failed, or no-answer -- without constantly refreshing the Twilio console. Get alerts the instant a call completes or fails so your team can respond immediately.

  • AI-Powered Summaries: Instead of parsing raw JSON payloads, Webhookify uses AI to summarize each Twilio event into a clear, human-readable message. You will see "SMS delivered to +1-555-0123" rather than a wall of JSON data.

  • Multi-Channel Alerts: Route Twilio notifications to Telegram for personal alerts, Discord or Slack for team channels, Email for compliance records, or mobile push for on-the-go monitoring. Use any combination that fits your workflow.

  • Zero Infrastructure: No need to spin up a server, write webhook handler code, or manage uptime. Webhookify gives you a ready-to-use HTTPS endpoint that captures every Twilio event and forwards it as a notification.

Prerequisites

  1. A Twilio account (free trial or paid). Sign up at twilio.com if you do not have one.
  2. At least one Twilio phone number provisioned in your account.
  3. A Webhookify account. Sign up for free at webhookify.app.
  4. A notification channel configured in Webhookify (Telegram bot, Discord webhook, Slack workspace, or Email address).
  5. Basic familiarity with the Twilio Console dashboard.

Step-by-Step Setup Guide

1

Create a Webhookify Endpoint

Start by logging in to your Webhookify dashboard at webhookify.app. If you do not have an account yet, sign up for free -- no credit card required.

Once logged in, click the "Create Endpoint" button. Give your endpoint a descriptive name such as "Twilio SMS Notifications" or "Twilio Call Alerts" so you can easily identify it later. Webhookify will generate a unique HTTPS URL that looks like:

https://hook.webhookify.app/w/your-unique-endpoint-id

Copy this URL to your clipboard. You will paste it into the Twilio Console in a later step. This endpoint is immediately active and ready to receive webhook payloads from Twilio.

Configure Your Notification Channel

Before connecting Twilio, set up where you want to receive alerts. In your Webhookify dashboard, navigate to Settings and choose your preferred notification channel:

  • Telegram: Click "Connect Telegram" and follow the bot setup flow. You will authorize the Webhookify bot to send messages to your chat or group.
  • Discord: Paste a Discord webhook URL from your server's channel settings (Channel Settings > Integrations > Webhooks).
  • Slack: Install the Webhookify Slack app or paste an incoming webhook URL from your Slack workspace.
  • Email: Enter the email address where you want to receive webhook alerts.
  • Mobile Push: Download the Webhookify app on iOS or Android and enable push notifications.

You can configure multiple channels simultaneously. For example, send critical call failures to Slack for your team and SMS delivery receipts to your personal Telegram.

Set Up Webhooks in Twilio

Now navigate to the Twilio Console at console.twilio.com. There are several places where you can configure webhooks depending on the type of events you want to monitor:

For SMS / Messaging Webhooks:

  1. Go to Phone Numbers > Manage > Active Numbers.
  2. Click on the phone number you want to monitor.
  3. Under the Messaging section, find the field labeled "A message comes in".
  4. Set the dropdown to Webhook and paste your Webhookify endpoint URL.
  5. Set the HTTP method to POST.
  6. Optionally, configure the "Status Callback URL" field with the same Webhookify URL to receive delivery status updates (sent, delivered, undelivered, failed).

For Voice / Call Webhooks:

  1. On the same phone number configuration page, scroll to the Voice section.
  2. In the "A call comes in" field, you can set a status callback URL.
  3. Under "Status Callback URL", paste your Webhookify endpoint URL to receive call status events.
  4. Check the status callback events you want: initiated, ringing, answered, completed.

Click Save to apply the configuration.

Select Events to Monitor

Twilio sends different types of webhook events depending on your configuration. Here are the key events you can monitor and what they mean:

  • Incoming SMS: Triggered when someone sends an SMS to your Twilio number. The payload includes the sender's number, message body, and media URLs if any.
  • Message Status Callbacks: Triggered when the delivery status of an outbound SMS changes. Statuses include queued, sent, delivered, undelivered, and failed.
  • Call Status Callbacks: Triggered at each stage of a phone call. Statuses include initiated, ringing, in-progress, completed, busy, failed, and no-answer.
  • Recording Completed: Triggered when a call recording finishes processing. Includes the recording URL and duration.
  • Transcription Completed: Triggered when a voice transcription is ready. Includes the transcribed text.

Configure each relevant callback URL in the Twilio Console to point to your Webhookify endpoint. You can use the same endpoint URL for all event types -- Webhookify will differentiate them automatically based on the payload content.

Test Your Configuration

With everything connected, it is time to verify the setup works correctly:

  1. Test SMS: Send a text message to your Twilio phone number from any phone. Within seconds, you should receive a notification on your configured channel showing the sender's number and message content.
  2. Test Outbound SMS: Use the Twilio Console or API to send an SMS. You should receive status callback notifications as the message progresses through queued, sent, and delivered states.
  3. Test Voice: Call your Twilio phone number. You should see call status notifications for ringing, in-progress, and completed.

Check your Webhookify dashboard to see the full webhook payload logged in real time. Each event is displayed with its raw JSON data and an AI-generated summary for quick reading.

If you do not receive notifications, double-check that the Webhookify URL is correctly pasted in the Twilio Console and that your notification channel is properly connected.

Twilio Webhook Events You Can Monitor

Twilio offers a comprehensive set of webhook events across its products. Here are the most common events you can route through Webhookify:

Messaging Events:

  • incoming_message -- An SMS or MMS is received on your Twilio number
  • message.queued -- Outbound message is queued for sending
  • message.sent -- Message has been sent to the carrier
  • message.delivered -- Message was successfully delivered to the recipient
  • message.undelivered -- Message could not be delivered
  • message.failed -- Message failed to send entirely

Voice Events:

  • call.initiated -- An outbound call has been initiated
  • call.ringing -- The call is ringing on the recipient's phone
  • call.in-progress -- The call has been answered and is active
  • call.completed -- The call has ended normally
  • call.busy -- The recipient's line was busy
  • call.failed -- The call could not be connected
  • call.no-answer -- The call was not answered

Recording Events:

  • recording.completed -- A call recording has finished processing
  • recording.failed -- A recording could not be completed

Transcription Events:

  • transcription.completed -- A voice transcription is ready
  • transcription.failed -- Transcription processing failed

Real-World Use Cases

  • Customer Support Monitoring: Route incoming SMS messages to a Slack channel so your support team gets instant alerts when customers text your business number. The AI summary shows the customer's message at a glance, enabling faster response times.

  • OTP Delivery Tracking: If your application sends one-time passwords via Twilio, monitor delivery status webhooks to detect failed deliveries in real time. Get an immediate Discord or Telegram alert when an OTP fails to deliver so you can trigger a retry or alternative verification method.

  • Call Center Oversight: Track call status events to monitor your call center's performance. Receive push notifications when calls fail or go unanswered, and use the Webhookify dashboard to review call patterns over time.

  • Recording and Compliance: Get notified instantly when call recordings are completed and ready for review. This is critical for industries with compliance requirements where recordings must be reviewed within specific timeframes.

Example Notification

When Twilio sends a webhook for an incoming SMS, Webhookify delivers a notification like this:

{
  "event": "Incoming SMS",
  "from": "+1-555-0199",
  "to": "+1-555-0100",
  "body": "Hi, I'd like to schedule an appointment for next Tuesday.",
  "numMedia": "0",
  "messageSid": "SM1a2b3c4d5e6f7g8h9i0j",
  "accountSid": "AC...",
  "timestamp": "2026-02-21T14:32:00Z"
}

Webhookify's AI-powered summary would display this as:

Incoming SMS from +1-555-0199: "Hi, I'd like to schedule an appointment for next Tuesday." -- Received at 2:32 PM UTC

This human-readable format makes it easy to scan notifications and take action without opening the Twilio Console.

Troubleshooting

  1. No notifications received after sending a test SMS: Verify that you pasted the Webhookify URL in the correct field in the Twilio Console. For incoming messages, the URL goes in the "A message comes in" field. For delivery receipts, it goes in the "Status Callback URL" field. Also confirm the HTTP method is set to POST.

  2. Receiving duplicate notifications: If you configured the same Webhookify URL in both the "A message comes in" and "Status Callback URL" fields, you will receive multiple events for a single SMS (the incoming event plus delivery status updates). This is expected behavior. If you only want incoming message alerts, remove the URL from the Status Callback field.

  3. Twilio shows a "Bad Gateway" or "Connection Error": This usually means the webhook URL is incorrect or has a typo. Copy the URL directly from your Webhookify dashboard and paste it again. Webhookify endpoints are always available and do not go down.

  4. Notifications are delayed by more than a few seconds: Check your notification channel connection in Webhookify settings. If using Telegram, ensure the bot has not been blocked. If using Slack, verify the webhook URL is still active in your Slack workspace settings.

  5. Webhook payloads appear empty or incomplete: Twilio sends payloads as application/x-www-form-urlencoded by default. Webhookify handles this format automatically, but if you see issues, check that no middleware or proxy is stripping the request body before it reaches the endpoint.

You can use the same Webhookify endpoint for multiple Twilio phone numbers. Simply paste the same URL into the webhook settings of each number. Webhookify will log and differentiate events based on the "To" and "From" fields in each payload, making it easy to manage all your Twilio numbers from one dashboard.
