Connect your WhatsApp account using Twilio, a powerful cloud communications platform. This guide will walk you through setting up a free test account and then moving to a live production environment.

Twilio Account Setup

To get started, you need a Twilio account.

Go to the Twilio Signup Page and create a new account. Once signed up, you will need to verify your phone number.

💪
Setup Tip: When asked, choose “WhatsApp”,
“Alerts & Notifications”, “With no code at all”, and “3rd party integrations” to customize your dashboard experience.

Testing with a Free Sandbox Account

Before you pay for anything, you can use Twilio’s free sandbox to test the integration with Chat.devad.io.

  1. Log in to your Twilio Console.
  2. Navigate to Messaging > Settings > WhatsApp sandbox settings in the left menu.
  3. You will see two fields: WHEN A MESSAGE COMES IN and STATUS CALLBACK URL.
  4. Go to your Chat.devad.io dashboard.
  5. Navigate to Settings > WhatsApp > Twilio settings and copy the Configuration URL.
  6. Paste this URL into both fields in Twilio.
  7. Save the changes.

Activate the Sandbox

  1. Go to Messaging > Try it out > Send a WhatsApp message in Twilio.
  2. Follow the on-screen instructions to send a code to the provided WhatsApp number from your personal WhatsApp.
  3. Once connected, send a test message!
✔️
Success! Chat.devad.io should now receive
messages sent to the sandbox account, and you can reply directly from the dashboard.
