With just a few lines of code, your application can send and receive messages with WhatsApp using the Twilio API for WhatsApp.
This WhatsApp Quickstart will teach you how to do this using the Twilio Sandbox for WhatsApp, PHP, and the Twilio PHP Twilio helper library. In this Quickstart, you will learn how to:
- Sign up for Twilio and activate the Sandbox.
- Opt-in to the Sandbox
- Send your first WhatsApp message
- Receive inbound WhatsApp messages
- Reply to incoming WhatsApp messages
Before you can send a WhatsApp message from your web language, you'll need to sign up for a Twilio account or sign into your existing account and activate the Twilio Sandbox for WhatsApp. It allows you to prototype with WhatsApp immediately using a shared phone number, without waiting for a dedicated number to be approved by WhatsApp.
To get started, select a number from the available sandbox numbers to activate your sandbox.
Be sure to take note of the phone number you choose in the Sandbox. You will need this later when we're ready to send some messages.
Before you can send any messages, you'll need to gather your Twilio account credentials. You can find these in the Twilio Console.
- アカウントSID - REST APIリクエストの認証に使用します
- Auth Token - Used to authenticate REST API requests
For all of our code snippets and curl examples, you will need to authenticate with the Account SID and Auth Token.
The next steps will involve writing some code. We've written up development environment setup in PHP, where you'll set up your dev environment and prepare to build a simple web app.
If you haven't yet set up your development environment to write some PHP, head there first to get ready. This quickstart will be waiting.
The sandbox is pre-provisioned with three Twilio phone numbers that are shared across all sandbox users. In order to use the Sandbox, you MUST start by opt-ing in to the sandbox by sending the phone number you chose a message from WhatsApp. Once opted-in, you will only receive messages from your specific Sandbox.
join <your sandbox keyword>” to your Sandbox number in WhatsApp to join your Sandbox, and we’ll reply with a confirmation that you’ve joined. Your sandbox keyword can be found in the console.
Once you join, you will only receive messages from your specific Sandbox. To disconnect from the sandbox, you can reply to the message from WhatsApp with `sandbox stop`, or switch to a different sandbox by messaging `
join <other sandbox keyword>`.
To invite someone else to your sandbox, create a link with the following format containing the opt-in message and send it to them:
whatsapp://send?phone=<Your Sandbox Number>&text=<your URL-encoded sandbox keyword>
You can also create a QR code with the link format above that users can scan on their phone to opt-in to your sandbox.
To send a message, use the following code and replace the to parameter in the constructor with the phone number for your personal WhatsApp account in the E.164 format. (If you haven't already, install WhatsApp on your device and register for an account.) For the from parameter, be sure to include the
whatsapp: channel identifier before the Sandbox number in E.164 format.
From parameter, you need your
Sender ID which should be shown on the installed channel in the Twilio Console, as shown previously.
When someone replies to one of your messages, you will receive a webhook request from Twilio.
You can configure webhooks by connecting your Sandbox to an app you've already built for handling incoming messages, or build a new one for WhatsApp messages.
This webhook request also supports TwiML (the Twilio Markup Language) just like a regular Twilio SMS request.
To handle this request, you need to set up a web application and expose it to the internet. The PHP SMS Quickstart shows you how to respond to a message and generate TwiML in PHP.
And - that's all there is to it; receiving and responding is exactly the same as you would do in any SMS app with our Messaging API. Cool, right?
Although these Quickstarts show you how to receive an SMS message, the webhook that Twilio will send will include the same parameters as an incoming SMS message, with the exception that To and From addresses will be set to the WhatsApp number receiving the message (
whatsapp:<E.164 formatted Twilio phone number associated with your business>) and the WhatsApp number sending the message (
whatsapp:<User’s E.164 phone number>), respectively.
Because the Twilio WhatsApp API is essentially the same as the Twilio Programmable SMS API, all of the documentation for that API applies to your apps sending and receiving messages with WhatsApp. To dive deeper with a WhatsApp integration, see the WhatsApp documentation overview as well as the API Reference.
Here are some areas you might like to explore next.
We can't wait to see what kind of WhatsApp integration you build!
