Facebook Messenger (Public Beta)

All of the following steps are done through the Twilio Console. In the Facebook Messenger ecosystem, users communicate with brands and companies by messaging their Facebook Page. Twilio creates a Sender for each Facebook Page that you wish to use for messaging. A Sender is the identity used in the "From" field to send messages to your users.

To get started, first go to the Channels area in the Twilio Console, click on Facebook Messenger and install it.

Next, navigate to the Facebook Messenger channel that was just installed and click the "Connect with Facebook" button. Follow the prompts to select the Facebook Pages you want to authorize to configure as senders. In this step, you will be authorizing Twilio's Facebook Application to send and receive messages on behalf of your Facebook Page(s), thereby enabling access to Facebook Messenger through the Twilio Programmable Messaging API.

Note: You do not have to set up your own Facebook Application, as Twilio takes care of that for you.

Next, let's configure the Facebook Page you wish to use as a sender. While on the Twilio Channels Catalog page:

• Under the "Properties" heading in the Unique Name input field, enter a name of your choice for your page (Optional).
• Under the "Credentials" heading click the Select a Page dropdown and select a single Facebook Page to use as a sender.
• Under the "Configuration" heading in the Callback URL input field, enter a webhook URL where you can receive incoming messages sent to the Facebook Page from your end users.

Finally, click the "Save" button. This creates an instance of the Facebook Page that you can now use as a Sender.

Once a Channel is authenticated, you can now configure it to work with a Twilio API :

Twilio supports creating multiple instances so that your application can support different Facebook Pages. If you wish to configure more than one Facebook Page as a sender, you can click "Add Another Instance" and repeat the steps above for each new Facebook Page.

For Independent Software Vendors (ISV's) and Software Integrators (SI's) who are managing Facebook Messenger communications on behalf of your clients, you need to have admin access to each Facebook page.

You can use up to 25 Facebook pages per Twilio account or subaccount. To use additional Facebook pages, use additional subaccounts.

Now that your Facebook Messenger Sender is set up, you need to receive a message from an end user in order to respond. Facebook users need to initiate contact with you by messaging your Facebook Page before you are able to contact them. Once a user's message is received, you can respond back to the user for 24 hours. For more details, see Platform Policy Overview (Facebook for Developers).

When a user sends a message to your Facebook Page, your callback URL will receive the message with the same parameters as a standard Twilio WhatsApp or SMS message. Facebook Messenger sender and recipients have the format messenger:{messenger id}. You will need to retrieve the Facebook Messenger user ID from the callback response.

To send a Facebook message, make an HTTP POST request to Twilio's Programmable Messaging Message REST API resource with three required pieces of information:

• A recipient.
• A sender.
• Your message body.

See the REST API: Sending a SMS or MMS or REST API: Messages page for details.

You are also responsible for managing consumer opt-ins and opt-outs to Facebook Messenger platforms. Users grant you permission to message them by way of initiating the conversation with your Facebook Page. When users request that you stop messaging, you are required to stop messaging them. Users also have the option to block your page from reaching out to them again.

A business must strictly adhere to Facebook's commerce and business policies and is also expected to provide high quality experiences in Messenger. During or after the interaction in Messenger, users can provide negative feedback to Facebook when a page's conversations are considered spammy, abusive, or unpleasant. It is recommended that you maintain high quality, value-adding conversations that are aligned with the user's intention in engaging with you. If a business shows a pattern of violating Facebook's policies, Facebook will disable the page from using Facebook Messenger.
