Installation

You can install the package via composer:

Setting up your Facebook Bot

Follow the Getting Started guide in order to create a Facebook Messenger app, a Facebook page and a page token, which is connecting both.

Next we need to add this token to our Laravel configurations. Create a new Facebook section inside config/services.php and place the page token there:

Usage

Let's take an invoice-paid-notification as an example. You can now use the Facebook channel in your via() method, inside the InvoicePaid class. The to($userId) method defines the Facebook user, you want to send the notification to.

Based on the details you add (text, attachments etc.) will determine automatically the type of message to be sent. For example if you only add text() then it will be a basic message; using attach() will turn this into a attachment message. Having buttons or cards will change this to the Button Template and Generic Template respectivily

The notification will be sent from your Facebook page, whose page token you have configured earlier. Here's a screenshot preview of the notification inside the chat window.

Message Examples

Basic Text Message

Send a basic text message to a user

Attachment Message

Send a file attachment to a user (Example is sending a pdf invoice)

Generic (Card Carousel) Message

Send a set of cards / items to a user displayed in a carousel (Example is sending a set of links). Note you can also add up to three buttons per card

Routing a message

You can either send the notification by providing with the page-scoped user id (PSID) of the recipient to the to($userId) method like shown in the above example or add a routeNotificationForFacebook() method in your notifiable model:
