How to send Chat Messages

New in version 5.0: The Notifier component was introduced in Symfony 5.0.

The Symfony\Component\Notifier\ChatterInterface class allows you to send messages to chat services like Slack or Telegram:

// src/Controller/CheckoutController.php
namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Notifier\ChatterInterface;
use Symfony\Component\Notifier\Message\ChatMessage;
use Symfony\Component\Routing\Annotation\Route;

class CheckoutController extends AbstractController
{
    /**
     * @Route("/checkout/thankyou")
     */
    public function thankyou(ChatterInterface $chatter)
    {
        $message = (new ChatMessage('You got a new invoice for 15 EUR.'))
            // if not set explicitly, the message is send to the
            // default transport (the first one configured)
            ->transport('slack');

        $sentMessage = $chatter->send($message);

        // ...
    }
}

The send() method returns a variable of type Symfony\Component\Notifier\Message\SentMessage which provides information such as the message ID and the original message contents.

New in version 5.2: The SentMessage class was introduced in Symfony 5.2.

Adding Interactions to a Slack Message

With a Slack message, you can use the Symfony\Component\Notifier\Bridge\Slack\SlackOptions class to add some interactive options called Block elements:

use Symfony\Component\Notifier\Bridge\Slack\Block\SlackActionsBlock;
use Symfony\Component\Notifier\Bridge\Slack\Block\SlackDividerBlock;
use Symfony\Component\Notifier\Bridge\Slack\Block\SlackImageBlockElement;
use Symfony\Component\Notifier\Bridge\Slack\Block\SlackSectionBlock;
use Symfony\Component\Notifier\Bridge\Slack\SlackOptions;
use Symfony\Component\Notifier\Message\ChatMessage;

$chatMessage = new ChatMessage('Contribute To Symfony');

// Create Slack Actions Block and add some buttons
$contributeToSymfonyBlocks = (new SlackActionsBlock())
    ->button(
        'Improve Documentation',
        'https://symfony.com/doc/current/contributing/documentation/standards.html',
        'primary'
    )
    ->button(
        'Report bugs',
        'https://symfony.com/doc/current/contributing/code/bugs.html',
        'danger'
    );

$slackOptions = (new SlackOptions())
    ->block((new SlackSectionBlock())
        ->text('The Symfony Community')
        ->accessory(
            new SlackImageBlockElement(
                'https://symfony.com/favicons/apple-touch-icon.png',
                'Symfony'
            )
        )
    )
    ->block(new SlackDividerBlock())
    ->block($contributeToSymfonyBlocks);

// Add the custom options to the chat message and send the message
$chatMessage->options($slackOptions);

$chatter->send($chatMessage);

Adding Fields and Values to a Slack Message

use Symfony\Component\Notifier\Bridge\Slack\Block\SlackDividerBlock;
use Symfony\Component\Notifier\Bridge\Slack\Block\SlackSectionBlock;
use Symfony\Component\Notifier\Bridge\Slack\SlackOptions;
use Symfony\Component\Notifier\Message\ChatMessage;

$chatMessage = new ChatMessage('Symfony Feature');

$options = (new SlackOptions())
    ->block((new SlackSectionBlock())->text('My message'))
    ->block(new SlackDividerBlock())
    ->block(
        (new SlackSectionBlock())
            ->field('*Max Rating*')
            ->field('5.0')
            ->field('*Min Rating*')
            ->field('1.0')
    );

// Add the custom options to the chat message and send the message

use Symfony\Component\Notifier\Bridge\Slack\Block\SlackSectionBlock;
use Symfony\Component\Notifier\Bridge\Slack\SlackOptions;

$options = (new SlackOptions())
    ->block((new SlackHeaderBlock('My Header')))
    ->block((new SlackSectionBlock())->text('My message'))
    ->block(new SlackDividerBlock())
    ->block(
        (new SlackSectionBlock())
            ->field('*Max Rating*')
            ->field('5.0')
            ->field('*Min Rating*')
