Installation

composer require somehow-digital/symfony-lettermint-mailer

Configuration

# API
MAILER_DSN=lettermint+api://TOKEN@default?route=my-route

# SMTP
MAILER_DSN=lettermint+smtp://TOKEN@default

Route per Email

Set a route for each email using the RouteHeader:

use SomehowDigital\Symfony\Component\Mailer\Bridge\Lettermint\Header\RouteHeader;
$email->getHeaders()->add(new RouteHeader('my-route'));

Webhook

Configure the webhook routing:

framework:
    webhook:
        routing:
            lettermint_mailer:
                service: mailer.webhook.request_parser.lettermint
                secret: '%env(LETTERMINT_WEBHOOK_SECRET)%'

And a consumer:

#[AsRemoteEventConsumer(name: 'lettermint_mailer')]
class LettermintMailEventConsumer implements ConsumerInterface
{
    public function consume(RemoteEvent|AbstractMailerEvent $event): void
    {
        // your code
    }
}
