README

A Laravel mail driver for the PX Mail (TX Mail) API.

Installation

composer require mindtwo/px-mail-laravel-driver

Configuration

Publish the config file

php artisan vendor:publish --tag=px-mail

This publishes config/px-mail.php. This step is optional if you configure everything via environment variables.

Environment variables

Add the following to your .env file:

TX_MAIL_URL=https://tx-mail.api.pl-x.cloud
TX_MAIL_TENANT=your-tenant
TX_MAIL_CLIENT_ID=your-client-id
TX_MAIL_CLIENT_SECRET=your-client-secret

Register the mailer

Add the transport to the mailers section in config/mail.php:

'mailers' => [
    'txmail' => [
        'transport' => 'txmail',
    ],
],

Then set it as your default mailer in .env:

MAIL_MAILER=txmail

Config reference

Key	Env variable	Default	Description
stage	APP_ENV	APP_ENV	The application stage. local is mapped to preprod automatically.
mailer_url	TX_MAIL_URL	—	Base URL of the TX Mail API.
mailer_api_version	TX_MAIL_API_VERSION	v1	API version appended to the base URL.
tenant	TX_MAIL_TENANT	—	Your TX Mail tenant identifier used in the API path.
client_id	TX_MAIL_CLIENT_ID	—	Client ID for M2M authentication.
client_secret	TX_MAIL_CLIENT_SECRET	—	Client secret for M2M authentication.
debug	TX_MAIL_DEBUG	false	When true, enables HTTP-level request/response logging for all API calls.
log_send	TX_MAIL_LOG_SEND	false	When true, logs each outgoing send attempt (sender, recipient, tenant, URL). Can be enabled independently of debug.
headers	—	[]	Additional headers merged into every request. See Additional headers.

Usage

Once configured, use Laravel's Mail facade as normal:

Mail::to($user)->send(new OrderConfirmation($order));

Context headers

The driver supports optional x-context-tenant-code and x-context-domain-code headers. These are useful in multi-tenant applications where the sending context needs to be forwarded to the mail API.

Set them on the ApiClient via the service container's resolving callback, typically inside a service provider:

use mindtwo\LaravelPxMail\Client\ApiClient;

$this->app->resolving(ApiClient::class, function (ApiClient $client) {
    $client->setContextTenant(tenant()->code);
    $client->setContextDomain(domain()->code);
});

The callbacks are resolved fresh on every ApiClient instantiation, so the values are always up to date.

You can also set them directly on the resolved instance at any point before sending:

app(ApiClient::class)
    ->setContextTenant('acme')
    ->setContextDomain('shop');

Additional headers

Static additional headers can be defined in the config:

// config/px-mail.php
'headers' => [
    'X-Custom-Header' => 'value',
],

They can also be set at runtime, for example in middleware:

config(['px-mail.headers' => ['X-Custom-Header' => 'value']]);

Logging

Send logging

Enable send logging to record every outgoing mail attempt:

TX_MAIL_LOG_SEND=true

Logs the tenant, client ID, API URL, sender address, and anonymized recipient (e.g. j***@example.com) before each send. All entries are prefixed with [px-mail].

Debug mode

Enable debug mode for HTTP-level logging:

TX_MAIL_DEBUG=true

Logs the full request and response details for every API call. Errors (4xx/5xx) are always logged regardless of this setting.

Both options can be combined or used independently.
