README

Sendmux Sending API client for PHP.

Read the PHP SDK guide at docs.sendmux.ai/sdks/php.

Requirements

• PHP 8.2 or newer.
• Composer.
• A mailbox-scoped API key with the smx_mbx_ prefix.

Installation

composer require sendmux/sending:^1.0

Usage

Create the API group client with a mailbox-scoped key.

<?php

require __DIR__ . '/vendor/autoload.php';

use Sendmux\Sending\ClientFactory;

$emails = ClientFactory::createEmailsApi(
    getenv('SENDMUX_MAILBOX_API_KEY') ?: ''
);

$meta = ClientFactory::createMetaApi(
    getenv('SENDMUX_MAILBOX_API_KEY') ?: ''
);

The generated EmailsApi exposes sendingSendEmail() and sendingSendEmailBatch(). The generated MetaApi exposes sendingGetOpenApiSpec().

Features

• Validates smx_mbx_ API keys before configuring the client.
• Uses https://smtp.sendmux.ai/api/v1 by default.
• Adds retry and rate-limit backoff behaviour through sendmux/core.
• Maps generated API responses into the shared Sendmux envelope and error model.
• Includes generated models for single-send and batch-send requests and responses.
