sendmux/sdk

Umbrella package for Sendmux PHP SDK clients.

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

Requirements

• PHP 8.2 or newer.
• Composer.
• A Sendmux API key for each API surface you call.

Installation

composer require sendmux/sdk:^1.0

Usage

The umbrella package installs the core, sending, mailbox, and management packages together. Create clients through the surface package factories.

<?php

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

use Sendmux\Mailbox\ClientFactory as MailboxFactory;
use Sendmux\Management\ClientFactory as ManagementFactory;
use Sendmux\Sending\ClientFactory as SendingFactory;

$sending = SendingFactory::createEmailsApi(
    getenv('SENDMUX_MAILBOX_API_KEY') ?: ''
);

$mailbox = MailboxFactory::createMailboxAPIApi(
    getenv('SENDMUX_MAILBOX_API_KEY') ?: ''
);

$management = ManagementFactory::createMailboxesApi(
    getenv('SENDMUX_ROOT_API_KEY') ?: ''
);

Note

sendmux/sdk installs all PHP SDK surfaces. It does not replace the surface factories.
