PHP Quick Start

Install

1
{
2
  "require": {
3
    "sixmm/agent-sdk": "VERSION_PROVIDED_BY_6MM"
4
  }
5
}

Package access

6MM provides the approved Composer package name, source, and version during partner onboarding.

Before you start

• Confirm the Agent API base URL with 6MM.
• Load apiSecret from environment variables or secret management.
• Keep SDK usage inside backend services only.
• Prepare idempotent handling for transfer and webhook flows.

Initialize client

1
<?php
2
3
use Sixmm\Agent\AgentClient;
4
use Sixmm\Agent\AgentConfig;
5
6
$client = new AgentClient(new AgentConfig(
7
    'https://api.6mm.com/agent',
8
    'AGENT001',
9
    getenv('AGENT_API_SECRET') ?: '',
10
    'USDT'
11
));

Backend only

The PHP SDK signs Agent API requests and must not be exposed through public source code or frontend runtime environments.

Example: transfer funds in

1
$response = $client->transfer([
2
    'agentOrderNo' => 'AGT-ORDER-1001',
3
    'agentUserId' => 'agent-user-001',
4
    'direction' => 'IN',
5
    'currency' => 'USDT',
6
    'amount' => '10.00',
7
]);

Use decimal strings for amounts and preserve the original agentOrderNo when retrying or querying transfer status.
