Overview

The MT5 Manager API uses bearer token authentication. You must first initialize a connection to obtain a token, then use that token for all subsequent API calls.

​
Authentication Flow

The authentication process follows these steps:
  1. Call the /init/ endpoint with your MT5 server credentials
  2. Receive a bearer token in the response
  3. Configure the SDK with the token
  4. Make authenticated API calls

​
Step 1: Initialize Connection

Use the initGet() method to authenticate and obtain a token: 
use D4T\MT5Sdk\MT5Manager\BasicApi;
use D4T\MT5Sdk\Configuration;

// Create configuration and API instance
$config = new Configuration();
$config->setHost('https://your-mt5-server.com/v1');

$api = new BasicApi(null, $config);

// Initialize connection and get token
try {
    $result = $api->initGet(
        $server = '127.0.0.1:443',    // MT5 server IP with port
        $login = 'manager_login',      // Manager login
        $password = 'manager_password', // Manager password
        $timeout = 5000                 // Optional timeout in milliseconds
    );
    
    $token = $result->getToken();
    echo "Authentication successful! Token: " . $token;
} catch (\D4T\MT5Sdk\ApiException $e) {
    echo "Authentication failed: " . $e->getMessage();
}

Step 2: Configure SDK with Token

Once you receive the token, configure it for subsequent API calls: 
// Set the access token for bearer authentication
$config->setAccessToken($token);

// Now you can make authenticated API calls
$api = new BasicApi(null, $config);
The token is automatically included in the Authorization header as Bearer {token} for all authenticated endpoints.

​
Bearer Token Usage

After configuration, the SDK automatically adds the bearer token to all API requests. Here’s how it works internally (from BasicApi.php:616-619): 
// This endpoint requires Bearer token
if ($this->config->getAccessToken() !== null) {
    $headers['Authorization'] = 'Bearer ' . $this->config->getAccessToken();
}

Complete Example

Here’s a full workflow from authentication to making an API call: 
use D4T\MT5Sdk\MT5Manager\BasicApi;
use D4T\MT5Sdk\Configuration;
use D4T\MT5Sdk\ApiException;

// Step 1: Create configuration
$config = new Configuration();
$config->setHost('https://your-mt5-server.com/v1');

// Step 2: Initialize and authenticate
$api = new BasicApi(null, $config);

try {
    // Get authentication token
    $initResult = $api->initGet('127.0.0.1:443', 'manager_login', 'manager_password');
    $token = $initResult->getToken();
    
    // Step 3: Configure SDK with token
    $config->setAccessToken($token);
    
    // Step 4: Make authenticated requests
    $pingResult = $api->pingGet();
    echo "Ping successful: " . $pingResult->getMessage();
    
} catch (ApiException $e) {
    echo "Error: " . $e->getMessage() . "\n";
    echo "HTTP Code: " . $e->getCode() . "\n";
}
Store your bearer token securely. Never commit tokens to version control or expose them in client-side code.

​
Token Management

The Configuration class provides methods for managing access tokens: 
// Set access token
$config->setAccessToken($token);

// Get current access token
$currentToken = $config->getAccessToken();

// Check if token is set
if ($config->getAccessToken() !== null) {
    // Token is configured
}

​
Security Best Practices

  • Store tokens in environment variables or secure configuration files
  • Use HTTPS for all API communications
  • Implement token refresh logic if your tokens expire
  • Never log or display tokens in production environments
