Installation

1. Create an account at Paysuite.tech and obtain your access token from the dashboard

2. Install the library using Composer:

composer require hypertech/paysuite-php-sdk

Basic Usage

First, import and initialize the client with your token:

use Hypertech\Paysuite\Client;
use Hypertech\Paysuite\Exception\ValidationException;
use Hypertech\Paysuite\Exception\PaysuiteException;

$token = "your-access-token";
$client = new Client($token);

Create a Payment

try {
    $response = $client->createPayment([
        'amount' => '100.50',
        'reference' => 'INV123',
        'description' => 'Invoice payment',
        'return_url' => 'https://yoursite.com/return',
        'callback_url' => 'https://yoursite.com/callback'
    ]);

    if ($response->isSuccessfully()) {
        // Get the checkout URL to redirect the customer
        $checkoutUrl = $response->getCheckoutUrl();
        
        // Get the payment ID for later reference
        $paymentId = $response->getData()['id'];
        
        // Redirect customer to payment page
        header("Location: " . $checkoutUrl);
        exit;
    }
} catch (ValidationException $e) {
    // Handle validation errors
    echo "Validation error: " . $e->getMessage();
} catch (PaysuiteException $e) {
    // Handle API errors
    echo "API error: " . $e->getMessage();
}

Check Payment Status

try {
    $response = $client->getPayment($paymentId);
    
    if ($response->isSuccessfully()) {
        $status = $response->getData()['status'];
        
        // Check if transaction data is available
        if (isset($response->getData()['transaction'])) {
            $transaction = $response->getData()['transaction'];
            $transactionId = $transaction['transaction_id'];
            $paidAt = $transaction['paid_at'];
        }
    }
} catch (ValidationException $e) {
    echo "Validation error: " . $e->getMessage();
} catch (PaysuiteException $e) {
    echo "API error: " . $e->getMessage();
}

Validation Rules

The SDK implements comprehensive validation for all API requests:

1. Payment Request Validation:

   • amount: Must be a positive number
   • reference: Required string
   • description: Required string
   • return_url: Must be a valid URL

2. UUID Validation:

   • Payment IDs must follow the standard UUID format (8-4-4-4-12 hexadecimal characters)
   • Example: 550e8400-e29b-41d4-a716-446655440000

Response Handling

The Response class provides convenient methods to access payment data:

// Check if the request was successful
$isSuccess = $response->isSuccessfully();

// Get the full response content
$content = $response->getContent();

// Get just the data portion of the response
$data = $response->getData();

// Get specific fields with helper methods
$reference = $response->getReference();
$amount = $response->getAmount();
$checkoutUrl = $response->getCheckoutUrl();

// Get error message if request failed
$errorMessage = $response->getMessage();

Error Handling

The SDK includes two main types of exceptions:

• ValidationException: For input validation errors (missing fields, invalid values)
• PaysuiteException: For API errors (authentication, server errors, etc.)

Error responses include:

• HTTP 400: Bad Request (validation errors)
• HTTP 401: Unauthorized (invalid token)
• HTTP 404: Not Found (invalid payment ID)
• HTTP 500: Server Error
