Quick Start - PHP ​

This guide will help you integrate the Code SDK into your PHP application, allowing you to create and verify payment intents seamlessly.

Prerequisites ​

  • PHP: Ensure you have PHP (version 7.4 or newer) installed.
  • Composer: PHP dependency manager. Install it from getcomposer.org.

Step 1: Install the Code PHP SDK ​

Use Composer to install the Code SDK. Navigate to your project directory and run:

bash
composer require code-wallet/client
composer require code-wallet/client

Step 2: Create a Payment Intent ​

Create a PHP script named createIntent.php and add the following code:

php
<?php
// createIntent.php

require 'vendor/autoload.php';

use CodeWallet\Client\PaymentIntents;

$paymentData = [
    'destination' => "E8otxw1CVX9bfyddKu3ZB3BVLa4VVF9J7CTPdnUwT9jR", // Replace with your destination address
    'amount' => 0.05, // Minimum amount is $0.05 USD
    'currency' => 'usd',
];

try {
    // Create a payment request intent
    $response = PaymentIntents::create($paymentData);
    echo "Payment Intent Created:\n";
    print_r($response);
} catch (Exception $e) {
    echo "Error creating payment intent: " . $e->getMessage();
}
<?php
// createIntent.php

require 'vendor/autoload.php';

use CodeWallet\Client\PaymentIntents;

$paymentData = [
    'destination' => "E8otxw1CVX9bfyddKu3ZB3BVLa4VVF9J7CTPdnUwT9jR", // Replace with your destination address
    'amount' => 0.05, // Minimum amount is $0.05 USD
    'currency' => 'usd',
];

try {
    // Create a payment request intent
    $response = PaymentIntents::create($paymentData);
    echo "Payment Intent Created:\n";
    print_r($response);
} catch (Exception $e) {
    echo "Error creating payment intent: " . $e->getMessage();
}

Run the script:

bash
php createIntent.php
php createIntent.php

You should see a response indicating that the payment intent has been created, including an id and clientSecret.

Step 3: Verify the Payment Intent ​

Create another PHP script named verifyIntent.php to verify the status of the payment intent:

php
<?php
// verifyIntent.php

require 'vendor/autoload.php';

use CodeWallet\Client\PaymentIntents;

// Replace 'your-intent-id' with the actual intent ID returned from createIntent.php
$intentId = 'your-intent-id';

try {
    // Verify the intent status
    $status = PaymentIntents::getStatus($intentId);
    echo "Payment Intent Status:\n";
    print_r($status);
} catch (Exception $e) {
    echo "Error verifying payment intent: " . $e->getMessage();
}
<?php
// verifyIntent.php

require 'vendor/autoload.php';

use CodeWallet\Client\PaymentIntents;

// Replace 'your-intent-id' with the actual intent ID returned from createIntent.php
$intentId = 'your-intent-id';

try {
    // Verify the intent status
    $status = PaymentIntents::getStatus($intentId);
    echo "Payment Intent Status:\n";
    print_r($status);
} catch (Exception $e) {
    echo "Error verifying payment intent: " . $e->getMessage();
}

Run the verification script:

bash
php verifyIntent.php
php verifyIntent.php

This will output the current status of the specified payment intent.

Notes ​

  • Destination Address: Ensure that the destination address is a valid Solana address associated with your Code Wallet.
  • Amount Constraints: The minimum payment amount is $0.05 USD, the maximum is $250 USD. Adjust the amount as needed.

Further Steps ​

  • Integrate with Your Application: Incorporate the SDK into your application's backend to handle payments dynamically.
  • Explore Advanced Features: Look into features like Payment Fees, Tipping, and Idempotency to enhance your payment flows.
  • Check Examples: Refer to the PHP Examples repository for more comprehensive use cases.
