Setting up credentials

Get client ID and client secret by going to https://developer.paypal.com/developer/applications and generating a REST API app. Get Client ID and Secret from there.

require __DIR__ . '/vendor/autoload.php';
use PayPalCheckoutSdk\Core\PayPalHttpClient;
use PayPalCheckoutSdk\Core\SandboxEnvironment;
// Creating an environment
$clientId = "<<PAYPAL-CLIENT-ID>>";
$clientSecret = "<<PAYPAL-CLIENT-SECRET>>";

$environment = new SandboxEnvironment($clientId, $clientSecret);
$client = new PayPalHttpClient($environment);

Examples

Creating an Order

Code:

// Construct a request object and set desired parameters
// Here, OrdersCreateRequest() creates a POST request to /v2/checkout/orders
use PayPalCheckoutSdk\Orders\OrdersCreateRequest;
$request = new OrdersCreateRequest();
$request->prefer('return=representation');
$request->body = [
                     "intent" => "CAPTURE",
                     "purchase_units" => [[
                         "reference_id" => "test_ref_id1",
                         "amount" => [
                             "value" => "100.00",
                             "currency_code" => "USD"
                         ]
                     ]],
                     "application_context" => [
                          "cancel_url" => "https://example.com/cancel",
                          "return_url" => "https://example.com/return"
                     ] 
                 ];

try {
    // Call API with your client and get a response for your call
    $response = $client->execute($request);
    
    // If call returns body in response, you can get the deserialized version from the result attribute of the response
    print_r($response);
}catch (HttpException $ex) {
    echo $ex->statusCode;
    print_r($ex->getMessage());
}

Capturing an Order

Before capture, Order should be approved by the buyer using the approval URL returned in the create order response.

Code to Execute:

use PayPalCheckoutSdk\Orders\OrdersCaptureRequest;
// Here, OrdersCaptureRequest() creates a POST request to /v2/checkout/orders
// $response->result->id gives the orderId of the order created above
$request = new OrdersCaptureRequest("APPROVED-ORDER-ID");
$request->prefer('return=representation');
try {
    // Call API with your client and get a response for your call
    $response = $client->execute($request);
    
    // If call returns body in response, you can get the deserialized version from the result attribute of the response
    print_r($response);
}catch (HttpException $ex) {
    echo $ex->statusCode;
    print_r($ex->getMessage());
}
