+# REST API SDK for PHP V2
+
+![Home Image](homepage.jpg)
+
+__Welcome to PayPal PHP SDK__. This repository contains PayPal's PHP SDK and samples for [v2/checkout/orders](https://developer.paypal.com/docs/api/orders/v2/) and [v2/payments](https://developer.paypal.com/docs/api/payments/v2/) APIs.
+
+This is a part of the next major PayPal SDK. It includes a simplified interface to only provide simple model objects and blueprints for HTTP calls. This repo currently contains functionality for PayPal Checkout APIs which includes [Orders V2](https://developer.paypal.com/docs/api/orders/v2/) and [Payments V2](https://developer.paypal.com/docs/api/payments/v2/).
+
+Please refer to the [PayPal Checkout Integration Guide](https://developer.paypal.com/docs/checkout/) for more information. Also refer to [Setup your SDK](https://developer.paypal.com/docs/checkout/reference/server-integration/setup-sdk/) for additional information about setting up the SDK's. 
+
+## Prerequisites
+
+PHP 5.6 and above
+
+An environment which supports TLS 1.2 (see the TLS-update site for more information)
+
+## Usage
+
+### Binaries
+
+It is not mandatory to fork this repository for using the PayPal SDK. You can refer [PayPal Checkout Server SDK](https://developer.paypal.com/docs/checkout/reference/server-integration) for configuring and working with SDK without forking this code.
+
+For contirbuting or referrring the samples, You can fork/refer this repository. 
+
+### 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 <b>Client ID</b> and <b>Secret</b> from there.
+
+```php
+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($environment);
+```
+
+## Examples
+### Creating an Order
+#### Code:
+```php
+// Construct a request object and set desired parameters
+// Here, OrdersCreateRequest() creates a POST request to /v2/checkout/orders
+use PayPalCheckoutSdk\Orders\OrdersCreateRequest;
+$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());
+}
+```

+// $response->result->id gives the orderId of the order created above
+$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
