+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# REST API SDK for PHP V2
+
+![Home Image](homepage.jpg)
+
+### To consolidate support across various channels, we have currently turned off the feature of GitHub issues. Please visit https://www.paypal.com/support to submit your request or ask questions within our community forum.
+
+__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. 
+## Latest Updates
+Beginning January 2020, PayPal will require an update on the Personal Home Page (PHP) Checkout Software Developer Kit (SDK) to version 1.0.1. Merchants who have not updated their PHP Checkout SDK to version 1.0.1 will not be able to deserialize responses using outdated SDK integrations.
+All PHP Checkout SDK integrations are expected to be updated by March 1, 2020. Merchants are encouraged to prepare for the update as soon as possible to avoid possible service disruption.
+The Status Page has been updated with this information. The bulletin can be found [here](https://www.paypal-status.com/history/eventdetails/11015)
+
+## 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 contributing or referring 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());
+}
+```
+#### Example Output:
+```

+
+## 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:
+```php
+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());
+}
+```

+## PayPal HttpClient
+
+PayPalHttp is a generic HTTP Client.
+
+In it's simplest form, an [`HttpClient`](lib/PayPalHttp/HttpClient.php) exposes an `execute` method which takes an [HTTP request](lib/PayPalHttp/HttpRequest.php), executes it against the domain described in an [Environment](lib/PayPalHttp/Environment.php), and returns an [HTTP response](lib/PayPalHttp/HttpResponse.php).
+
+### Environment
+
+An [`Environment`](./lib/PayPalHttp/environment.rb) describes a domain that hosts a REST API, against which an `HttpClient` will make requests. `Environment` is a simple interface that wraps one method, `baseUrl`.
+
+```php
+$env = new Environment('https://example.com');
+```
+
+### Requests
+
+HTTP requests contain all the information needed to make an HTTP request against the REST API. Specifically, one request describes a path, a verb, any path/query/form parameters, headers, attached files for upload, and body data.
+
+### Responses
+
+HTTP responses contain information returned by a server in response to a request as described above. They are simple objects which contain a status code, headers, and any data returned by the server.
+
+```php
+$request = new HttpRequest("/path", "GET");
+$request->body[] = "some data";
+
+$response = $client->execute($req);
+
+$statusCode = $response->statusCode;
+$headers = $response->headers;
+$data = $response->result;
+```
+
+### Injectors
+
+Injectors are blocks that can be used for executing arbitrary pre-flight logic, such as modifying a request or logging data. Injectors are attached to an `HttpClient` using the `addInjector` method.
+
+The `HttpClient` executes its injectors in a first-in, first-out order, before each request.
+
+```php
+class LogInjector implements Injector
+{
+    public function inject($httpRequest)
+    {
+        // Do some logging here
+    }
+}
+
+$logInjector = new LogInjector();
+$client = new HttpClient($environment);
+$client->addInjector($logInjector);
+...
+```
+
+### Error Handling
+
+`HttpClient#execute` may throw an `Exception` if something went wrong during the course of execution. If the server returned a non-200 response, [IOException](lib/PayPalHttp/IOException.php) will be thrown, that will contain a status code and headers you can use for debugging.
+
+```php
+try
+{
+    $client->execute($req);
+}
+catch (HttpException $e)
+{
+    $statusCode = $e->response->statusCode;
+    $headers = $e->response->headers;
+    $body = $e->response->result;
+}
+```
