It is strongly recommended that new implementations use the [PHP Rest SDK](https://github.com/paypal/rest-api-sdk-php) [](#this-sdk-is-deprecated-it-is-strongly-recommended-that-new-implementations-use-the-php-rest-sdk) Prerequisites ------------- [](#prerequisites) PayPal's PHP Merchant SDK requires - PHP 5.2 and above - curl/openssl PHP extensions Running the sample ------------------ [](#running-the-sample) To run the bundled sample, first copy the samples folder to your web server root. You will then need to install the SDK as a dependency using either composer (PHP V5.3+ only) or by running a custom installation script provided with the SDK. If using composer, run `composer update` from the samples folder. Otherwise, run install.php from merchant-sdk-php/samples directory ``` cd samples curl https://raw.github.com/paypal/merchant-sdk-php/stable/samples/install.php | php OR php install.php ``` Using the SDK ------------- [](#using-the-sdk) To use the SDK, - Create a composer.json file with the following contents. ``` { "name": "me/shopping-cart-app", "require": { "paypal/merchant-sdk-php":"v2.*" } } ``` - Install the SDK as a dependency using composer or the install.php script. - Require `vendor/autoload.php` OR `PPBootStrap.php` in your application depending on whether you used composer or the custom installer. - Choose how you would like to configure the SDK - You can either - Create a hashmap containing configuration parameters and pass it to the service object OR - Create a `sdk_config.ini` file and set the PP\_CONFIG\_PATH constant to point to the directory where this file exists. - Instantiate a service wrapper object and a request object as per your project's needs. - Invoke the appropriate method on the service object. For example, ``` // Sets config file path(if config file is used) and registers the classloader require("PPBootStrap.php"); // Array containing credentials and confiuration parameters. (not required if config file is used) $config = array( 'mode' => 'sandbox', 'acct1.UserName' => 'jb-us-seller_api1.paypal.com', 'acct1.Password' => 'WX4WTU3S8MY44S7F' ..... ); // Create request details $itemAmount = new BasicAmountType($currencyId, $amount); $setECReqType = new SetExpressCheckoutRequestType(); $setECReqType->SetExpressCheckoutRequestDetails = $setECReqDetails; // Create request $setECReq = new SetExpressCheckoutReq(); $setECReq->SetExpressCheckoutRequest = $setECReqType; ...... // Perform request $paypalService = new PayPalAPIInterfaceServiceService($config); $setECResponse = $paypalService->SetExpressCheckout($setECReq); // Check results if(strtoupper($setECResponse->Ack) == 'SUCCESS') { // Success } ``` Authentication -------------- [](#authentication) The SDK provides multiple ways to authenticate your API call. ``` $paypalService = new PayPalAPIInterfaceServiceService($config); // Use the default account (the first account) configured in sdk_config.ini $response = $paypalService->SetExpressCheckout($setECReq); // Use a specific account configured in sdk_config.ini $response = $paypalService->SetExpressCheckout($setECReq, 'jb-us-seller_api1.paypal.com'); // Pass in a dynamically created API credential object $cred = new PPCertificateCredential("username", "password", "path-to-pem-file"); $cred->setThirdPartyAuthorization(new PPTokenAuthorization("accessToken", "tokenSecret")); $response = $paypalService->SetExpressCheckout($setECReq, $cred); ``` SDK Configuration ----------------- [](#sdk-configuration) The SDK allows you to configure the following parameters- - Integration mode (sandbox / live) - (Multiple) API account credentials. - HTTP connection parameters - Logging Dynamic configuration values can be set by passing a map of credential and config values (if config map is passed the config file is ignored) ``` $config = array( 'mode' => 'sandbox', 'acct1.UserName' => 'jb-us-seller_api1.paypal.com', 'acct1.Password' => 'WX4WTU3S8MY44S7F' ..... ); $service = new PayPalAPIInterfaceServiceService($config); ``` Alternatively, credential and configuration can be loaded from a file. ``` define('PP_CONFIG_PATH', '/directory/that/contains/sdk_config.ini'); $service = new PayPalAPIInterfaceServiceService(); ``` You can refer full list of configuration parameters in [wiki](https://github.com/paypal/sdk-core-php/wiki/Configuring-the-SDK) page. Please refer to the sample config file provided with this bundle for more.
