PayPal PHP ButtonManager SDK

Prerequisites

PayPal's PHP ButtonManager SDK requires

• PHP 5.2 and above
• curl/openssl PHP extensions

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 buttonmanager-sdk-php/samples directory

   
    cd samples
    curl  https://raw.github.com/paypal/buttonmanager-sdk-php/stable/samples/install.php | php
		OR
    php install.php

Using the SDK

To use the SDK,

• Create a composer.json file with the following contents.

{
    "name": "me/shopping-cart-app",
    "require": {
        "paypal/buttonmanager-sdk-php":"v2.5.106"
    }
}

• 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'
       .....
    );

	$buttonSearchReq = new BMButtonSearchReq();
	$buttonSearchReq->BMButtonSearchRequest = new BMButtonSearchRequestType();
	......

	$paypalService = new PayPalAPIInterfaceServiceService($config);
	$buttonSearchResponse = $paypalService->BMButtonSearch($buttonSearchReq);
	
	if($strtoupper($buttonSearchResponse->Ack) == 'SUCCESS') {
		// Success
	}

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 = $paypalService->BMButtonSearch($buttonSearchReq);	

	// Use a specific account configured in sdk_config.ini
	$response = $paypalService->BMButtonSearch($buttonSearchReq, '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 = $paypalService->BMButtonSearch($buttonSearchReq, $cred);	

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. refer https://github.com/paypal/buttonmanager-sdk-php/wiki for example

    define('PP_CONFIG_PATH', '/directory/that/contains/sdk_config.ini');
    $service  = new PayPalAPIInterfaceServiceService();

You can refer full list of configuration parameters in wiki page.
