The merchant SDK can be used for integrating with the Express Checkout, Mass Pay, Web Payments Pro APIs.
The Payment Card Industry (PCI) Council has mandated that early versions of TLS be retired from service. All organizations that handle credit card information are required to comply with this standard. As part of this obligation, PayPal is updating its services to require TLS 1.2 for all HTTPS connections. At this time, PayPal will also require HTTP/1.1 for all connections.

A new
modehas been created to test if your server/machine handles TLSv1.2 connections. Please usetlsmode instead ofsandboxto verify. You can return back tosandboxmode once you have verified. Please have a look at this Sample Configuration.
- Because of the Poodle vulnerability, PayPal has disabled SSLv3.
- To enable TLS encryption, the changes were made to PPHttpConfig.php in SDK Core to use a cipher list specific to TLS encryption.

PayPal's PHP Merchant SDK requires
- PHP 5.3 and above
- curl/openssl PHP extensions
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 composer (PHP V5.3+ only).
To use the SDK,
- Create a
composer.jsonfile with the following contents.
{
"name": "me/shopping-cart-app",
"require": {
"paypal/merchant-sdk-php":"3.8.*"
}
}- Install the SDK as a dependency using
composer. To downloadcomposer, follow installation instructions provided in Composer documentation. - Require
PPBootStrap.phpin your application. - 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.inifile 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
} 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);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, you can configure the SDK via the sdk_config.ini file.
define('PP_CONFIG_PATH', '/directory/that/contains/sdk_config.ini');
$service = new PayPalAPIInterfaceServiceService();You can refer full list of configuration parameters in wiki page.
Please refer to the IPN-README in 'samples/IPN' directory.
