The repository contains the PayPal Core SDK C#.NET Class Library Application and the UnitTest C#.NET Class Library NUnit Test Application.

• Visual Studio 2005 or higher
• NUnit 2.6.2 for PayPalCoreSDK Unit Test
• log4net 1.2.10 for PayPalCoreSDK Error Log
• NuGet 2.2 for NuGet Installation of log4net
• Note: NuGet 2.2 requires .NET Framework 4.0

• The PayPal Core SDK is used to call the PayPal Platform API Web Service for the given payload and PayPal API profile settings.

• The PayPal Core SDK addresses the essential needs of the PayPal API caller: Frequent and up-to-date releases: The PayPal Core SDK is available on NuGet, which translates as immediate SDK refreshes upon updates to PayPal APIs. Simpler configuration: A single configuration file that lets you manage your API credentials (supports multiple credentials), connectivity details, and service endpoints. Error log: The PayPal Core SDK uses the log4net tool to log output statements to a text file to help locate the problem. Backward compatibility: The PayPal Core SDK is developed using .NET Framework 2.0 and should compile on later versions of the .NET Framework.

• Redirect your buyer to obtain authorization.
• Capture the authorization code that is available as a query parameter ("code") in the redirect url
• Exchange the authorization code for a access token, refresh token, id token combo

Dictionary<string, string> configurationMap1 = new Dictionary<string, string>();
configurationMap1.Add("clientId", "...");
configurationMap1.Add("clientSecret", "...");
configurationMap1.Add("service.EndPoint", "https://api.paypal.com/");
APIContext apiContext1 = new APIContext();
apiContext1.Config = configurationMap1;

...

CreateFromAuthorizationCodeParameters param13 = new CreateFromAuthorizationCodeParameters();
param13.setCode("code");
Tokeninfo info13 = Tokeninfo.CreateFromAuthorizationCode(apiContext, param13);
string accessToken3 = info13.access_token;

• The access token is valid for a predefined duration and can be used for seamless XO or for retrieving user information

Dictionary<string, string> configurationMap2 = new Dictionary<string, string>();
configurationMap2.Add("clientId", "...");
configurationMap2.Add("clientSecret", "...");
configurationMap2.Add("service.EndPoint", "https://api.paypal.com/");
APIContext apiContext2 = new APIContext();
apiContext2.Config = configurationMap2;

...

Tokeninfo info2 = new Tokeninfo();
info2.refresh_token = "refreshToken";
UserinfoParameters param2 = new UserinfoParameters();
param2.setAccessToken(info2.access_token);
Userinfo userInfo = Userinfo.GetUserinfo(apiContext2, param2);

• If the access token has expired, you can obtain a new access token using the refresh token from the 3'rd step.

Dictionary<string, string> configurationMap3 = new Dictionary<string, string>();
configurationMap3.Add("clientId", "...");
configurationMap3.Add("clientSecret", "...");
configurationMap3.Add("service.EndPoint", "https://api.paypal.com/");
APIContext apiContext3 = new APIContext();
apiContext3.Config = configurationMap3;

...

CreateFromRefreshTokenParameters param3 = new CreateFromRefreshTokenParameters();
param3.setScope("openid"); // Optional
Tokeninfo info3 = new Tokeninfo(); // Create Token info object; setting the refresh token
info3.refresh_token = "refreshToken";

info3.CreateFromRefreshToken(apiContext3, param3);

• NuGet is a Visual Studio extension that makes it easy to add, remove, and update libraries and tools in Visual Studio projects that use the .NET Framework.
• If you develop a library or tool that you want to share with other developers, you create a NuGet package and store the package in a NuGet repository.
• If you want to use a library or tool that someone else has developed, you retrieve the package from the repository and install it in your Visual Studio project or solution. When you install the package, NuGet copies files to your solution and automatically makes whatever changes are needed, such as adding references and changing your app.config or web.config file.
• If you decide to remove the library, NuGet removes files and reverses whatever changes it made in your project so that no clutter is left.
