TLSv1.2 Update

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. Click here for more information

A new mode has been created to test if your server/machine handles TLSv1.2 connections. Please use security-test-sandbox mode instead of sandbox to verify. You can return back to sandbox mode once you have verified.

PayPal Core SDK for .NET

The PayPal Core SDK is a foundational library used by all of PayPal's C# SDKs. This SDK provides functionality such as configuration, credential management, connection management, logging, etc. that are used by the other SDKs. This SDK is developed using .NET Framework 3.5 and should compile on later versions of the .NET Framework. The SDK is also distributed via NuGet.

Prerequisites

• Visual Studio 2005 or higher

Repository

This repository contains

• PayPal Core SDK Class Libraries for Visual Studio 2005, 2008, 2010, 2012, and 2013
• Visual Studio Test project for Visual Studio 2005, 2008, 2010, 2012, and 2013

OpenId Connect Integration

• 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 an access token, refresh token, id token combo

    Dictionary<string, string> configurationMap = new Dictionary<string, string>();
    configurationMap.Add("clientId", "...");
    configurationMap.Add("clientSecret", "...");
    configurationMap.Add("mode", "live");

    APIContext apiContext = new APIContext();
    apiContext.Config = configurationMap;

    ...
    
    CreateFromAuthorizationCodeParameters codeParams = new CreateFromAuthorizationCodeParameters();
    codeParams.SetCode("code");
    CreateFromAuthorizationCode token = TokenInfo.CreateFromAuthorizationCode(apiContext, codeParams);
    string accessToken = token.access_token;

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

    ...

    TokenInfo tokenInfo = new TokenInfo();
    tokenInfo.refresh_token = "refreshToken";
    UserInfoParameters userInfoParams = new UserInfoParameters();
    userInfoParams.SetAccessToken(tokenInfo.access_token);
    UserInfo userInfo = UserInfo.GetUserInfo(apiContext, userInfoParams);

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

    ...
    
    CreateFromRefreshTokenParameters refreshTokenParams = new CreateFromRefreshTokenParameters();
    refreshTokenParams.SetScope("openid"); // Optional
    TokenInfo tokenInfo = new TokenInfo(); // Create TokenInfo object; setting the refresh token
    tokenInfo.refresh_token = "refreshToken";
    
    tokenInfo.CreateFromRefreshToken(apiContext, refreshTokenParams);

Unit Tests

• Visual Studio Test C#.NET Project 2013, 2012, 2010, and 2008
