This repository contains core files for all Java sdks.

Prerequisites:

• Java JDK-1.5 or higher
• Apache Maven 3 or higher

To build this application:

• Run 'mvn install' to build jar file.

Core Testing:

• Run 'mvn test' to run the test cases for all the core classes.
• Test reports are generated in testReport folder.

Core Logging:

• For logging - java.util.logging has been used. To change the default configuration, edit the logging.properties file in 'jre/lib' folder under your JDK root.

Core Configuration:

The core uses .properties format configuration file. Sample of this file is at 'src/test/resources/'. You can use the 'sdk_config.properties' configuration file to configure

• Mode is specified using the parameter name 'mode' with values 'sandbox' or 'live', if specified 'service.EndPoint' parameter is not required and the SDK choses the sandbox or live endpoints automatically.

• (Multiple) API account credentials, by appending a '.' (dot) character and the service name to 'service.EndPoint' parameter.

• HTTP connection parameters, if certain connection parameters are not specified, the SDK will assume defaults for them.

• Service configuration.

OpenID Connect Integration

• Redirect your buyer to Authorization.getRedirectUrl(redirectURI, scope, configurationMap); 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

    Map<String, String> configurationMap = new HashMap<String, String>();
    configurationMap.put("clientId", "...");
    configurationMap.put("clientSecret", "...");
    configurationMap.put("service.EndPoint", "https://api.paypal.com/");
    APIContext apiContext = new APIContext();
    apiContext.setConfigurationMap(configurationMap);
    ...
    CreateFromAuthorizationCodeParameters param = new CreateFromAuthorizationCodeParameters();
    param.setCode(code);
    Tokeninfo info = Tokeninfo.createFromAuthorizationCode(apiContext, param);
    String accessToken = info.getAccessToken();

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

    Map<String, String> configurationMap = new HashMap<String, String>();
    configurationMap.put("clientId", "...");
    configurationMap.put("clientSecret", "...");
    configurationMap.put("service.EndPoint", "https://api.paypal.com/");
    APIContext apiContext = new APIContext();
    apiContext.setConfigurationMap(configurationMap);
    ...
    Tokeninfo info = new Tokeninfo();
    info.setRefreshToken("refreshToken");
    UserinfoParameters param = new UserinfoParameters();
    param.setAccessToken(info.getAccessToken());
    Userinfo userInfo = Userinfo.userinfo(apiContext, param);

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

    Map<String, String> configurationMap = new HashMap<String, String>();
    configurationMap.put("clientId", "...");
    configurationMap.put("clientSecret", "...");
    configurationMap.put("service.EndPoint", "https://api.paypal.com/");
    APIContext apiContext = new APIContext();
    apiContext.setConfigurationMap(configurationMap);
    ...
    CreateFromRefreshTokenParameters param = new CreateFromRefreshTokenParameters();
    param.setScope("openid"); // Optional
    Tokeninfo info = new Tokeninfo // Create Token info object; setting the refresh token
    info.setRefreshToken("refreshToken");

    info.createFromRefreshToken(apiContext, param);
