Google API V3 wrapper for Salesforce

Google API V3 for Salesforce

This project is an api wrapper for Google API V3.
Currently it contains only Calendar API.

Authentication

It supports OAuth2.0 Server Flow and Service Accounts authorization.

• https://developers.google.com/accounts/docs/OAuth2WebServer
• https://developers.google.com/accounts/docs/OAuth2ServiceAccount

Unfortunately, now Apex can not sign with SHA256withRSA.
So if you want to use Service Accounts authorization, you must prepare a sign server.

• https://github.com/shunjikonishi/sign-server

Sample code - Server Flow authrization.

GoogleOAuth oauth = new GoogleOAuth(
    'YOUR_CLIENT_ID.apps.googleusercontent.com',
    'YOUR_CLIENT_SECRET',
    GoogleCalendarService.SCOPE_READWRITE,//scope
    'https://c.na14.visual.force.com/apex/YOUR_REDIRECT_URI'
);
String loginUrl = oauth.getLoginUrl();
//ToDo Open loginUrl and get authorization code.
GoogleOAuth.AuthResponse auth = oauth.authenticate(code);

service = new GoogleCalendarService();
service.setAccessToken(auth.token_type, auth.access_token);

Sample code - Service Accounts authrization.

SignServer sign = new SignServer('https://YOUR-APPNAME.herokuapp.com/sign');
service = new GoogleCalendarService(sign);
JWT jwt = new JWT('[e-mail]');
service.authenticate(jwt);
