Paypal Integration With Salesforce

1. Need to set up developer account in paypal
http://developer.paypal.com
nd create one account there. After creating, login there only. In the left menu you will find "Test Accounts" link. Click on that.
From the right side screen, you can create multiple test accounts.
For testing purpose generally you need two type of accounts. One is "Seller" and one is "Buyer". Its always better to create preconfigured accounts.

Creating Calendar event in Google from salesforce using Oauth

To Create a calendar event in google you need to set up OAuth between Salesforce and Google.

You need to create an app in Google. Navigate to
https://code.google.com/apis/console and create a project.

Vf Page:
<apex:page controller="CalenderConnect">
<apex:form >
  <apex:commandButton value="Google" action="{!doGoogleConnectCall}"/><br/>
</apex:form>
</apex:page>

Accessing FaceBook from Salesforce

Here is an example to get connected to Facebook and get the Facebook information

Need to create 2 visual force pages and 2 controllers.

Before creating the vf pages and controller you need to create an app in facebook.
To create an app navigate to
https://developers.facebook.com/
and create an app you will get Client Id and secret. Paste those values in FBRedirectURI class .

Vf Page:
<apex:page controller="FaceBookApp" showHeader="false" sidebar="false" action="{!getAccessToken}">
</apex:page>

Controller:
public class FaceBookApp {
    String ClientId='Your Facebook App Id';
    public PageReference getAccessToken() {
        PageReference pgReference=new PageReference('https://graph.facebook.com/oauth/authorize?client_id='+ClientId+'&redirect_uri=https://ap1.salesforce.com/apex/facebook/FaceBookRedirecturi&scope=user_about_me&state=/FaceBookApp');
pgReference.setRedirect(true);
return pgReference;
        pgReference.setRedirect(true);
        return pgReference;
    }
}

Vf Page :
<apex:page controller="FBRedirectURI" action="{!init}"  sidebar="false" showHeader="false">
<html>
<body>
<h2 style="align:middle">Congratulations, You have added the app to your account </h2>
</body>
</html>
</apex:page>

Controller:
public class FBRedirectURI {
    public PageReference init() {
         String ClientId='Your Facebook App Id';
         String Secret='Your Facebook App Secret';
        try{
            if (! ApexPages.currentPage().getParameters().containsKey('code')) {
                ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.FATAL, 'Missing code parameter');
                ApexPages.addMessage(msg);
            }
        String code = ApexPages.currentPage().getParameters().get('code');
        System.debug('Facebook OAuth Step 2 - code:'+code);
        String state =  ApexPages.currentPage().getParameters().get('state');
        System.debug('state:'+state);
        String tokenURI = 'https://graph.facebook.com/oauth/access_token?client_id='+ClientId+'&redirect_uri='+
            +'https://ap1.salesforce.com/apex/FaceBookRedirecturi'+

        if ( amp == -1 ) {
            accessToken = response.substring(acc + 13, response.length());
        } else {

        System.debug('API RESP: '+response);
