How-to-use-Hotmail-REST-API-to-import-contacts

Importing contacts using Hotmail API works in three steps:
1. Getting Request Token:

Use the following URL to request token form Hotmail.

 https://login.live.com/oauth20_authorize.srf?client_id=CLIENT_ID&scope=wl.signin+wl.basic+wl.contacts_emails&response_type=code&redirect_uri=REDIRECT_URL

2. Getting access token:

After the user successfully signs in and consents to the requested scopes, the Live Connect authorization web service uses the value of the redirect Uniform Resource Identifier (URI) to return the user to your site, and gives your app an authorization code as represented here by the string of characters that follow ?code=.

You can now use this authorization code to obtain an access token—the unique string of characters that allows your app to get a user's info from a service that is compatible with Live Connect. To request an access token, your app must include its client ID, a redirect URI, its client secret, the authorization code, and the grant_type parameter set to authorization_code, like this.

POST https://login.live.com/oauth20_token.srf
Content-type: application/x-www-form-urlencoded
client_id=CLIENT_ID&redirect_uri=REDIRECT_URL&client_secret=CLIENT_SECRET&code=AUTHORIZATION_CODE&grant_type=authorization_code 

3. Getting Contacts:

Use the following URL to request token form Hotmail.

https://apis.live.net/v5.0/me/contacts?access_token=YOUR_ACCESS_TOKEN;

With this you will get the data in following format. 

{

"data": [

{

"id": "contact.ece6f2d6000000000000000000000000",

"first_name": "ABC",

"last_name": "XYZ",

"name": "ABC XYZ",

"is_friend": false,

"is_favorite": false,

"user_id": null,

"email_hashes": [

],

"updated_time": "2013-09-02T07:16:22+0000",

"emails": {

"preferred": "ABC@xyz.com",

"account": null,

"personal": "ABC@xyz.com",

}

}

]

}

Here required emails are present along with email_hashes which you can easily use for sending mails.
