Getting Facebook Contacts in 4 Simple Steps

Here I am giving you simple demonstration about how to import contacts from Facebook.

Step 1: Create a facebook app at https://developers.facebook.com/

 I have created a try app which I am using to get my FB contacts:

client_id=345255442153376

Client_Secret=dba2c658b768480a616d7fc7f198e725  &

redirect_uri=http://localhost:6209/default.aspx

After completing step 1 go to step 2.

Step 2:  Browse to the below url in browser window:

https://www.facebook.com/dialog/oauth?client_id=345255442153376&redirect_uri=http://localhost:6209/default.aspx&scope=publish_stream

it will ask for permissions click Allow Button:

This will give u a window like below which is having code=some_code like query string in browser window we need to use this code further.

http://localhost:6209/default.aspx?code=AQDAklJNfyMiZvOSUZBCHgw0KTwIQoJRPoN0tTJ90CJL6Xb547wHRaKlem81WWQsg_59o-OI9-VpoF7O0UQ09wAqn6AUV0QX7CYreYvlIQjPS4D5ptoUxJep1hJ5CGgo9zCayyaS5W8emja39bUYas4SvdsR9vLLVnGOCDDGgmvrO4e0enIh5nXchXbb3JxJw6EDz4Cqf2OSzunCLLWEZxux#_=_

We need to use code 

(code=AQDAklJNfyMiZvOSUZBCHgw0KTwIQoJRPoN0tTJ90CJL6Xb547wHRaKlem81WWQsg_59o-OI9-VpoF7O0UQ09wAqn6AUV0QX7CYreYvlIQjPS4D5ptoUxJep1hJ5CGgo9zCayyaS5W8emja39bUYas4SvdsR9vLLVnGOCDDGgmvrO4e0enIh5nXchXbb3JxJw6EDz4Cqf2OSzunCLLWEZxux#_=)  in next step.

Step3 :  Now browse to the url in browser window:

https://graph.facebook.com/oauth/access_token?client_id=345255442153376&redirect_uri=http://localhost:6209/default.aspx&Client_Secret=dba2c658b768480a616d7fc7f198e725&code=AQASA2AICGdOzLUOa8CiTgnrJY0Seme7Jx8qNY95rnO2_DvqLxy31AQo3uMtNCAm__7qfofH4rQflmNY_W_RcRmO2NFsQMichY4tvqlgGQRtwag7zXO-Yb54MtUhx4jC1_u_PNfx0080yvln2NDn1txy2Qpt5dJB18aHKUTWuwsFvGKYxY-uPhFY2brklHcIzM_-svv2NZ3QWwqnHfG9_UVs#_=_

Note: we need to use same code which we have retrieved in step2.    

                               

This step will give you an access token as query string. Something likes this:

http://localhost:6209/default.aspx?access_token=AAACEdEose0cBAM3Dbomr0wlNsMySIa8QGavZB15onOZAGZBGi8bPLHLOZCl6HXVCTNO17sPLArfThihlAbosDlyfbFJyZAOh2EHVbWZB3WbKxAX1o5E9Gi

access_token= AAACEdEose0cBAM3Dbomr0wlNsMySIa8QGavZB15onOZAGZBGi8bPLHLOZCl6HXVCTNO17sPLArfThihlAbosDlyfbFJyZAOh2EHVbWZB3WbKxAX1o5E9Gi

Now we need to use this access i to get contacts in next step.

Step 4: Browse to the below url and it will give u contacts in Json format.

https://graph.facebook.com/me?access_token=AAACEdEose0cBAM3Dbomr0wlNsMySIa8QGavZB15onOZAGZBGi8bPLHLOZCl6HXVCTNO17sPLArfThihlAbosDlyfbFJyZAOh2EHVbWZB3WbKxAX1o5E9Gi/me/friends

Note: we need to use same access token which we have retrieved in step3. 

For implementing above code you need to use asp.net HttpRequest and HttpResponse Objects.
