In this blog we will create our own app and with the help of our own appId and appSecret we will login and fetch some user related data also
So follow below steps to create your own facebook app
Step 1 – Login to developers facebook
Step 2 – Under my apps click on Add New App link
It will ask you to give display name and email and click on Create App ID button
Step 3 – Once app creation is done, you can see dashboard like below image
click on setting -> basic
so now you can see app id and app secret key.
Add Site URL (http://localhost:8080/) under website section.
click on Facebook Login -> Quickstart add website URL in Site URL text box and click on save
now we are ready to use this app
