How to create application and generate access token?

The Facebook API requires authentication, specifically requests made on behalf of a user. Authenticated requests require an “access_token”. Access tokens may expire at any time in the future. Follow the given steps to generate an access token:

• Create new application
• Generate access token

Create new application

1. The following steps are used to register new application: Go to Facebook developer window. Register a new app by clicking “add a new app” menu in my apps dropdown menu present in header of Facebook developer account.
   

1. Enter the relevant information in application registration page and click “create app ID”.
   

1. After registration, a new app will be created with unique app ID and app secret. This app ID and app secret is used to get “access_token”.
   

Generate access token

To generate an app access token, make a graph API call,

GET /oauth/access_token?client_id={app-id}&client_secret={app-secret}&grant_type=client_credentials

This call will return an app access token, used in place of a user access token to make API calls as noted above.

There is another method to make graph API calls that doesn’t require a generated app access token. You can pass your app ID and app secret as the access_token parameter when you make a call,

https://graph.facebook.com/endpoint?key=value&access_token=app_id

app_secret
