The application requires four parameters: identifier of the Facebook page, user access token and application's id and secret.
A unique identifier of the Facebook page you would like to post on. Can be found with findmyfbid.com.
The application id can be found on the application dashboard on developers.facebook.com.
To get the application secret you have to be in admin role of a page on which you would like to publish posts.
Go to the application's dashboard. The secret is placed on the main page of it.
To grab a user access token two calls have to be made to the Facebook Graph API:
- the first one for an authentication code:
GET https://www.facebook.com/dialog/oauth?client_id={app-id}&redirect_uri={redirect-uri}&scope=manage_pages,publish_pages - the second one to change the code to access user token:
GET https://graph.facebook.com/oauth/access_token?client_id={app-id}&redirect_uri={redirect-uri}&client_secret={app-secret}&code={code}
{redirect-uri} can be anything based on App Domain defined on the application settings page.
Keep in mind that call for a Page Access Token uses appsecret_proof to protect the request. For more information about securing request look here.
