Facebook Page Subscribed Apps

What the hell is this Subscribed Apps

Honestly, I don’t know. There is a documentation for it but it doesn’t even state what the hell is this Subscribed apps

https://developers.facebook.com/docs/graph-api/reference/v2.4/page/subscribed_apps

But if you look at the older documentation (v2.2), there is some descriptions on this subscribed apps

Subscribed Apps for a Facebook Page. This edge will allow you subscribe or unsubscribe an app to real time updates for a Page.

Apps that are in development mode will not receive real time updates.

A Page Access Token is required for all methods.

And, from my experience is, I’m using it to create a webhook from my Facebook Page to my application URL. So Facebook will sent live updates from my Page to my application.

View your page subscribed apps

I would reccomend using the ‘Graph Explorer’ tools for this.

developers.facebook.com > Tools & Support > Graph API Explorer

You will need to use ‘Page Token’ to make any request for subscribed_apps and that means you will need to have admin role in the page.

So, just choose GET request and use this url format

{page_id}/subscribed_apps

If you use the right token and have the sufficient access to the page, it will show all your page subscribed apps.

Add your app to your page subscribed_apps

So here goes the meat of the bussiness. To be able to receive live feeds from a page, my application will need to be added to the page’s subscribed_apps.

We will be using the same url in the Graph Explorer with the page you want to subscribed to token.

{page_id}/subscribed_apps

But instead of sending GET request, we will be sending POST request. So click on the GET dropdown and choose ‘POST’

If you just send it like that, there will be no error but Graph API Explorer default application is Graph API Explorer. You will need to use your application to send the POST request. To do this

1. Scroll to 'Graph API Explorer' title header
2. There will be a 'Application' text with dropdown besides it
3. Choose your application from the dropdown 

Now send the POST request again, still using the page you want to subscribed to token. There should be no error and when you send the same request using GET, your newly subscribed application should be listed.
