Getting an App’s 4-1-1

Problem

Is there any way for me to retrieve the general public information about an app?

Solution

Use the Application.getPublicInfo() method, and pass in any one of the following properties for the target app:

• application_id

• api_key

• application_canvas_name

Let’s say, for example, that you want to retrieve some information about the Zerofootprint Calculator. All three of the following will return the same array:

$appId = $facebook->api_client->application_getPublicInfo('8653633892');
$appAPI = $facebook->api_client->application_getPublicInfo
('d41570392c4b0d08a794f4a66b91a2a9');
$appCanvas = $facebook->api_client->admin_getPublicInfo('zfcalculator');

Discussion

The returned array includes the properties in Table 9-6.
