Question: I read this [article](https://stackoverflow.com/questions/7832533/request-dialog-using-facebook?answertab=votes#tab-top).

So, I tried it and I put a number in the data property.

```
FB.ui({
    method: 'apprequests',
    message: 'Come join me and play at MyWebSite!',
    data: '12345',
    redirect_uri: 'myWebSite'
});

```

I get the `request_ids`, but how do I get the data part (the 12345 number)?.

Answer: 
Did you try Facebook's documentation too?

<https://developers.facebook.com/docs/requests/> has more documentation; if a `data` parameter was added in the call to the requests dialog, the same value should also be there when requesting the Request details via the API (i.e. a call to `/REQUEST_ID`)
See the facebook developer site documentation for more details
<http://developers.facebook.com/docs/reference/dialogs/requests/>

Note:

`data`:Optional, additional data you may pass for tracking. This will be stored as part of the request objects created. The maximum length is 255 characters.
