facebook - Graph API direct message for page: how to retrieve link to attached file -


i need store link file attached direct message (for page, retrieved "/conversations"). how can that?

i know how link of image. json-object image ("attachments") contains tag "image_data", contains tags "url" , "preview_url" accessing image.

for attached files (in case e.g. pdf), fb sends "id", "mime_type", "name" , "size", no additional data. example:

"id": "m_id.158623824339344"  .... "attachments": {     "data": [      {         "id": "7b84fd4c0f18fb4060ae0fe0dcfeb42e",         "mime_type": "application/pdf",         "name": "attachment1.pdf",         "size": 80798       }     ]  }

but when log fb user , click attachment in browser, link:

https://www.facebook.com/ajax/messaging/attachment.php?attach_id=<attach_id>&mid=id.<mid>&pageid=<pageid>&ext=<ext>&hash=aqcafpyezj2psjrk

by trial , error found out possible access file without "hash" , "ext"-part. means in theory able generate link in application ("attach_id" , "mid" provided message , know pageid).

but seems unreliable. link might change anytime, breaking application.

i searched lot couldn't find documentation this. know better solution? or can point me documentation regarding issue?

thanks lot!
