Parsing comments and messages in classmates?

Question

PHP

Greetings. The problem is this: you need to periodically receive new messages and new comments on the photo (with photo). I tried to work with apiok but everything stalled on receiving messages (not enough rights), support is not responding.
Question: Are there any tools to solve this problem? Or which way to dig?

in general, the idea is this, with a new message / comment, send this message via sms / telegram to the phone to managers.
