Getting real-time Facebook Live comments from Webhook?

I am trying to write a program that can receive comments (as they are) in my Facebook Live videos. Having looked through Documents, I see the following text:

Reading comments and reactions

You can read comments in real time by polling a video report. To make this the most efficient way, so as not to exceed the Graph API speed limits, we recommend getting API updates through webhooks. You can also read reactions in real time by polling the edge of Reactions.

When I look at webhooks , I cannot find the documentation that says how often they are called. Do they call for every comment or for some predetermined interval?

In addition, webhooks callbacks run the risk of being received out of order. What is the best way to avoid missing messages?

Thanks.

As of 3/7/2017, you can get a warning about posting comments via webhook, but the comment itself is not sent in the request.

Apparently, they updated their documentation. They no longer recommend using webcams for live commentary. Now they suggest using a survey. https://developers.facebook.com/docs/videos/live-video/production-broadcasts#comments
