How can I get all the comments on the posts of the public page vk.com?

Question

JavaScript

I am the admin of the VK public and would like to make a small web dashboard with all the fresh comments of the group.
How can this be done through the VK API?

newsfeed.getComments doesn't work.

Answer 1

New comments can be collected using the callback api.
Already existing comments cannot be retrieved at once. Only bypassing posts with wall.getComments
