How to check if a particular user has left a comment in a widget on a website?

Question

In contact with

I inserted the VK comments widget ( https://vk.com/dev/Comments ) to the site.
I want to check if some user left a comment there.
Can this be done without requesting all comments via the https://vk.com/dev/widgets.getComments method (limit is 200 comments per request)?

Answer 1

only via https://vk.com/dev/widgets.getComments
Use https://vk.com/dev/execute and you can call the method 25 times in one request
