How to use VK API namely board.createComment via PHP?

Question

PHP

Greetings!
I want to automate the placement of a comment in several discussions of my group by means of sending a form from my site, where the group ID, discussion and the text itself will be indicated.
I took as a basis/instruction: https://habrahabr.ru/post/265563/
Created a standalone, used the application ID, got a token, but the result can not be overcome:
"error":{"error_code":15,"error_msg": "Access denied: no access to call this method","request_params":[{"key":"oauth","value":"1"},{"key":"method","value":"board .createComment"},{"key":"group_id","value":"group_id"},{"key":"topic_id","
_api.vk.com/method/board.createComment?group_id=group_id&topic_id=discussion_id&message=test_message&v=5.62&access_token=3e55...ab9d0
Please tell me how this request is made, I don't make friends with the API myself.

Answer 1

"no access to call this method" as if hint)))
When receiving a token, the necessary rights are indicated. You need to add the desired one(s).

Answer 2

That's right - I did not give the correct access rights, I redid it again carefully - everything turned out!)
