Is it possible to send "like/unlike" requests without clicking on the frame?

Question

In contact with

Good day.
Let's assume that the page has a like from VKontakte and a regular element, clicking on which should send a "Like/Unlike" request (Roughly speaking, VK like with its own appearance).
The goal is to like/dislike without clicking on the original like.
Is it possible to make such requests? With or without an API. I dug into the documentation, but did not find the answer.

Answer 1

I think you have a mess in your head.
vk.com/dev/likes.add
without VK API - no.

Answer 2

Hang the widget, let it follow the cursor, set z-index and transparency. As a result, we wait for the click, as soon as it is made, the like is put. Without this click

Answer 3

1) I do not know if it is possible to make such requests from sites using the API.
Although you can just buy a full-fledged server, upload a desktop application to it, and let the back-end of the site lying on the server let it pull (launch) this application and it likes the Server
- this is the same desktop from its side
2) It is possible without the VK API.
VK, like any other site, has a back-end. And this is not the VK API, it has its own back-end.
When a user works with VK, the browser sends HTTP requests to this back-end.
And with the help of a sniffer like Fiddler, you can track these requests and then simulate them in any desktop / server programming language (but NOT in JS, because cross-domain requests cannot be made on it - but this is not critical). Simulate client (browser) actions.
Some sites don't have an API at all. This is the only way bots write for them.
