How to authorize Vkontakte and open a page in a browser?

Question

In contact with

I want to write a script that will open the VK page in the browser according to the data entered in the code (login and password).
I don’t understand in which direction to think, such as through api or parsing. Does anyone have any ideas or a proven method?

Answer 1

Yes, you can parse, or you can use the API

Answer 2

If you parse, you have to mimic user behavior. Here it will be easier to use something like Selenium.
In general, read the API docs. If they allow you to solve your problem, then use them, it will be more reliable.
