Create a Script / Program that places bets with normal functionality, what should be studied?

Question

Programming

Hello, in general, I need to implement the following: Create a program / script for betting on LIVE, the problem is that you can bet on LIVE every 60 seconds. I have a database of accounts and there is a balance, it is necessary that by pressing a button from all these accounts bets are placed on the event I have chosen. You need to be logged in to bet. (Through Tor/Chrome Personality went in, there is a delay until I go there, time will pass.) And in terms of complexity, I also want to add functionality - Total balance - Number of bets.
PS I don’t want to hire a freelancer, I want to study it myself

Answer 3

What server do you bet on?

Answer 4

If there is no need to run your applications on a server without an interface, i.e. for example, you can have a browser open, then you can use browser extensions (or just inject your script through the script console if the web application is a single page application), then you will have enough javascript application, as simple as a valenok.
For example, to fill the input field with text, you need to write something like $('css selector control').value='blablabla', press the button $('...').click(etc.)
The advantage of the approach is that the server will almost never be able to distinguish your application from the user (only statistics and behavioral analysis, that’s another task), and often, small changes in the code on the server require minimal or even no fixes in your automation scripts, compared to the curl approach (which requires you to completely retry web page requests to the server, this is usually more difficult).
The disadvantage is that the web browser requires more resources to work (even headless) so much that, for example, a hundred bots on one machine can no longer be pulled.
