How to find how a particular website works

Question

Im looking for a tool to find how particular websites work.

Before you answer, note that this isnt to learn how to build a website, this is to learn how to make programs to automate tasks on the website by sending GET,POST,etc requests.

You might call this a ‘bot’. Note: before this question raises your suspicions, I’m doing this for educational purposes and to find ways to automate tasks (in a good way, I’m not about to storm some website with fake users)

Answer 1

You're looking for a network packet capturing/sniffing tool (with SSL striping capabilities) like WireShark.

Answer 2

Using the built-in inspect tool?

- to check out the sites source code

Answer 3

@Manual any ideas on how to use this?

I'm trying to get data that a program can use. For example, a function could be to message 50 people automatically about an offer or make 20 codes automatically by just giving it functions to input the right GUIs and navigate to a place where it can do a specific function as in my examples

Answer 4

If the website is yours I recommend you implement an API, with that you could make the requests that you like from another program or access information that you have stored on the server

If the site is not yours you should look for how to pass HTML to JSON, which would be the closest thing. Although in this way you would not have access to too much information
