How does the marketplace work?

Question

CMS

Interested in the functionality of this site: market.csgo.com and others like it.
With what mono to implement such opportunities? in particular, they are interested in a BOT for a Steam account, which takes the item from the seller and automatically transfers it to the buyer upon payment. How can you write such a bot?

Answer 1

All of the above comments have nothing to do with this site. Although maybe in part.
I answer your question:
user registration/authorization is done using the Steam API ( steamcommunity.com/dev/apikey)
the bot is written on node.js ( https://nodejs.org/en/) + node-dota2 ( https:// github.com/RJacksonm1/node-dota2) OR node-csgo ( https://github.com/joshuaferrara/node-csgo) depending on which game you plan to code for.

Answer 2

1. We look: there is an API - we use the API.
2. If there is no API -> we write our client to execute requests (wrapper) in PHP (or similar) and interact with the site through it.

Answer 3

I advise you to read about the API.

Answer 4

How can such opportunities be realized?
How can you write such a bot?
In PHP it's as easy as shelling pears. Read the documentation. Write business logic. Ready.
