Steam API. How to make a trading bot friends with Steam Guard?

Question

API

Problem: the bot is located on the site server and connected to steam, to display inventory information on the site and interact with users through the site interface. The problem is that the bot writes in the logs that the authorization was successful, but in fact the inventory is not displayed on the site. There are suspicions that the bot cannot bypass Steam Guard. Question-consequence - how to solve this problem? We can't opt ​​out of Steam Guard. They say it's risky.
Who sewed bots, tell me what to do with steam guard? The response code must be entered within 60 seconds. There are a couple of village ideas, but I want to be human.
Thank you.
