I found some answers about this talking about some API, but I dont understand what that is. Is there a way to have a cell in excel with the current price of an item in the steam market and having that price update?
Please excuse my lack of knowledge:3.
First of all, your question isn't really a solid question and what a i mean with that is you talk very briefly about your problem but heck lets go
So first of all i would suggest you learning python if you haven't already learned it.
Then look for some tutorial of "how to use a web api" and research the requests library for python.
All done?
Good, now steam has some kind of api, which i never looked into really but here:
https://steamcommunity.com/market/priceoverview/?appid=730¤cy=3&market_hash_name=AK-47 | Elite Build (Field-Tested)
This gives you some stats about the weapon in this case its the AK Elite Build Field-Tested, The ouput will have just some data but enough, there will be the lowest price available for you. (lowest steam market offering for the item you specified in the "url".
