Question

Bots

Hello, look, I need to create a bot to which I will send a link to the TG channel on which the photos I need, then I will send the #hashtag that the photo I need to download has, it will automatically upload this photo to the database, after which I will have nothing left just click on the download button.
The bottom line is that I need to sort through the files in the cart and download them, help anyone, please.
Also, if there are any sites that can help guys in this way)))
