automatic posting boot with autohotkey and others

The website is commissioned by BBS to automatically develop a program to post content. 1. The title and contents must be editable. 2. The posting time must be adjustable. 3. The title and content of the posting must be adjustable (the same content must be updated from 10 to 100 times a day). 4. Once a post has been posted, you must delete the previously registered post. The website is a used merchandise trading site in Korean. I would like to create a program that will automatically post items on this site. The site can post posts and photos from the mobile version as well as the pc version. I can translate the Korean menu into English.
