you can't download them that you post already automatically.
However, if you join in the chat room where bot's joined, bot can read photo/files/video and you can save it automatically somewhere you want.
I am new to this forum, please bear with me if I am asking repeative question and I just need some hint to firure the rest. Because I don't even kow hwere to start.
Here is m y question, I like to download the photo/files/video from my LINE chat to my computer, so I don't have to manually click and press save or whatever. In thay way, I will not miss the important info resides in the photo/video and etc so info will be saved automatically.
Please kindly advise, thank you very much.
