Foot locker shoe bot/twitter link grabber help!!

I would like to make my own Foot locker bot that can grab a twitter link that Foot locker Tweets, and automatically open a new tab where the bot will then add to cart (my size) in less than 10 seconds.

All I would have to do is checkout. The bot must be accessible to anyone with a username, that I can add or remove whenever I feel like because I am the ADMIN. The bot must be a chrome extension and an app that must be authorized by twitter for it to start monitoring Foot locker's twitter timeline for a specific KEYWORD.

The bot must have an option page. This is where I or anyone can edit to there specific need.

The option page must have the following:

SwooshSniperUsername:

Keyword:

Exclude:

Size:

Notification Email:

Notification me ?: [Yes] [No]

Refresh Unavailable Product Time:

Refresh Delayed Time:

[SAVE] <button.>

I really need help, if someone can help me step by step making this bot and how do I write the script for the specific function?

Thanks so much y'all
