About Chrome Extension.

Question

thanks in Advance ...

Actually, I have made the Web Extention as like https://chrome.google.com/webstore/detail/honey/bmnlcjabgnpnenekpadlanbbkooimhnj?hl=en (hony)functionality but I have stuck in the last steps when coupon Auto applying.

I have to need to trigger Webpage event through Extention any event but can't be done yet.............

So please if have any idea about this please share with me.
