Navigate to your DroiX affiliate
There you can find your referral link, that looks something like
Your referral code is part after
?ref=, in this case
All you need is to copy that Referral code, open extension options, go to Platforms / Chinese / Other, and paste it in the DroiX field.
Then close options, find the product on DroiX you want to share and click on the extension icon. It will generate an affiliate link for that page. Then you can use bit.ly to shorten that link (if configured) or copy and share it.
