Shopping portals for eBay no longer work for third-party gift card purchases since a few months ago. The one portal that remained was the iBotta app. They were paying 2%, then lowered it to 1%, and consistently tracked gift card purchases on eBay.
Yesterday, iBotta overhauled their app design. They also added terms excluding any kind of gift card from earning cash back on eBay.
No cash back will be earned on the purchase of gift cards or gift certificates of any kind
A friend made a gift card purchase yesterday using iBotta and the app denied the cash back. “Unfortunately, your purchase did not qualify for cash back.”
Ibotta made a positive change to the app that you no longer have to Unlock Rebate for online  purchases – it now works more like an ordinary online shopping portal. We’ve updated our iBotta review to reflect that change.
