Whop recently emailed creators to say its older built-in checkout stops working on October 21, 2026. If you got that email and sell anything in an Overskill app, here's what it means for you.
The short version
- New apps are already fine. Apps started recently on Overskill use Whop Elements, the checkout Whop is keeping. The email needs no action for those apps. (A copy of an older app keeps the older app's checkout.)
- Some older apps still use the older checkout. After October 21, customers won't be able to pay in those apps until they're moved over.
- You don't need to rebuild anything. Open the app in the editor and click Upgrade checkout in the yellow note above the chat. It moves an older app to Whop Elements safely.
- Apps that don't sell anything won't break. If you plan to add a checkout to an older app, upgrade it first.
How to tell which checkout your app has
Open the app in the editor and ask the AI:
Does this app use Whop Elements or the older Whop checkout?
It reads your app's own record and tells you which checkout the app is set up with. If it says the older checkout and your app takes payments, your app needs the upgrade. You'll also see a yellow note about your checkout above the chat. If your app doesn't sell anything yet, nothing breaks now, but upgrade before you add a checkout.
A note if you've asked before: the AI used to say an older checkout was session-based
and therefore the newer version. That was wrong. Session-based is not the same as Whop Elements. If the AI says your app uses the older checkout, the upgrade is for you.
What to do if your app uses the older checkout
Click Upgrade checkout before October 21. Open the app in the editor. Apps that need the upgrade show a yellow note about your checkout above the chat. Click Upgrade checkout and the AI moves your checkout to Whop Elements. You can follow along in the chat. The upgrade is free for apps made before September 26, 2026. A copy made after that uses your credits, and the note tells you which applies.
Then test it and publish. The upgrade changes your preview, not your live app. Test the checkout in the preview, then click Publish. Until you publish, your live app keeps the older checkout.
Please don't ask the AI to switch your checkout by hand. A hand-made switch can leave your app half on the old checkout and half on the new one. Then a customer could pay and still look unpaid, so they wouldn't get access to what they bought. The AI won't do that switch for you. That's on purpose, not a bug. The Upgrade checkout button changes everything together, so payments and access stay in step.
Before you publish, run one test purchase to confirm buyers get in. See Test your checkout without paying.
What if I don't see the note, or the button says to contact support?
The note only shows when the app's code uses the older checkout. If your app sells things and the AI says it uses the older checkout but you don't see the note, or the button asks you to contact support, reach out through the help panel in the editor. Tell us which app it is, and we'll check it for you.
If the button asks you to reconnect payments first, reconnect them in the app's payments settings, then click Upgrade checkout again.
