@NickPye, Welcome onboard!
You are right about Sparkle search not being able to search the Ecwid Store. Have you used embed code you got from Ecwid via your account?, or did you use Sparkle’s monitization function?
If you check what Sparkle3 has onboard it can help you with search of your Ecwid Store…
@NickPye, Ok makes sense.
If you place a “Payment” element on your canvas you’ll notice in the right hand panel options you can select and one of them being an Ecwid search box, please see screenshot…
