Are there any solutions for purchasing items in app (I'm Korean and stripes are not supported in Korea)

Hello.
I’m making web-app for beauty commerce platform. I’m going to wrap my web with NATIVELY and deploy to Appstore, Playstore. I have to make function to purchase thing in my app(not purchasing at Appstore or Playstore, but in app). I was thinking about using STRIPES but they dont support for Korea right now. So I’m looking for other solutions for purchasing. Are there any solutions for purchasing function?
