Can I mix a Stripe in-app purchase with native App Store and Google Play billing?

Yes. Adapty merges StoreKit, Play Billing, and in-app purchase Stripe events into one profile, so users keep a single active subscription no matter where they pay.

Does Adapty sync refunds for Stripe Apple in-app purchase events?

Full refunds hit Stripe first; Adapty receives the webhook and removes entitlements in real time, keeping iOS, Android, and web access in sync.

Does Adapty handle proration or partial refunds for a Stripe in-app purchase flow?

Not yet. Adapty records the final charge amount only. If you need mid-cycle proration today, apply the adjustment in your backend and push the net total to Adapty via its server API.

Can I use tiered or metered prices with my Stripe in app purchase iOS integration?

Currently Adapty supports Flat-rate and Package price types. Tiered or metered billing isn’t recommended because quantity-based events don’t map cleanly to mobile entitlements.

Is it ok to rely on customer email instead of customer_user_id for a stripe ios in app purchase setup?

Email works as a fallback, but Adapty strongly recommends passing the same customer_user_id you use inside your app. A stable ID guarantees instant cross-platform unlocks and avoids mismatches caused by “hide-my-email” aliases.

“We’ve tested more than three hundred paywalls in the space of four months. Adapty allows testing basically any element of the paywall, and we took advantage of that. We’ve tested them all: products, title text, CTA buttons, images, videos etc. With Adapty’s A/B testing, we managed to double our monthly revenue. I wasn’t sure if one instrument could make such an impact, but I witnessed it myself.”
