Is there a way to avoid In-App (30%) fee for any purchases in iOS?

Question

I have an app which has some purchase option. However, I don't want to make it through the app itself. For that, I already have a website for the purchase.

So can I create a redirection page from my app to the respective webpage?

Will my app get rejected?

or is there a better solution?

Answer 1

It depends on what you are selling, if you are offering "Physical Goods and Services Outside of the App" you cannot use IAP and must use something else as described in the App Store Review Guidelines

3.1.5 (a) Physical Goods and Services Outside of the App: If your app enables people to purchase goods or services that will be consumed outside of the app, you must use purchase methods other than in-app purchase to collect those payments, such as Apple Pay or traditional credit card entry.

If not then you must use IAP and will be charged a 30% fee. However, if you are offering subscriptions this rate will drop down to 15% for users who have been subscribed for over 1 year. Check out Offering Subscriptions for more info if you are interested.

Answer 2

There isn’t any,

According to Apple’s official guidelines

If you want to unlock features or functionality within your app, (by way of example: subscriptions, in-game currencies, game levels, access to premium content, or unlocking a full version), you must use in-app purchase. Apps may use in-app purchase currencies to enable customers to “tip” digital content providers in the app. Apps and their metadata may not include buttons, external links, or other calls to action that direct customers to purchasing mechanisms other than in-app purchase.

You must use in-app purchases and Apple’s official API’s, if it’s not a physical item

Otherwise your app will be rejected
