Enable purchases in your custom paywall in iOS SDK

This guide describes how to integrate Adapty into your custom paywalls. Keep full control over paywall implementation, while the Adapty SDK fetches products, handles new purchases, and restores previous ones.

important

This guide is for developers who are implementing custom paywalls. If you want the easiest way to enable purchases, use the Adapty Paywall Builder. With Paywall Builder, you create paywalls in a no-code visual editor, Adapty handles all purchase logic automatically, and you can test different designs without republishing your app.

Before you start​

Set up products​

To enable in-app purchases, you need to understand three key concepts:

  • Products – anything users can buy (subscriptions, consumables, lifetime access)
  • Paywalls – configurations that define which products to offer. In Adapty, paywalls are the only way to retrieve products, but this design lets you modify products, prices, and offers without touching your app code.
  • Placements – where and when you show paywalls in your app (like main, onboarding, settings). You set up paywalls for placements in the dashboard, then request them by placement ID in your code. This makes it easy to run A/B tests and show different paywalls to different users.

Make sure you understand these concepts even if you work with your custom paywall. Basically, they are just your way to manage the products you sell in your app.

To implement your custom paywall, you will need to create a paywall and add it to a placement. This setup allows you to retrieve your products. To understand what you need to do in the dashboard, follow the quickstart guide here.

Manage users​

You can work either with or without backend authentication on your side.

However, the Adapty SDK handles anonymous and identified users differently. Read the identification quickstart guide to understand the specifics and ensure you are working with users properly.

Step 1. Get products​

To retrieve products for your custom paywall, you need to:

  1. Get the paywall object by passing placement ID to the getPaywall method.
  2. Get the products array for this paywall using the getPaywallProducts method.
import Adapty

func loadPaywall() async {
    do {
        let paywall = try await Adapty.getPaywall("YOUR_PLACEMENT_ID")
        let products = try await Adapty.getPaywallProducts(paywall: paywall)
        
        // Use products to build your custom paywall UI
    } catch {
        // Handle the error
    }
}

Step 2. Accept purchases​

When a user taps on a product in your custom paywall, call the makePurchase method with the selected product. This will handle the purchase flow and return the updated profile.

import Adapty

func purchaseProduct(_ product: AdaptyPaywallProduct) async {
    do {
        let purchaseResult = try await Adapty.makePurchase(product: product)
        
        switch purchaseResult {
        case .userCancelled:
            // User canceled the purchase
            break
        case .pending:
            // Purchase is pending (e.g., awaiting parental approval)
            break
        case let .success(profile, transaction):
            // Purchase successful, profile updated
            break
        }
    } catch {
        // Handle the error
    }
}

Step 3. Restore purchases​

Apple requires all apps with subscriptions to provide a way users can restore their purchases. While purchases are automatically restored when a user logs in with their Apple ID, you must still implement a restore button in your app.

Call the restorePurchases method when the user taps the restore button. This will sync their purchase history with Adapty and return the updated profile.

import Adapty

func restorePurchases() async {
    do {
        let profile = try await Adapty.restorePurchases()
        // Restore successful, profile updated
    } catch {
        // Handle the error
    }
}

Next steps​

Your paywall is ready to be displayed in the app.

Next, check whether users have completed their purchase to determine whether to display the paywall or grant access to paid features.
