Enable purchases by using paywalls in Unity SDK

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

• Products – anything users can buy (subscriptions, consumables, lifetime access)
• Paywalls are configurations that define which products to offer. In Adapty, paywalls are the only way to retrieve products, but this design lets you modify offerings, pricing, and product combinations 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.

Adapty offers you three ways to enable purchases in your app. Select one of them depending on your app requirements:

Implementation	Complexity	When to use
Adapty Paywall Builder	✅ Easy	You create a complete, purchase-ready paywall in the no-code builder. Adapty automatically renders it and handles all the complex purchase flow, receipt validation, and subscription management behind the scenes.
Manually created paywalls	🟡 Medium	You implement your paywall UI in your app code, but still get the paywall object from Adapty to maintain flexibility in product offerings. See the guide.
Observer mode	🔴 Hard	You already have your own purchase handling infrastructure and want to keep using it. Note that the observer mode has its limitations in Adapty. See the article.

The steps below show how to implement a paywall created in the Adapty paywall builder.

If you don't want to use the paywall builder, see the guide for handling purchases in manually created paywalls.

To display a paywall created in the Adapty paywall builder, in your app code, you only need to:

1. Get the paywall: Get the paywall from Adapty.
2. Display the paywall and Adapty will handle purchases for you: Show the paywall container you've got in your app.
3. Handle button actions: Associate user interactions with the paywall with your app's response to them. For example, open links or close the paywall when users click buttons.

1. Get the paywall

Your paywalls are associated with placements configured in the dashboard. Placements allow you to run different paywalls for different audiences or to run A/B tests.

To get a paywall created in the Adapty paywall builder, you need to:

1. Get the paywall object by the placement ID using the GetPaywall method and check whether it is a paywall created in the builder using the hasViewConfiguration property.

2. Create the paywall view using the CreateView method. The view contains the UI elements and styling needed to display the paywall.

important

To get the view configuration, you must switch on the Show on device toggle in the Paywall Builder. Otherwise, you will get an empty view configuration, and the paywall won't be displayed.

Adapty.GetPaywall("YOUR_PLACEMENT_ID", (paywall, error) => {
  if(error != null) {
    // handle the error
    return;
  }
  
  // paywall - the resulting object
});

var parameters = new AdaptyUICreateViewParameters()

AdaptyUI.CreateView(paywall, parameters, (view, error) => {
  // handle the result
});

info

This quickstart provides the minimum configuration required to display a paywall. For advanced configuration details, see our guide on getting paywalls.

2. Display the paywall

Now, when you have the paywall configuration, it's enough to add a few lines to display your paywall.

To display the paywall, use the view.present() method on the view created by the СreateView method. Each view can only be used once. If you need to display the paywall again, call createPaywallView one more to create a new view instance.

Unity

view.Present((error) => {
  // handle the error
});

info

For more details on how to display a paywall, see our guide.

3. Handle button actions

When users click buttons in the paywall, the Unity SDK automatically handles purchases and restoration. However, other buttons have custom or pre-defined IDs and require handling actions in your code.

For example, your paywall probably has a close button and URLs to open (e.g., terms of use and privacy policy). So, you need to respond to actions with the Close and OpenUrl IDs.

tip

Read our guides on how to handle button actions and events.

Unity

public void PaywallViewDidPerformAction(
  AdaptyUIView view, 
  AdaptyUIUserAction action
) {
  switch (action.Type) {
    case AdaptyUIUserActionType.Close:
      view.Dismiss(null);
      break;
    case AdaptyUIUserActionType.OpenUrl:
      // Open the URL using Unity's Application.OpenURL
      Application.OpenURL(action.Value);
      break;
    default:
      break;
  }
}

Next steps

Your paywall is ready to be displayed in the app.

Now, you need to check the users' access level to ensure you display a paywall or give access to paid features to right users.

Full example

Here is how all those steps can be integrated in your app together.

using System;
using UnityEngine;

public class PaywallManager : MonoBehaviour
{
    [SerializeField] private string placementId = "YOUR_PLACEMENT_ID";
    
    private AdaptyUIView currentPaywallView;
    
    void Start()
    {
        GetAndDisplayPaywall();
    }
    
    private void GetAndDisplayPaywall()
    {
        Adapty.GetPaywall(placementId, (paywall, error) => {
            if (error != null) {
                Debug.LogError("Error getting paywall: " + error.Message);
                return;
            }
            
            if (paywall.hasViewConfiguration) {
                CreateAndPresentPaywallView(paywall);
            } else {
                Debug.LogWarning("Paywall was not created using the builder");
            }
        });
    }
    
    private void CreateAndPresentPaywallView(AdaptyPaywall paywall)
    {
        var parameters = new AdaptyUICreateViewParameters();
        
        AdaptyUI.CreateView(paywall, parameters, (view, error) => {
            if (error != null) {
                Debug.LogError("Error creating paywall view: " + error.Message);
                return;
            }
            
            currentPaywallView = view;
            
            view.Present((presentError) => {
                if (presentError != null) {
                    Debug.LogError("Error presenting paywall: " + presentError.Message);
                    return;
                }
                
                Debug.Log("Paywall presented successfully");
            });
        });
    }

            case AdaptyUIUserActionType.Close:
                Debug.Log("Close button pressed");
                view.Dismiss(null);
                break;
            case AdaptyUIUserActionType.OpenUrl:
              Application.OpenURL(action.Value);
              break;
            default:
                break;
        }
