# PaymentMethodBinding

A binding that makes payment methods available in apps for an Apple Account.

```
struct PaymentMethodBinding
```

## Overview

This functionality is available only to eligible apps with server entitlements. The initializer [`init(id:)`](/documentation/StoreKit/PaymentMethodBinding/init(id:)) throws an error if your app doesn’t have the appropriate entitlement to use this API, or if the user isn’t eligible.

> Important:
> The ``doc://com.apple.storekit/documentation/StoreKit/PaymentMethodBinding/init(id:)`` and ``doc://com.apple.storekit/documentation/StoreKit/PaymentMethodBinding/bind()`` methods may display a system prompt that asks users to authenticate with their Apple Account. Call these methods only after an explicit user action, like tapping or clicking a button.

Initialize this structure using the in-app binding identifier that your server receives from the Apple server when your server initiates payment method binding. Call the [`bind()`](/documentation/StoreKit/PaymentMethodBinding/bind()) method to prompt users to confirm adding the payment method and making it their primary payment method.
