RevenueCat doesn't require server notifications from Amazon Appstore for most subscription updates. Configuring them can still speed up webhook and integration delivery times and reduce lag time for [Charts](https://www.revenuecat.com/docs/dashboard-and-metrics/charts). If you sell one-time purchases, set up Amazon Appstore Real-time Notifications so refunds update in RevenueCat automatically. Without them, a refund might only appear after the Customer opens the app again and purchases sync.

:::warning\[Receipt must exist in RevenueCat]
Amazon Appstore Real-time Notifications only work if the receipt exists in RevenueCat when the event is dispatched from Amazon Appstore. If the receipt doesn't exist, the notification will be ignored.

## Setup Instructions

1. Navigate to your **Amazon app settings** in the RevenueCat dashboard by selecting your app from **Project Settings > Apps**.
2. Expand the **Amazon Real-time Notifications settings** section and copy the endpoint provided under **Amazon Real-time Notifications URL**.

7. In the RevenueCat dashboard, you should see a **Last received at** timestamp for the endpoint too.

## Troubleshooting

If you don't see the **Verified** label in the Amazon Appstore Console, confirm that you copied the correct URL from the RevenueCat dashboard and click **resend** to try again.
