RevenueCat does not require server notifications from the Galaxy Store, however enabling them can speed up webhook and integration delivery times and reduce lag time for [Charts](/dashboard-and-metrics/charts).

:::warning Receipt must exist in RevenueCat
Galaxy Store server notifications only work if the receipt exists in RevenueCat when the event is dispatched from Galaxy Store. If the receipt doesn't exist, the notification will be ignored.

## Setup Instructions

1. Navigate to your **Galaxy app settings** in the RevenueCat dashboard by selecting your app from **Apps & providers** > **Configurations**.

2. Expand the **Galaxy Server to Server notification settings** section and copy the endpoint provided under **Samsung IAP Instant Server Notification Service URL**.
