App Setup
These settings decide how receipts are processed and how user inventory is stored.
Open an application from Applications and select Edit in the top right corner.

General

| Field | Description |
|---|---|
YOUR APPLICATION ID | Created with the application and cannot be changed. Your app sends receipts to this identifier. |
NAME | Used to identify the application in your dashboard. Changing it has no effect on validation. |
USER BEHAVIOUR | Whether purchases are tied to a user, and how strictly. See User Storage. Requires a paid plan. |
WEBHOOK | Your own endpoint, called after every successful validation. See Server Webhook. Requires a paid plan. |
Platforms

Each store has its own tab. Fill in only the stores you sell on, and follow that store's page under Store Setup for where each value comes from.
| Field | Description |
|---|---|
BUNDLE ID | Your application identifier as registered on that store. Google Play and the App Store only. |
LICENSE KEY | The private key used to reach the store's validation API. |
ACCOUNT ID | The account the key belongs to. Apple splits this into Issuer Key and KID Key. |
WEBHOOK ID | PayPal only. Identifies the notifications PayPal sends us about subscriptions. |
PayPal keeps Sandbox and Production values side by side, because its two environments use separate credentials.
danger
Keep these values up to date. If a bundle identifier or key no longer matches what the store expects, every receipt sent to this application will fail validation.
