# What does the Google Play notification ONE_TIME_PRODUCT_PURCHASED mean?

The Google Play notification ONE_TIME_PRODUCT_PURCHASED means a customer bought a one-time product.

## Quick facts

| | |
|---|---|
| Notification | `oneTimeProductNotification.notificationType` 1, `ONE_TIME_PRODUCT_PURCHASED` |
| Where | Google Play real-time developer notifications (Pub/Sub, `DeveloperNotification`) |
| Sent by | Google Play, as a Cloud Pub/Sub push to your endpoint |
| What Google says | A one-time product was successfully purchased by a user. |

## What triggers it

- A customer completed the purchase of an in-app product.
- Google sends it only if you chose to receive one-time product purchase events when you set up notifications.
- The message carries the `sku` and the `purchaseToken`.

## What your server should do

1. Do not trust the message for the state. Google says a notification only tells you the purchase state changed; call the Google Play Developer API (`purchases.subscriptionsv2.get`) with the purchase token to get the full state.
2. Call the products API with the `sku` and token, check the purchase state, and deliver the item once.
3. Acknowledge or consume the purchase so Google does not refund it.
4. Key delivery on the order so a repeat message does not give the item twice.
5. Answer 2xx once you have handled the message, and skip a `messageId` you have seen: Google recommends checking the uniqueness of message IDs so a redelivery does not make a second API call.

## Example

```javascript
// A Pub/Sub push body: the notification is base64 JSON in message.data.
const body = { message: { messageId: "136969346945", data: Buffer.from(JSON.stringify({"version":"1.0","packageName":"com.example.app","eventTimeMillis":"1790800914000","oneTimeProductNotification":{"version":"1.0","notificationType":1,"purchaseToken":"PURCHASE_TOKEN","sku":"coins_100"}})).toString("base64") } };

function decide(body) {
  const n = JSON.parse(Buffer.from(body.message.data, "base64").toString("utf8"));
  if (!(n.oneTimeProductNotification?.notificationType === 1)) return "ignore";
  return "verify, deliver once, acknowledge";
}

console.log(decide(body));
```

## How RevenueDot handles it

RevenueDot answers every handled message with 2xx and every temporary failure with 5xx so Pub/Sub redelivers it. For subscription types it re-reads the subscription from Google with `purchases.subscriptionsv2.get` and applies that state, and it acknowledges a new purchase if the app has not. A purchase RevenueDot has not seen is applied only when the app's **Track new purchases from server-to-server notifications** setting is on. RevenueDot fetches the product purchase for the `sku` and token, skips a purchase that is still pending, stores it under its order ID and acknowledges it. A new purchase gives `NON_RENEWING_PURCHASE`. The consumable flag comes from the product's type in your catalog.
