Real-time developer notifications reference guide

This topic lists and describes the types of Real-time developer notifications that you can receive from Google Play.

Encoding

Each publish made to a Cloud Pub/Sub topic contains a single base64-encoded data field.

{
  "message": {
    "attributes": {
      "key": "value"
    },
    "data": "eyAidmVyc2lvbiI6IHN0cmluZywgInBhY2thZ2VOYW1lIjogc3RyaW5nLCAiZXZlbnRUaW1lTWlsbGlzIjogbG9uZywgIm9uZVRpbWVQcm9kdWN0Tm90aWZpY2F0aW9uIjogT25lVGltZVByb2R1Y3ROb3RpZmljYXRpb24sICJzdWJzY3JpcHRpb25Ob3RpZmljYXRpb24iOiBTdWJzY3JpcHRpb25Ob3RpZmljYXRpb24sICJ0ZXN0Tm90aWZpY2F0aW9uIjogVGVzdE5vdGlmaWNhdGlvbiB9",
    "messageId": "136969346945"
  },
  "subscription": "projects/myproject/subscriptions/mysubscription"
}

After you decode the base64-encoded data field, the DeveloperNotification contains the following fields:

{
  "version": string,
  "packageName": string,
  "eventTimeMillis": long,
  "oneTimeProductNotification": OneTimeProductNotification,
  "subscriptionNotification": SubscriptionNotification,
  "voidedPurchaseNotification": VoidedPurchaseNotification,
  "testNotification": TestNotification
}

These fields are described in the following table.

Property name Value Description
version string The version of this notification. Initially, this is "1.0". This version is distinct from other version fields.
packageName string The package name of the application that this notification relates to (for example, `com.some.thing`).
eventTimeMillis long The timestamp when the event occurred, in milliseconds since the Epoch.
subscriptionNotification SubscriptionNotification If this field is present, then this notification is related to a subscription, and this field contains additional information related to the subscription. Note that this field is mutually exclusive with oneTimeProductNotification, voidedPurchaseNotification, and testNotification.
oneTimeProductNotification OneTimeProductNotification If this field is present, then this notification is related to a one-time purchase, and this field contains additional information related to the purchase.

Description

purchaseToken

The token associated with the purchase that has been voided. This information is provided to the developer when a new purchase occurs.

orderId

The unique order ID associated with the transaction that has been voided. For one time purchases, this represents the only order ID generated for the purchase. For auto-renewing subscriptions, a new order ID is generated for each renewal transaction.

  • (2) REFUND_TYPE_QUANTITY_BASED_PARTIAL_REFUND - The purchase has been partially voided by a quantity-based partial refund, applicable only to multi-quantity purchases. A purchase can be partially voided multiple times.

Note when the remaining total quantity of a multi-quantity purchase is refunded, the refundType will be REFUND_TYPE_FULL_REFUND.

Example

Here's an example of a notification for a new voided purchase:

    "orderId":"GS.0000-0000-0000",
    "productType":1
    "refundType":1
  }
}

Consuming VoidedPurchaseNotification

When your RTDN client receives a VoidedPurchaseNotification, note the following information:

  • packageName: This identifies the app.
  • eventTimeMillis: This informs the developer of the time the change in status occurred.
  • purchaseToken: The token provided to the user's device when the product was purchased.
  • orderId: This identifies the order associated with the voided transaction.
  • productType: This tells you if the voided purchase was an in-app purchase or a subscription.
  • refundType: This tells you the type of refund that voided the purchase.

If all you need to do for entitlement adjustments is locate the right purchase and order, then you have all the information you need at this point. To learn how to get additional information about the voided purchase, check out the Google Play Voided Purchases API, which is a pull model that provides additional data for voided purchases between a given timestamp.

For partially voided multi-quantity purchases, the refundableQuantity field provided by purchases.products contains the remaining number of purchased products that have not been voided.

TestNotification

A TestNotification contains the following fields:

{
  "version": string
}
Property name Value Description

Here's an example of a test notification:
