If you’ve enabled purchase verification, you can use the Adjust SDK to request purchase verification. There are two ways to verify purchases with the Adjust SDK:
- Create an
AdjustEventobject that represents your purchase and configure purchase properties for the target store. - Create an
AdjustAppStorePurchase(Apple App Store) orAdjustPlayStorePurchase(Google Play Store) object representing the purchase.
If you use revenue events to measure your purchases in Adjust, you should use the AdjustEvent class. If you only want to verify a purchase but don’t want to associate it with an event, use the AdjustAppStorePurchase or AdjustPlayStorePurchase class.
When you send purchase information with the Adjust SDK, Adjust does the following:
- Sends the information to the relevant store and waits for a status response.
- Forwards the status response to the Adjust SDK.
You can access the purchase verification status by using a callback. Results are returned as AdjustPurchaseVerificationResult objects containing the following properties:
verificationStatus(String): The status of the purchase.code(num): The status code of the purchase.message(String): Any message returned by the store.
Verify purchase and record event
static Future<AdjustPurchaseVerificationResult?> verifyAndTrackAppStorePurchase( AdjustEvent event) asyncTo send a revenue event for verification and listen for the purchase verification status, follow these steps:
- Instantiate an
AdjustEventobject with the your event token and set the following parameters:productId(String): The product identifier of the item that was successfully purchased.transactionId(String): The ID of the transaction you want to verify.
- Call the
Adjust.VerifyAndTrackPlayStorePurchasemethod with the following argument:event(AdjustEvent): Your instantiated event object. Expect the verification response to arrive as part of theFuture<AdjustPurchaseVerificationResult?>return value.
In this example, the purchase verification response is output to the logging daemon.
AdjustEvent adjustEvent = new AdjustEvent('abc123');adjustEvent.setRevenue(6.66, 'CAD');adjustEvent.transactionId = 'transaction-id';adjustEvent.productId = 'product-id';Adjust.verifyAndTrackAppStorePurchase(adjustEvent).then((result) { print('Verification status = $result?.verificationStatus'); print('Code = $result?.code.toString()'); print('Message = $result?.message');}static Future<AdjustPurchaseVerificationResult?> verifyAndTrackPlayStorePurchase( AdjustEvent event) asyncTo send a revenue event for verification and listen for the purchase verification status, follow these steps:
- Instantiate an

- Call the
Adjust.verifyAndTrackPlayStorePurchasemethod with the following argument:adjustEvent(AdjustEvent): Your instantiated event object. Expect the verification response to arrive as part of theFuture<AdjustPurchaseVerificationResult?>return value.
In this example, the purchase verification response is output to the logging daemon.

- Instantiate an

- Call the
Adjust.verifyAppStorePurchasemethod with the following argument:purchase(AdjustAppStorePurchase): Your instantiated event object. Expect the verification response to arrive as part of theFuture<AdjustPurchaseVerificationResult?>return value.
In this example, the purchase verification response is output to the logging daemon.
