Hi @kkarunakaran, 

Revenue verification is currently only available for Google Play and iTunes, but enablement for this can be found within out Help Center here: https://help.amplitude.com/hc/en-us/articles/115003116888#h_aeb19851-3c7c-46dd-b9dd-f8004059114e

I highly recommend reading over this documentation to better understand how to capture revenue verification.

Let me know if you have any questions!

Thanks a lot for reply @jarren.patao.

This part of the documentation mentions about amazon store verification which made me wondering why it was not working. May be the below link is outdated? https://developers.amplitude.com/docs/tracking-revenue#amazon-store-revenue-verification

Ah yes, you’re absolutely correct @kkarunakaran! Sincere apologies for that as it appears we just need to update our documentation on the Help Center to also include this information and I had forgotten about this verification as this isn’t one that I use myself. 

You’ll need to copy your Amazon Developer Shared Secret into the Sources & Destinations section of your project and send the ‘purchase token’ as the ‘receipt’ and the ‘user_id’ as the ‘receiptSignature’ for your purchase transactions coming in from Amazon. This is in relation to the below example provided in the developer documentation:

String purchaseToken = purchaseResponse.getReceipt();
String userId = getUserIdResponse.getUserId();

Revenue revenue = new Revenue().setProductId("com.company.productId").setQuantity(1);
revenue.setPrice(3.99).setReceipt(purchaseToken, userId);

Amplitude.getInstance().logRevenueV2(revenue);

It looks like you currently have a support ticket open so we will consolidate communications to that ticket if possible.

@jarren.patao  I already configured the sources and destination with Amazon Developer Shared Secret 

And below is the screenshot when I trigger a revenue event with purchaseToken and userId.

Not sure what I'm missing here, is my $receipt and $receiptSignature format correct. 

Hi @kkarunakaran! Looks like we have an existing support ticket open with you regarding this issue. Please see our email response and we can continue our discussion there!
