Newer Unity IAP has different TransactionID for Google Play

On version 1.23.1 and In App purchasing package version 2.0.6 when I make a purchase and receive the product, the transactionID from Google comes in the format like GPA.XXXX.

On the latest version this was changed to a much longer string of characters... Is this intentional?

Isn't GPA.XXX the desired format here?

 

Yes, there have been changes. I would encourage you to review the release notes for the last few versions. Google hasn't been consistent in this area so we've made changes to accommodate https://forum.unity.com/threads/uni...-core-package-2-2-1-are-now-available.415517/

 

What would be the best information to keep? The purchaseToken or the orderID?

I see Unity IAP now returns purchaseToken when we get transactionID.

However the users receive the order ID on the confirmation emails... When they contact us on support they don't have the purchaseToken, should we start saving both ids?

 

Can you elaborate, how are you "keeping" this data? I guess the answer would be "keep both".

 

Hey Jeff,

I'm having the same problem here.
This is causing issues with our backend receipt validation. Which property should we use now?

Thanks

 

Google changed the interface in the Google v3 Billing Library which we now use, the changes are mentioned here:

https://forum.unity.com/threads/uni...-are-now-available.415517/page-2#post-6506532

 

We keep the order ID because that's the info the users have regarding their purchases, when any issue happens and they contact us, that is the number they usually send.

We can only thank Google for using 2 IDs I guess?

They make us use purchaseToken for all validations and send the order ID to the users...

We will probably start saving both now, I'm "manually" extracting the order id from the receipt json.

 

I am looking into this.

 

Thanks @JeffDUnity3D , the order id is critical to handle customer support tickets when something isn't right. Was there any update on extracting the order ids when they are available in the newer Unity IAP versions?

 

I had asked the team previously, let me check on that. Agreed on your concerns.

 

The receipt JSON contains Payload which in turn contains orderId. This is the GPA version.

 

Thanks, I will manually extract for now it but ideally I'd love to have a convenient way to get it, like we had with the previous versions.

 

Yes, currently you'll need to extract the OrderID from the receipt. We plan to expose this as a product property in a future release

 

Any news about this?

 

No news, but you can certainly parse the receipt to get the value in the meantime.

 

Hi there.

I've updated the IAP plugin and now the TransactionID in receipt and the purchaseToken in Payload are the same.
How can I retrieve the TransactionID ?(GPA. ....)

 

From the receipt. In ProcessPurchase, it's in the passed argument as e.PurchasedProduct.receipt

 

Could you show some code example how to get the TransactionID from PurchasedProduct.receipt?

 

You first want to just inspect the receipt

Debug.Log("Receipt is " + e.PurchasedProduct.receipt.ToString());

Then you can use use string methods to parse the receipt https://docs.microsoft.com/en-us/dotnet/csharp/how-to/search-strings
