[Solved] IAP Google Store and PlayerIO

Hi

I'm using IN APP BILLING service to integrate with Google Store.

Process work fine and I receive the callback at

public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)

Now I use PlayerIO for my server and need set those parameters to be possible to registry the purchase with my server

info.Add("inapp_signed_data", args.purchasedProduct.receipt);
info.Add("inapp_signature","MY KEY FROM GOOGLE STORE");

after these be defined I call PlayerIO PayVaul to registry the purchase

_client.PayVault.UseBuyInfo("googleplayv2", info, successPayVault, failurePayVault);

but I'm receiving InvalidPurchageArguments: invalid "inapp_signature", does match "innap_signed_data"

I believe it is happen because the receipt provided by IAP is already parsed while PlayerIO is expecting the origninal encrypted data from Google Store

Can you help? Is there a way to get the Google Store data encrypted send to IAP?

 

@lauromrcruz Might you be able to confirm with PlayerIO that this is the cause? I will check with the IAP team here and see if they have insight also.

 

thanks a lot. I'm also trying to contact them.

 

Hi Jeff

I got this answer from PlayerIO
"In UseBuyInfo, you're supposed to pass two parameters, one is the INAPP_PURCHASE_DATA, and the other is the INAPP_DATA_SIGNATURE, both should be returned to your app when you've completed a purchase through Google Play."

Those are information that the google store send when the purchase happen.

I believe UNITY IN APP BILLING is parsing this and generate its own structure, the problem is I can't recognize where those information are.

Can you help me?

Thanks

 

Can you elaborate on your statement "after these be defined I call PlayerIO PayVaul to registry the purchase". Are you using the PlayerIO service just to track the transactions for reporting purposes? If you are using PlayerIO for handling the actual purchase, then you would want to ask them for specifics on integrating with Unity, perhaps ask for example code https://playerio.com/documentation/services/payvault/provider/googleplay .

 

Hi JeffD

Thank you for you reply.

What I'm trying to achieve is registry the purchase with our back end server.

On my application I decided to use the IN APP BILLING, that similar to use google Store API has a method called when a purchase happen.

the IN APP BILLING method has this signature

PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)

while google Store has this signature:

void onActivityResult(int requestCode, int resultCode, Intent data)

I believe the IN APP BILLING is passing the data provided by google and create the instance of PruchaseEventArgs.

Now to be possible to registry my purchase at a secure way with PlayerIO, it is required to use their PAYVAULT feature that expect receive in c# a dictionary with 2 information that are provided by the google store API

INAPP_PURCHASE_DATA
INAPP_DATA_SIGNATURE

Because the IN APP BILLING feature is receiving the call back from google store I believe is possible to access those information but I can't see them on the PruchaseEventArgs parameter received.

Is there a way to get those information?

Does make sense what I'm trying to achieve?

Thank you in advance

 

Sorry, I'm still not clear on "registry the purchase". So this is for reporting only, and not part of the transaction, correct? I met with the IAP team and they mentioned that you should be able to obtain this information from product.receipt. Please ask PlayerIO for sample code as they mention that they support Unity IAP.

 

Thanks a lot, I will try this.

 

Thank you all for your help, it did work.
