I'm looking to use Roku In-app Payments to collection subscription payments from customers for my channel. It looks like I can use the Roku Channel Store Web Services API's "transaction-service.svc" call to validate a transaction (see http://sdkdocs.roku.com/display/sdkdoc/Web+Service+API). My channel sells monthly subscriptions. Consequently, the initial transaction could be valid, but next month the user could cancel his/her subscription, and/or the payment might fail. I would like to be able to make a Web service call from my Linux application server to verify that individual customer's subscriptions made vie Roku In-app Payments are still up-to-date/paid in full. Can I use the "transaction-service.svc" call to do that?

OK, I tried invoking the "validate-transaction" Web service and recieved the following response:

<result>
<errorCode i:nil="true"/>
<errorDetails i:nil="true"/>
<errorMessage>Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).</errorMessage>
<status>Failure</status>
<amount>0</amount>
<channelName i:nil="true"/>
<couponCode i:nil="true"/>
<currency i:nil="true"/>
<expirationDate i:nil="true"/>
<originalPurchaseDate>0001-01-01T00:00:00</originalPurchaseDate>
<partnerReferenceId i:nil="true"/>
<productId i:nil="true"/>
<productName i:nil="true"/>
<purchaseDate>0001-01-01T00:00:00</purchaseDate>
<quantity>0</quantity>
<rokuCustomerId i:nil="true"/>
<transactionId i:nil="true"/>
</result>

So, I would greatly appreciate if someone could verify that the following is true: If the actual currrent date is before the value of the "expirationDate" in the response from the validate-transaction service, then the customer has a valid/paid-up subscription. If a payment fails or the customer cancels, then the expirationDate element will be the last day of the last month that the customer has actually paid for a subsciption that he/she signed up for with the original in-app payment transaction.

Coudl someone let me know if the above statements are correct?

Thanks in advance for any help.
