I am developing an application with in-app subscriptions. On our servers, I check the validity of each subscription through the Google Play Developer API.
As stated in the docs, a request to the Purchases.subscriptions endpoint, returns something like that:
{
"kind": "androidpublisher#subscriptionPurchase",
"startTimeMillis": long,
"expiryTimeMillis": long,
"autoRenewing": boolean
}
However, I am finding some strange behavior with it. When a user cancels a subscription through Google Play app, the "startTimeMillis" field is updated to the time of cancellation.
According to the documentation, "startTimeMillis" is "Time at which the subscription was granted", so I expected that this value should not change. Could anybody explain me why it is updated after a cancellation?
I have another important question that I can not test yet... Could someone, who has spent several months working with subscriptions, tell me if this "startTimeMillis" is updated too when the subscription is automatically renewed? I expect too that this should not change but... now, I am not sure about this.
Thank you
Had similar issue and found that:
When user cancels the subscription,
startTimeMillis
won't be changed, only autoRenewing changed to falseIf the user subscribes again after the cancelation, google will send you a new subscription token, but when querying with the previous token, the response would be changed to the same as the new token, i.e.
startTimeMillis
would be changed
