[BUG] New subscription (for google) need the v2 endpoint to verify them

[Hoegje]

Subscriptions can soon no longer be validated with the original subscription link, but should go to the v2 version.

https://developer.android.com/google/play/billing/compatibility

Description

I tried a long time to get things working with the current code, but google was giving me cryptic error message saying I provided wrong arguments to the API call when calling the URL:
Method: https://androidpublisher.googleapis.com/androidpublisher/v3/applications/{packageName}/purchases/subscriptions/{subscriptionId}/tokens/{token}

Expected Behavior

I would have expected it to say something about the subscription.

Actual Behavior

I always received : no matter what I tried
Error Response: { "error": { "code": 400, "message": "Your request is invalid for this subscription purchase.", "errors": [ { "message": "Your request is invalid for this subscription purchase.", "domain": "androidpublisher", "reason": "subscriptionInvalidArgument" } ] } }

Possible Fix

Looking at the following link, I noticed there is now a subscriptionv2 endpoint that should be used.
https://developer.android.com/google/play/billing/compatibility

Also present in the androidpublisher.v3.json file:
"subscriptionsv2": {
"methods": {
"get": {
"description": "Get metadata about a subscription",
"flatPath": "androidpublisher/v3/applications/{packageName}/purchases/subscriptionsv2/tokens/{token}",
"httpMethod": "GET",
"id": "androidpublisher.purchases.subscriptionsv2.get",
"parameterOrder": [
"packageName",
"token"
],
"parameters": {
"packageName": {
"description": "The package of the application for which this subscription was purchased (for example, 'com.some.thing').",
"location": "path",
"required": true,
"type": "string"
},
"token": {
"description": "Required. The token provided to the user's device when the subscription was purchased.",
"location": "path",
"required": true,
"type": "string"
}
},
"path": "androidpublisher/v3/applications/{packageName}/purchases/subscriptionsv2/tokens/{token}",
"response": {
"$ref": "SubscriptionPurchaseV2"
},
"scopes": [
"https://www.googleapis.com/auth/androidpublisher"
]
}
}
}

Steps to Reproduce

When using the new v2 framework in googleplay.py, it seems to work again:

    def check_purchase_subscription(self, purchase_token: str, product_sku: str, service) -> dict:
        try:
            purchases = service.purchases()
            subscriptions = purchases.subscriptionsv2()
            subscriptions_get = subscriptions.get(
                packageName=self.bundle_id,  token=purchase_token
            )
            result = subscriptions_get.execute(http=self.http)
            return result
        except HttpError as e:
            if e.resp.status == 400:
                raise GoogleError(e.resp.reason, repr(e))
            else:
                raise e
