[Amazon App Store] Subscription Support

Does anyone have any pointers on best practices of implementing Subscriptions through Amazon App Store?

From my early tests, I noticed that it's possible to purchase a subscription, but I don't know the proper way (if there is any) to:

• Validate Receipts (I suppose it will be possible to parse the receipt obtained from Unity IAP callback and then validate remotely using this method);
• Get Subscription metadata before purchasing (trial period, billing period, etc);

Everything else seems to work just fine.

 

@JeffDUnity3D Is it possible to get the raw product data in a JSON format or something like that?

It would be nice to have this feature to create in-house implementations of store-specific stuff.

 

Another Amazon-related issue: the field "IsSandbox" is not populated correctly on the Unity receipt.
I have not yet tested if this happens on other platforms as well.

Check the full Unity Receipt below, note that "isSandbox" is true on the Amazon App Store receipt.

Code (none):

Any news on that topic? Are subscription on amazon supported within Unity IAP?
