Cleeng and Amazon Fire TV
Amazon Fire TV integration allows reducing complexity for the broadcaster. Cleeng will handle the receipt validation on behalf of the broadcaster.
After the receipt is validated Cleeng will create a subscription and manage the entitlement. It makes it easy for the broadcaster to allow users access to the content across different platforms when the subscription is bought through the app store. All you need to do is use the standard APIs for the entitlement validation `getAccessStatus()` or `getAccessibleTags()`.
When the subscription is canceled in the app store Cleeng will sync the entitlements accordingly. Subscription and transaction data will be available in the Cleeng dashboard reporting and analytics.
