We want to develop extensions that are billed entirely via IAP (comment from Shopware: IAP stands for In App Purchases) – without our own subscription logic or external billing. Typical use cases are usage-based features such as quotas (e.g., search volume per month), limits, or activations with periodic renewal.

Currently, Shopware.InAppPurchase.isActive(‘MyExtensionName’, ‘my-iap-identifier’) only returns a Boolean (purchased: true/false).
However, for usage-based models, we lack the specific billing period, e.g., to reliably reset quotas when transitioning to the new period.

Our request/feature request:
In addition to isActive(), minimal contract information would be helpful, e.g.:
- Purchase or start date of the current billing period
- Billing interval (e.g., monthly, annually)
- Flag indicating whether it is a wildcard/stage environment

This would allow usage-based features (such as search volume, API quotas, free requests, etc.) to be implemented correctly, transparently, and fairly— without having to implement a parallel subscription or billing solution alongside Shopware IAPs.
