fluent_cart/customer_portal/subscription_data

The fluent_cart/customer_portal/subscription_data filter changes subscription data returned in a FluentCart customer-portal detail view. It is intended for customizing the customer-facing representation, distinct from the admin subscription-view filter or a subscription-list query filter. Use it when adding presentation data for an authorized customer’s existing subscription. It does not itself grant permission to read another customer’s records or change the subscription’s billing state.
