June 2026 monthly summary focusing on business value and technical achievements. - Feature delivered: Stripe Payment Data now includes an optional has_card_on_file flag to indicate whether an organization has a card on file. This enables accurate invoice generation and correct handling of auto-renewal disclosures in the invoicing workflow. - End-to-end wiring: Populated the has_card_on_file flag inside BillingDetailsService.get_stripe_payment_data from the local PaymentMethod mirror table, aligning with the legacy Subscription.has_card_on_file() check and reducing the need for a separate RPC. - Proto and bindings update: Updated getsentry/sentry-protos to support the new field and regenerated Rust bindings to ensure type-safe usage across services. - Reference and collaboration: This work references REVENG-155 and involved co-authors on the commit, ensuring cross-team alignment for platform billing and invoicing improvements. Overall impact: Improves invoicing accuracy, reduces incorrect auto-renewal messaging for invoiced customers, and lays groundwork for more reliable billing data in downstream platforms. Technologies/skills demonstrated: Protobufs/IDL changes, Rust bindings regeneration, service wiring (BillingDetailsService), data modelling, cross-repo collaboration.
