billing-integration-safety

What problem does it solve?

Billing integrations frequently suffer from duplicate webhook deliveries, out-of-order events, and state drift between the billing provider and your database. This Skill provides a robust framework for secure webhook handling, idempotent processing, and auditable billing state.

Core Features & Use Cases

• Webhook signature verification and secure delivery to prevent tampered events.
• Idempotent event processing with deduplication to avoid double activations or charges.
• Atomic, auditable updates to local subscription state and an immutable billing audit trail.
• Grace-period and dunning workflow integration to manage failed payments without abrupt access loss.
• End-to-end reconciliation between provider state and local state, with periodic checks.

Quick Start

Configure a Stripe webhook endpoint that validates signatures and processes events idempotently in a transactional workflow.
