billing

Webhook signature verification confirms that incoming Stripe events are authentic by validating a cryptographic signature included in each request. This prevents malicious actors from forging fake payment events. The Skill implements signature validation using Stripe's provided signing secret and verification methods to ensure only legitimate Stripe webhooks trigger billing logic.

Stripe webhooks can be retried if delivery fails, meaning the same event may arrive multiple times. Idempotent processing uses Stripe event IDs to detect and skip duplicate events, preventing accidental duplicate charges. This ensures your billing system processes each payment exactly once regardless of how many times the webhook is received.

Out-of-order events occur when webhooks arrive in a different sequence than they were sent, potentially causing state inconsistencies. This Skill handles out-of-order delivery by reconciling your server state with Stripe's source-of-truth data, ensuring your billing records stay accurate even when events arrive out of sequence.

Yes, Stripe webhooks support both subscription and one-time charge workflows. This Skill provides a unified webhook integration that orchestrates secure, reliable billing for both payment types, validating signatures and ensuring idempotent processing across subscription renewals and individual transactions.

Secure Stripe integration requires webhook signature verification, idempotent event handling, and reconciliation with Stripe's server truth to prevent duplicate or lost charges. This Skill provides a complete blueprint combining all three mechanisms to create a resilient billing orchestration that maintains financial accuracy across subscriptions and one-time payments.
