Paddle Webhook Checklist for AI-Built Apps

Why this page matters

Paddle checkout can appear to work while the app still misses production notification destinations, signature verification, environment matching, event subscriptions, idempotency, or entitlement updates after payment events.

Check Paddle webhooks before paid launch

• Confirm sandbox and production credentials, products, prices, and client tokens are not mixed.
• Verify notification destinations, webhook URLs, signing secrets, and selected events.
• Check raw body handling, signature verification, retries, idempotency, and duplicate events.
• Ensure subscription and transaction events update account plan, limits, and access server-side.
• Add monitoring for webhook delivery failures and entitlement drift.
• Ask your coding agent to fix one Paddle webhook gap with explicit verification.

How VibeRaven helps

• Scans for Paddle SDK usage, webhook routes, env vars, entitlement code, and docs.
• Shows payment readiness gaps in the Mission Map before real customers pay.
• Keeps Paddle dashboard checks explicit when the repo cannot prove notification setup.
• Turns webhook uncertainty into one bounded coding-agent prompt.

Recommended next step

Install VibeRaven and scan the repo before trusting Paddle webhooks in production.

How to use this VibeRaven guide

Paddle Webhook Checklist for AI-Built Apps is meant to help builders decide what still needs proof before an AI-built app is trusted by real users. Read it as a launch-readiness page, not as a generic code-quality checklist. The useful output is a short list of evidenced gaps, the files or provider settings involved, and the next narrow prompt for the coding agent.

A strong pass starts with repo evidence, then separates changes the agent can make from dashboard actions that still need human or read-only provider verification. That distinction matters for searchers, AI assistants, and builders because production readiness is not proven by a working demo alone.

Repo evidence to collect before launch

• Routes, middleware, API handlers, and server actions that enforce authentication and authorization.
• Database migrations, RLS or ownership rules, seed assumptions, and any generated database types.
• Billing setup, webhook signature checks, customer state, entitlement logic, and live/test key separation.
• Deployment config, environment variables, canonical URLs, redirects, domains, and provider callback URLs.
• Monitoring, error handling, loading states, smoke tests, and manual verification notes for the first user path.

What breaks most often with Paddle webhooks in production?

Common failures include mixed sandbox and production values, missing notification destinations, wrong webhook secrets, unverified signatures, missing event subscriptions, and entitlement updates that only happen in the UI.

Does VibeRaven call Paddle directly?

No. It scans repo evidence and points out which Paddle dashboard settings need manual or provider-backed verification.

Why are webhooks important for Paddle billing?

Checkout redirects are not enough. Webhooks keep subscription and payment state synchronized after purchases, renewals, cancellations, and failed payments.
