Use this as a working checklist, not a polished report. Open the page, flow, or system you want to review, go through each section, and write down what is broken, unclear, slow, missing, or hard for a customer to complete. If a check does not apply to your situation, skip it. The point is to find the few issues that would make the biggest difference before you spend time or money on Secure Online Payments.
Start with the sections closest to revenue or lead flow. If something is broken, unclear, or untracked, write it down before jumping into a rebuild.
Delivery
Before changing application logic, confirm that events are being delivered to the correct environment.
Check the webhook endpoint URL in Stripe.
Confirm live and test mode endpoints are not mixed.
Review recent delivery attempts and HTTP responses.
Check server logs for matching timestamps.
Confirm the endpoint is not blocked by middleware or redirects.
Event Handling
A delivered webhook still needs correct logic, duplicate protection, and useful logging.
Verify webhook signature handling.
Handle the specific events your flow depends on.
Use idempotency or duplicate protection.
Store useful payment and subscription identifiers.
Log failures with enough detail to debug later.
Payment problems should not be guessed through. If customers are charged but access is wrong, webhooks are failing, renewals are out of sync, or checkout errors are affecting revenue, get technical help before more transactions pile up.
Successful payments are not updating orders, accounts, or subscriptions.
Customers are charged but cannot access what they paid for.
Webhook errors, duplicate events, or failed renewals are showing up.
Staff are manually correcting payment status too often.
This resource is written for people who need practical checks, not a long theory document. It should help you decide what to fix, what to ignore, and what needs a deeper review.
