Use the browser for customer experience. Use verified server-side evidence for fulfilment decisions.
A return URL is a navigation event
A customer returning from a payment page tells you where the browser went. It does not, by itself, prove that the payment succeeded. Keep the return page useful: display the order reference and retrieve the latest known state from your backend. Avoid unlocking a paid service solely because a URL contains a success parameter.
A webhook carries a server-side update
A webhook is an HTTP notification sent to an endpoint in your application when an event occurs. Stripe’s webhook guidance illustrates why integrations should account for duplicate or out-of-order delivery. Those are useful design considerations, not a promise about ZytePe’s delivery schedule. Provider-specific signing, acknowledgement and retry behaviour must come from the actual integration contract.
Authenticate before changing business state
Follow the signature scheme agreed with your provider and verify the exact representation it specifies. ZytePe’s verification guide identifies canonicalisation and secret configuration as points to confirm before relying on callbacks. Do not assume that another provider’s raw-body example will work unchanged, or treat an unsigned event as verified just because its JSON looks plausible.
Make fulfilment repeat-safe
Store the payment reference and the state transition your application accepted. If the same confirmation arrives again, the business should not ship a second parcel or create another subscription. When updates conflict, inspect the documented status workflow and retain the evidence for investigation. Keep secrets and customer information out of application logs and support screenshots.
Keep a recovery path
A status endpoint helps investigate a known payment when a callback is missed or the customer asks for help. Use the provider’s documented query pattern and limits rather than continuous polling. For ZytePe, start with the hosted checkout, webhook verification and transaction-status guides, and agree on unresolved deployment details before going live.
