A workaround stopped checking who sent payment updates

Receiving a message does not establish who sent it

A webhook is a machine-to-machine notification delivered to a receiving address in the integration. Stripe's event documentation says to verify that an event originates from Stripe before acting on it. It warns that unverified messages could trigger fulfillment, access changes or other record changes. This describes a possible consequence of the missing control; it does not establish that anyone attacked your store.

Stripe signature verification uses the original request body, the signature header and the receiving endpoint's signing secret. The original body matters because changing it can cause verification to fail. A workaround that accepts messages without the check can hide that underlying failure while leaving the integration unable to establish the message's origin. A familiar event name or recognizable order reference inside the message does not substitute for verification.

Find the changed control and the actions behind it

Ask the implementer for the deployed change record, the first known time the bypass was active and the receiving destination it affects. Record whether verification was removed, a failed result was ignored or the control's behavior is still unknown. A comment that verification was restored is not enough if it describes a file that was never deployed. Keep the installed integration and version attached to the finding.

Next identify what the handler actually does after accepting a message: changing payment-related order fields, handing an order to fulfillment, updating another system or queuing later work. Include only actions present in your integration. The point is to determine which records require comparison, not to infer that every incoming event caused every possible action.

Stripe documents that a 2xx response acknowledges delivery to the endpoint. Downstream work can occur later. A green delivery result therefore cannot establish that verification ran, that an order was handled correctly or that the business action finished. Keep delivery, verification and order processing as separate observations.

Reconcile the affected period using independent provider records

Use existing logs and order history to identify the actions taken while the bypass was active. In your authorized private records, connect each affected action to its claimed event reference and the matching event or payment found directly in the provider account. Record account context as well as the reference. An identifier copied from the incoming message is a starting point for lookup, not independent confirmation that the message was genuine.

Keep three outcomes distinct: the provider record supports the action, the provider record conflicts with the action, or the available records do not permit a conclusion. If records are missing, document the unreviewed interval and affected workflow rather than declaring it clear. Do not treat an order label created during the bypass as independent evidence of payment.

Stripe can deliver events more than once and out of generation order. Repeated or older messages alone do not establish tampering. They do mean the comparison must account for what the store already did. A manual resend also does not cancel automatic retries, so bulk replay is not a shortcut for reconciling the period. Any order correction or recovery action needs its own authorization and the actual current payment record.

Close the repair and historical reconciliation separately

Give the authorized implementer a specific repair question: which documented authenticity controls apply to this provider and integration, which one failed and what deployed change restores it before order actions occur? For Stripe, the review must account for the raw request body and the appropriate endpoint signing secret. Document where the check runs and how a failed check prevents the order action. Keep secret values out of the handoff.

The repair record should identify the deployed version, restoration time and evidence that the documented checks are in effect. Separately retain the list of earlier actions reconciled and those still unresolved. Restoring verification can address future handling; it cannot retroactively establish the origin of messages previously accepted without it.

For a Prism checkout consultation, summarize the platform, the bypass, the affected workflow and the remaining evidence gap. Confirm investigation and implementation responsibilities, scope, fees and terms before work begins. Do not send raw webhook bodies, customer records or secrets through the public form. This consultation does not establish the provider's approval of the research-only business.

Notification trust-boundary record

Use the last column to record findings from the deployed integration and existing real events. Keep full references in authorized internal systems and use private record pointers here. Close the control repair and the review of past actions as separate items; unknown coverage remains open.

Worksheet entries are not submitted by Prism’s worksheet and are not saved by the site. Use record types, availability, anonymized observations, or match/mismatch results. Do not enter government identifiers, customer names or addresses, customer messages, receipt-access links, card or bank details, passwords, or keys. Send sensitive documents only through the provider’s verified secure channel.

These are temporary notes. Leaving or reloading this page may clear them. Worksheet entries are not sent automatically. If you copy notes into the consultation message and submit the form, Prism receives them as part of your request.
