How to Prepare a VAPT Report for a Shopify App

Extract the app identity, triggering issue, requested documents and deadlines. Tell the assessor whether Shopify asked specifically for independent testing or remediation verification. Provide the original notice through a safe channel, redacting information that is not needed for scope. Do not assume a generic website package covers your embedded app and backend.

Write down the desired deliverables: initial findings, a developer discussion, final report, retest addendum and incident documentation if requested. Confirm which are actually included in the agreed engagement. Establish how urgent findings will be communicated before a report is complete. An attractive certificate should not replace a report that explains the tested assets and results.

List your frontend, backend domains, API paths, workers, integrations, authentication flows and data stores. Show how the app associates requests with a merchant and which permissions each role receives. Describe install, uninstall, token issuance, webhook processing, exports and other sensitive workflows relevant to the app.

Identify production and test environments, deployed versions and material differences between them. Provide an authorized route to test realistic functionality without exposing unrelated merchant data. If production-only conditions matter, agree explicit safety limits. Testing permission should cover the app assets you control; third-party platforms and merchant stores require appropriate separate authorization.

Prepare multiple authorized test stores or tenants and accounts for relevant privilege levels. A single administrator account can hide the authorization risks that matter most in a multi-merchant app. Explain which actions may affect billing, emails, jobs or external systems so the tester can avoid unintended side effects.

Agree schedules, contacts, rate limits, stop conditions and handling of sensitive discoveries. Provide API documentation and examples without embedding live secrets into public forms. Keep an access log and revoke temporary credentials when work finishes. If a control cannot be tested because access is missing, expect that limitation to appear in the report rather than a claim of full coverage.

A useful finding identifies the affected asset, preconditions, safe reproduction sequence, observed result, severity, business impact and recommended fix. Evidence should demonstrate the issue without publishing customer records or reusable secrets. Developers should be able to reproduce it within authorized test conditions and understand what control needs changing.

Track each finding through a ticket, owner, change and deployment version. If the fix applies to sibling routes or jobs, record that coverage. Do not mark a finding closed only because a developer ticket is complete. Keep disagreement about severity or exploitability explicit and evidence-based, with the assessor’s conclusion clearly separated from the team’s risk decision.

Confirm that the final report contains dates, scope, methodology, coverage limitations, findings and a conclusion proportional to the work performed. Add retest results that show fixed, partially fixed and open statuses where verification was commissioned. Keep original findings distinguishable from later verification so the review history is not lost.

Coordinate the VAPT with any Incident Report through shared references and a cover note. Submit the requested documents through Shopify’s stated channel. Scantra can review the notice and discuss the preparation and testing scope; it does not promise that a particular format or report will produce relisting. The governance decision belongs to Shopify.

Before the agreed start, test that each provided account can reach the expected environment and that its role matches the scope. Confirm the authorized tenant data is synthetic and identify actions that trigger billing, emails or jobs. Record the deployed version and known production differences. Give the assessor a contact for access failures and urgent findings through a controlled channel. Do not include active credentials in the scope document, which may be forwarded to reviewers later. If a planned surface cannot be accessed, decide whether to restore access, change the schedule or record an explicit exclusion. That decision must be visible in the report. Readiness is about enabling representative testing safely, not giving unrestricted access to every connected merchant or platform.

Keep a separate access readiness owner so testing does not depend on informal messages between several developers. That owner should confirm the agreed roles and environments before start, record any missing access and coordinate safe credential expiry when the work is complete.
