Shopify App Incident Report: A Working Template for Developers

Begin with the app name, internal incident reference, governance ticket reference and report version. Identify the report owner and the period the document covers. State why the report was prepared and which requests it addresses. Keep private contact details inside the controlled report rather than public filenames or email subjects. Record who may receive the document and how later revisions will be distributed.

Add a short executive summary that describes what is confirmed, the current operational state and the principal unknowns. Do not copy a vulnerability’s theoretical impact into the summary as if it were a verified incident outcome. A report might establish unauthorized requests but lack evidence about whether records were retrieved. That distinction belongs near the beginning, not hidden in an appendix that the reviewer may miss.

Create a chronological record with timestamp, timezone, event, source reference and confidence. Include detection, validation, containment, access changes, deployments and testing milestones. Where different logs use different timezones or clock settings, explain the conversion. Retain original timestamps in your evidence register. A normalized timeline is a working interpretation; it should remain traceable to the underlying records.

For an illustrative entry, write “2026-10-01 09:15 UTC: endpoint disabled by deployment D-17; deployment log E-08” only when those values come from your own evidence. Do not reuse that example as a real incident date. Separate the time an event occurred from the time it was discovered. If the event time is unknown, say so instead of choosing the first date mentioned in an email thread.

Describe the relevant app components, backend services, environments and data flows. Explain which merchant or role boundaries were examined and which remain unverified. Reference the version affected by the issue rather than implying every historical release had the same behavior. Record the basis for any impact statement: logs, reproduced access, stored artifacts, developer analysis or a third-party finding.

Use separate fields for confirmed exposure, possible exposure and evidence gaps. Absence of a log entry may reflect limited retention or incomplete instrumentation, not absence of activity. Avoid publishing merchant identifiers or customer records in an example report. Where legal notifications may apply, obtain qualified advice; a technical report does not determine every notification obligation or replace the channel specified in Shopify’s correspondence.

Explain the technical cause only to the extent it is established. A reproducible authorization defect might be confirmed even when the identity of an actor or the full incident history is not. Distinguish the vulnerable control from contributing factors such as missing monitoring, delayed escalation or incomplete tests. If alternative explanations remain possible, record them and identify the evidence needed to resolve them.

Containment entries should name the action, time, owner and intended effect. Examples include restricting an affected function or revoking compromised credentials, where justified by the situation. Do not present disabling a feature as proof that the underlying code is fixed. Include any evidence-preservation step taken before changes, and explain unavoidable gaps. Your report should allow a reader to understand both the response and its limitations.

For each finding or identified cause, assign an action reference, owner, status, implementation evidence and verification reference. Keep “planned,” “deployed” and “verified” as distinct states. A deployed patch can remain unverified until the original test condition is safely reproduced against the correct version. Where verification covers only selected roles or endpoints, describe those limits.

If independent VAPT is separately requested, link its report reference and agreed scope without treating it as a reconstruction of the incident. Incident investigation asks what happened based on available evidence. VAPT evaluates exploitable weaknesses during the assessment. Include retest results when available, but do not silently replace the original findings. A reviewer should be able to trace what changed and why the status changed.

Append an evidence index, affected-version summary and finding-to-action map rather than an uncontrolled dump of raw records. Keep original evidence in a restricted location and use redacted copies for routine review. Check that redaction removes tokens, credentials and unnecessary personal data from screenshots as well as text. Preserve enough context for the technical conclusion to remain understandable.

Before submission, have the technical owner check that every claim has evidence or is explicitly qualified. Check that the document answers each item in the notice and that report names match the cover note. Submit through the requested governance channel and keep a versioned copy of what was actually sent. Scantra can discuss scoped investigation and documentation support, but Shopify alone decides whether the response satisfies its review and whether an app is relisted.
