Scan one page, one variant, and one optional feed row.
Merchant Match Preflight is a Chrome extension for checking a selected Shopify or WooCommerce product variant against supported visible fields, product structured data, and one optional local feed row.
Run a scan
- Open a supported Shopify or WooCommerce product detail page.
- Select the exact product variant you want to check.
- Click the extension icon to open its side panel.
- Optionally paste or import one redacted CSV, TSV, or JSON feed row for that same variant.
- Select “Scan current page.”
- Review the findings, make the correction, and scan again.
Supported boundary
Version 0.1.7 supports standard Shopify and WooCommerce Storefront/classic product selectors. Supported checks cover price, sale price, currency, availability, title, brand, SKU, GTIN, MPN, and selected variant conditions. Ambiguous, unsupported, and low-confidence pages return a non-pass state rather than a clean result.
What results mean
Findings identify deterministic inconsistencies among the available page layers. A clean scan applies only to the fields extracted within the supported boundary. It does not guarantee Merchant Center approval, inspect account state, or diagnose a suspension.
Optional usage measurement
The extension works without measurement. Measurement is off by default and starts only after you enable the setting and approve Chrome's optional permission for https://metrics.viaprime.com/*. When enabled, only a random pseudonymous installation ID, event metadata, and coarse enumerated buckets are sent. Page URLs, domains, product data, feed contents, prices, free text, and customer identities are not sent.
Turn the measurement setting off to stop transmission, delete the local measurement ID and queued events, and remove the optional collector permission. Measurement failures never block a scan.
Local history, export, and deletion
Compact scan evidence is stored locally for up to 30 days and capped at 50 records. You can export the current report or local evidence. Use “Clear all local data” to delete local history, settings, consent state, measurement identity, and queued events. Removing the extension also clears its local storage.
Reviewer verification
The stable fictional fixture and its sample feed require no account, credentials, payment, or customer data.
Beta access and contact
To join the private beta, request beta access. For support, privacy, or security reports, email publisher@viaprime.com. Do not send credentials, private account exports, customer personal data, or confidential client material.
Manual validation archive
The former website case-submission workflow is closed. Existing manual cases, aggregate evidence, and recheck controls remain available in the manual validation archive. They are separate from extension usage evidence.
