Prove whether Shopify product data still depends on Content API.

Identify whether Shopify, a Google app, a private app, an agency, or a custom service owns product uploads.

Ask each vendor whether they still use Content API for Shopping or Merchant API v1beta and request Merchant API v1 evidence.

Review Shopify IDs, offer IDs, feed labels, Merchant API resource names, ads, reviews, and dynamic remarketing dependencies.

Use no-upload discovery when source is unavailable, then scan authorized snippets or focused folders when available.

Record missing vendor answers as NOT_VERIFIED rather than treating generic readiness promises as proof.
