How to match products when Rakuten's API hides the barcode
A developer built a tiered system to cross-match products across Rakuten and Yahoo Shopping APIs when Rakuten doesn't expose the JAN barcode. The approach uses a scoring function that checks if the JAN string appears in the product name or caption, with thresholds for confirmed matches (score ≥0.8), needs-review (≥0.5), and discard. This enables price comparison without relying on a structured JAN field from Rakuten.

A practical workaround for a common API asymmetry, but the manual scoring thresholds may not scale across thousands of products without tuning.
