Frequently Asked Questions
- Why do Amazon FBA brands track Walmart.com pricing?
- Amazon's Competitive Price Threshold (CPT) algorithm monitors Walmart.com in real time. If an unauthorized 3P reseller discounts your SKU on Walmart, Amazon can strip your BuyBox even if you are the sole FBA seller—making automated `/v1/walmart/product` + `/v1/amazon/product` parity alerts essential.
- Can I pass a full walmart.com product URL instead of a numeric ID?
- Yes. `GET /v1/walmart/product` accepts either `?id=2659627283` or `?url=https://www.walmart.com/ip/2659627283`.
