Frequently Asked Questions
How do I find a Walmart item ID?
The item ID is the numeric part of any Walmart product URL. For example, in https://www.walmart.com/ip/Product-Name/17835006350, the item ID is 17835006350. You can also get item IDs from the search endpoint results.
Does the Walmart API return real-time prices?
Yes. Netrows uses Walmart's store-specific pricing system to return accurate real-time prices. Prices are tied to a specific store location (Secaucus, NJ by default) which ensures consistent and accurate pricing data.
Can I get Walmart product reviews via API?
The current Walmart endpoints return rating scores and review counts. Full review text extraction is not included in the current response. For review text, the Walmart Official API requires a seller account.
What is the best Walmart API for price monitoring?
Netrows is ideal for price monitoring — no seller account required, real-time pricing with was-price and savings amount, and the ability to combine Walmart data with Amazon and Etsy pricing in a single API.
