Use Cases and Practical Examples
1. Monitoring Seller Performance
Regularly monitoring seller performance is crucial. Use SellerMagnet’s Amazon Seller Review API to track feedback ratings and review counts over different time periods. This allows you to quickly identify underperforming partners and take corrective action.
Here’s an example request using the API:
curl --request GET \
--url 'https://sellermagnet-api.com/amazon-seller-review?sellerId=A1CWSGXIR635I6&marketplaceId=ATVPDKIKX0DER&api_key=YOUR_API_KEY'
Here is a example response:

}
This data can be used to create performance dashboards, set alerts for negative feedback trends, and identify sellers who consistently deliver excellent service.
2. Assessing Product Quality and Compliance
Product reviews often highlight quality issues or compliance concerns. For example, reviews might reveal that a product doesn’t match the description or that a seller is violating Amazon’s pricing policies. Use SellerMagnet’s API in conjunction with keyword analysis to flag these reviews and take appropriate action.
You can also use the Amazon Product Lookup API to access product details, review metrics, and other crucial information.
