Coupang WordPress Plugin Guide – How to Use the API for Affiliate Products and Monetization

Coupang is a leading South Korean e-commerce platform, often called the "Amazon of Korea." It sells everything from electronics to groceries and is famous for its Rocket Delivery service, offering same-day or next-day shipping.

It also runs Coupang Partners, an affiliate program where publishers can earn commissions by promoting Coupang products.

API Limitations

The Coupang API provides only basic product data such as product title, image, and price. It does not return extended details like product descriptions, attributes, or specifications.

👉 Important:

• You can search for products by keywords only. Searching directly by product URLs is not supported.

• Each request can return a maximum of 10 products.

• The API server may be restricted from many geo IPs, so it’s recommended to use local hosting servers for reliable access.

Even with these restrictions, the API is still a powerful way to add Coupang affiliate product blocks to your site and monetize traffic. You can also enhance listings by using the plugin’s built-in AI features to generate additional content.

Price Update Limitations

The Coupang API does not offer a direct method to check or update prices and stock status of products by product ID.

To keep product information current, the plugin uses the following fallback approach:

1. Re-search and try to match the product using the original keyword.

2. If no match is found, attempt to match by the product title.

This process usually finds the correct product and updates the price, but it is not 100% reliable. If a product cannot be matched, two outcomes are possible:

• Mark the product as out of stock, or

• Keep the last known price and mark stock status as unknown.

You can choose your preferred behavior in the module settings under the “Stock Status” option.

You can also set a keyword for auto-update to refresh product listings and keep them up to date.
