Are there any quick ways to look up category IDs?

Currently there are three ways to confirm categories [displayCategoryCode]. 

1.  Use API that recommends categories 
This API recommends the Coupang category that most closely matches the product information that was entered (product name, etc). 
This is the fastest way to find product categories for bulk products. 

• Go to API recommending categories

2. Download Excel file 
WING > Product management > Product registration  > Product registration in bulk (Excel) > Upload Excel  > Click on [Download all category information]

• Koshi information: There may be multiple 'product koshi information categories' under a single category. Match by selecting one appropriate category.
• Purchase options: If mandatory, make sure to include under attributes for product creation 

3. API to query categories/lists 
Use API to query all categories on Coupang
