Additional sizes and colors of a product create product variations that merchants can offer to customers to select from. Offering a product in multiple sizes and colors, therefore, provides customers with a better shopping experience. Similar to adding products, merchants can add sizes and colors to products manually, via CSV feed file, or via API.
Add sizes and colors manually
First, navigate to Merchant Dashboard Products > Add New Product page. Scroll down to the Variations (optional) section, select the checkbox, and type in the colors and sizes one at a time. (Note that Wish offers a selection of acceptable colors and acceptable sizes for merchants to input.)
Upon clicking Apply, all product variations with the provided color and size combination will appear below for merchants to input more details for each variation, such as image, SKU, price, inventory, etc.:
Add sizes and colors via CSV feed file
Merchants may consult this article for a comprehensive walkthrough of how to add products (including colors, sizes, and other product attributes) via CSV feed file.
Specifically, merchants may specify two column headers: Color and Size. Download an example CSV from the Merchant Dashboard Products > Add/Edit Products with CSV page if needed.
Add sizes and colors via API
Merchants can also add variations and specify colors/sizes via API. Check this API documentation for details.
