Get sku for creating a listing on amazon with sp-api

Question

Client provided me following requirements for amazon selling partner API.

1. Search product by UPC /Asin.
2. Add Product listing. From Which API, I can get sku, as getCatalogItem api does not return any sku?

For product search, I am using following API. getCatalogItem https://sellingpartnerapi-na.amazon.com/catalog/2022-04-01/items?marketplaceIds=ATVPDKIKX0DER&identifiers=025725433841&identifiersType=UPC&includedData=identifiers,summaries,attributes,images,productTypes,salesRanks&locale=en_US

For listing product, I am using PUT /listings/2021-08-01/items/{sellerId}/{sku}.

From Which API, I can get sku, as getCatalogItem api does not return any sku?

Answer 1

What I know is that you will create the SKU value yourself.
