Hi @amsut-8924.

Catalog API call requires an access token created with the authorization code grant flow, using one or more scopes from the following list (please check your Application Keys page for a list of OAuth scopes available to your application):

https://api.ebay.com/oauth/api_scope/sell.inventory 

https://api.ebay.com/oauth/api_scope/commerce.catalog.readonly

See OAuth access tokens for more information.

Note: Only the sell.inventory scope is required for selling applications, and only the commerce.catalog.readonly scope is required for buying applications.
