AppID will expire by the end of June. Should I stop using Shopping APIs and start using RESTful APIs like Buy APIs?
Hi @schmidtheim, No you don't need to stop using Shopping API neither App ID gets expired. Note:- Starting on July 1, 2021, developers using Shopping API calls must authenticate with an OAuth application access token using the X-EBAY-API-IAF-TOKEN HTTP header, as both the appid query parameter and X-EBAY-API-APP-ID HTTP header will be deprecated on June 30, 2021. Developers should start making plans at their earliest convenience to migrate to using OAuth application access tokens with https://api.ebay.com/oauth/api_scope scope. See the The client credentials grant flow topic for more information on generating and managing OAuth application access tokens. See the Specifying OAuth scopes topic for more information on OAuth scopes.
Currently, to use a Shopping API call, developers can either pass in their developer account App ID through either the appid URL parameter or through the X-EBAY-API-APP-ID HTTP header, or they can use an OAuth application access token that is passed into the X-EBAY-API-IAF-TOKEN HTTP header. Best Regards eBay Developer Program
