According to Documentation, we want to retrieve the customer's listing, viewed items, etc. For these purposes, we use the Marketing API. For using it we must generate "Client Token" according to "The authorization code grant flow" procedure with "
https://api.ebay.com/oauth/api_scope/buy.marketing" scope. This scope available in listing in control panel, but on this request with needed scope parameters /* URL redirects a user to the application's Grant Application Access page */
https://auth.sandbox.ebay.com/oauth2/authorize? client_id=<app-client-id-value>& redirect_uri=<app-RuName-value>& response_type=code& state=<custom-state-value>& scope=<scopeList> // a URL-encoded string of space-separated scopes I receive error=invalid_scope. How to fix it. Anybody had same issues?
