Hi @Anonymous  @blanca23_32,

Commerce API subscription calls like createSubscription support both Application and User access token created authorization code grant flow or client credentials grant flow.

An OAuth token created with the client credentials grant flow and the https://api.ebay.com/oauth/api_scope scope is required in order to create, update, or retrieve application-based subscriptions to notification topics.

An OAuth token created with the authorization code grant flow and the https://api.ebay.com/oauth/api_scope/commerce.notification.subscription scope is required in order to create, update, or retrieve user-based subscriptions to notification topics.

Thanks for the help,

Now I understand that to subscribe to an application-scoped notification, we need an application token, and to a user-scoped notification, we need an access token.

We want to subscribe to ITEM_AVAILABILITY but can't get it to work, tried both, user and application tokens.

According to the response from https://developer.ebay.com/api-docs/commerce/notification/resources/topic/methods/getTopics we need an application token which we have. The response also contains the following:

authorizationScopes: ['https://api.ebay.com/oauth/api_scope/buy.item.stream']

 But when I add this scope to the token request, I'm getting "The requested scope is invalid, unknown, malformed, or exceeds the scope granted to the client" as a response. With just 

https://api.ebay.com/oauth/api_scope the error is the same as the thread starter's (195011).

Any suggestions? Thanks!
