Add OAuth 2.0 scope to client in Keycloak

After performing the previous steps in Keycloak, an OAuth 2.0 scope and client is available. To get the scope after the OAuth 2.0 client authenticates against Keycloak, you need to assign the scope to the client.

Log on to Keycloak and go to clients and select oidclient. This is the client created earlier.

Go to tab “Client Scopes”

Assign the previously created scope to the client.


The scope is assigned to the client. Now the client can authenticate and Keycloak will issue the OIDC tokens and include the given scope.

Create OAuth 2.0 scope in Keycloak

OAuth uses scopes to restrict access to resources. “Scope is a mechanism in OAuth 2.0 to limit an application’s access to a user’s account. An application can request one or more scopes, this information is then presented to the user in the consent screen, and the access token issued to the application will be limited to the scopes granted.” [link]

A service is assigned to a scope, therefore without being allowed to access a scope, you cannot access the resource. You can create scopes independently from the resource, that is: first create a scope, then assign the scope to a service you want to access. In reality, you should first create the service and then assign a scope to it.

After knowing the scope, log in to Keycloak and create a client scope. Later this scope will be assigned to a client. If the client authenticates then in Keycloak, the scope is assigned to it and the client can access the service.

Click on create

In the following form, enter the data for the OAuth scope:

  • Name: Scope for service. Here I used ZDEMO_CDS_SALESORDERITEM_CDS_0001, a scope for a CDS Service. Don’t worry, it’s just an example, Gateway does not work with OpenId Connect.
  • Description: SAP Gateway OData service
  • Protocol: openid-connect
  • Display on Consent Screen: off


The OAuth scope is created. It can now be assigned to a client.


When you change the scope of the service, you need to update the scope information here too.
