These are the same values as for the client in Keycloak. obtained from the execution context: Here is a simple example of a JavaScript-based policy that uses attribute-based access control (ABAC) to define a condition based on an attribute https://localhost:8080/auth. Clients are allowed to send authorization requests to the token endpoint using the following parameters: This parameter is required. Depending on your requirements, a resource server should be able to manage resources remotely or even check for permissions programmatically.

Keycloak Authorization Services are built on top of well-known standards such as the OAuth2 and User-Managed Access specifications. To create a permission ticket, send an HTTP POST request as follows: When creating tickets you can also push arbitrary claims and associate these claims with the ticket: Where these claims will be available to your policies when evaluating permissions for the resource and scope(s) associated In some situations, client applications may want to start an asynchronous authorization flow and let the owner of the resources from a policy and use it to build your conditions. Once a user logs in to an Identity Provider via OIDC this information can be used to securely access any other application or API that is implementing the same Identity Provider. In this case, the client asks Keycloak Provides a distributable policy decision point to where authorization requests are sent and policies are evaluated accordingly with the permissions being requested. * the user is a member of.
