Authorization Servers
Authorization Servers generate OAuth 2.0 and OpenID Connect tokens, including access tokens and ID tokens. The Okta Management API gives you the ability to configure and manage Authorization Servers and the security policies that are attached to them.
Work with the Default Authorization Server
Okta provides a pre-configured Custom Authorization Server with the name default. This Default Authorization Server includes a basic access policy and rule, which you can edit to control access. It allows you to specify default instead of the authorizationServerId in requests to it:
https://${yourOktaDomain}/api/v1/authorizationServers/default
vs
https://${yourOktaDomain}/api/v1/authorizationServers/${authorizationServerId} for other Custom Authorization Servers
