 cryptographic libraries) and refresh tokens. Refresh tokens can only be introspected by the client that requested them.

+The introspection endpoint requires authentication. Since the request to the introspection endpoint is typically done by an API, which is not an OAuth client, the [`ApiResource`](/identityserver/fundamentals/resources/api-resources) is used to configure credentials:

+```csharp
+new ApiResource("resource1")
+{
+    Scopes = { "scope1", "scope2" }, // Replace "scope1", "scope2" with the actual scopes required for your API
+
+    ApiSecrets =
+    {
+        new Secret("secret".Sha256())
+    }
+}
+```
+Here the id used for authentication is the name of the `ApiResource`: "resource1" and the secret the configured secret. The introspection endpoint uses HTTP basic auth to communicate these credentials:
