Hello,

We are working on a application/service which interacts with Okta via Okta Java SDK and OIDC/OAuth using Okta API scopes.

For the above to work, we have created Service application in Okta, using the Dynamic Client Registration API ([Dynamic Client Registration | Okta Developer](https://developer.okta.com/docs/reference/api/oauth-clients/))

Is there a Okta Java SDK API for Dynamic Client Registration, for registering new client and updating existing client ? I tried to search the okta java docs but I could not find any api for oidc client. The intention is, I think we can rotate the JWKS on oidc client based on some schedule.

Thanks

Have not checked if it’s exactly it, but it might be `Client.createApplication()` with application object configured according to [Apps | Okta Developer](https://developer.okta.com/docs/reference/api/apps/#add-oauth-2-0-client-application)

Yes you could use Client.createApplication() or DefaultOIDCApplicationBuilder to create OIDC client, I went with the later.
