Hi @ravikiran-sattigeri,

All applications can be retrieved via this API -

https://fusionauth.io/docs/v1/tech/apis/applications/#retrieve-an-application

The roles should be attached to the returned object under a roles array.

If you could provide some additional context around what you are attempting to accomplish, we may be able to provide additional feedback.

If you have a support contract, please file a ticket via your Zendesk or Slack channels for additional questions. Thanks!

Thanks,
Josh
