## Setup Type

**Self-Service with Prerequisites** - You can obtain credentials yourself through Oracle's Code Console, but the clinic must first have an account. If they don't have an account, manual credential requests through Oracle are required.

## Required Credentials

To integrate with Cerner Millennium in production or using your own credentials in Leyr Sandbox, you'll need:

- Client ID
- Client Secret
