RebateRight issues it. Your first Minor ID comes with your account when you sign up, beside your API Key. It is MDE and 5 digits, such as MDE12345. For each further location, email hello@rebateright.com.au and we issue one. If you are setting up several clinics at once, tell us, and we issue a set in advance for you to assign as each one opens.
No PRODA setup. RebateRight sets up the Minor ID with Services Australia on your behalf. If the clinic claims or uses the AIR, each practitioner completes the HW027, and we send you RebateRight’s PRODA Organisation Registration Authority (RA) number, which the form asks for.
In the web app and the browser extension. Save your Minor ID and API Key once in Connection Settings, and they are sent with every check. The browser extension uses the same Minor ID and API Key.
In your own software. Each request carries the clinic’s Minor ID in the x-minor-id header, in test and in production. A vendor serving many clinics uses one API Key for all of them, and the Minor ID of the clinic each request is for. The API docs give the details.
