# Pre-assignment (PDF)

POST https://api.rebateright.com.au/AoBPreAssignment
Content-Type: application/json

This endpoint produces it: the pre-assignment Assignment of Benefit form as a PDF, one
signable page for each assignment.

Returns **`application/pdf`**: a printable Medicare bulk bill **pre-assignment** Assignment of
Benefit agreement: the form a patient signs to assign their Medicare benefit **before** the service.

For what pre-assignment is, when to use it instead of post-assignment, and the signing and retention
obligations, see the [Pre-assignment guide](/assignment-of-benefit/pre-assignment).

Supply the servicing provider, the `serviceStream`, and one or more `assignments`. Each renders as a
complete, signable page, so one request can produce a batch. Because a pre-assignment precedes the
claim, this request is **not** the bulk bill claim payload. This endpoint **renders** the document; it
does not lodge a claim or call Services Australia.

A pre-assignment cannot be used for Child Dental Benefits Schedule (CDBS) claims.

## How the form is chosen

You set the **service stream** explicitly with `serviceStream` (`general`, `pathology`, or
`diagnosticImaging`). It selects the assignor's statement and the date-column label for every page
of the request.

## Response

| Status | Content type      | Meaning                                                |
| ------ | ----------------- | ------------------------------------------------------ |
| `200`  | `application/pdf` | The rendered pre-assignment agreement.                 |
| `400`  | `text/plain`      | The request was malformed or missing a required field. |

Reference: https://docs.rebateright.com.au/api-reference/medicare-claiming/bulk-bill-claim/assignment-of-benefit/pre-assignment-pdf

## Authentication

- `x-api-key` header (required) — API Key authentication via header
- `x-minor-id` header (required) — Your Minor ID is three uppercase letters followed by five digits, such as `MDE00001`. Send the Minor ID exactly as issued. A malformed value gets a 400 with "The Minor ID is not valid." on every endpoint.

## Servers

- `https://api.rebateright.com.au` (Production, default)
- `https://test-api.rebateright.com.au` (Test)

## Request

### Body (application/json)

This endpoint expects an object.

- `serviceProviderName` (string, required) — The servicing provider's name, printed under **Details of the professional** alongside the provider number.
- `serviceStream` (enum, required) — The service stream. It selects the assignor's statement, the date-column label, and the description-column label printed on every page of this request. | Value | Statement (future tense) | Date column | Description column | |-------|--------------------------|-------------|--------------------| | `general` | …the health professional who will render the service(s). | Date of service | Basic service description | | `pathology` | …the approved pathology practitioner who will render the requested pathology service(s)… | Date of specimen collection | Description of service | | `diagnosticImaging` | …the diagnostic imaging provider who will render the requested diagnostic imaging service(s)… | Date of imaging procedure | Description of service | A specialist or allied-health attendance uses `general`. Pathology Group P9 (simple in-rooms tests) also uses `general`, the way Services Australia defines the streams.
  - Allowed values: `general`, `pathology`, `diagnosticImaging`
- `serviceProvider` (AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaServiceProvider, required)
- `assignments` (list of AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaAssignmentsItems, required) — One entry per patient. Each renders as a complete, signable agreement on its own page.

## Response

### 200

PDF bytes, a **Medicare online** bulk bill pre-assignment Assignment of Benefit agreement, carrying the minimum data set Services Australia requires.

- File download.

## Types

### AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaServiceProvider

- `providerNumber` (string, required) — The servicing provider's Medicare provider number, printed under **Details of the professional**.

### AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaAssignmentsItems

- `dateOfAssignment` (date, required) — The date the patient enters into the agreement. Printed as the **assignment date**.
- `patient` (AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaAssignmentsItemsPatient, required)
- `services` (list of AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaAssignmentsItemsServicesItems, required) — The services to be rendered under this assignment. Each prints as one row.
- `assignorIsPatient` (boolean, optional) — Whether the person assigning the benefit is the patient. Prints **Yes** or **No**. Omit it to print a **Yes / No** choice for completion by hand.

### AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaAssignmentsItemsPatient

- `givenName` (string, required) — The patient's given name. Printed as part of the patient (assignor) name.
- `familyName` (string, required) — The patient's family name.

### AoBPreAssignmentPostRequestBodyContentApplicationJsonSchemaAssignmentsItemsServicesItems

- `serviceDate` (date, required) — The expected service date, labelled date of service, specimen collection, or imaging procedure according to `serviceStream`.
- `description` (string, required) — Your plain-language description of the service to be rendered, the **basic service description**. Pre-assignment prints this in place of an MBS item number, because the exact item is often not known before the service. RebateRight prints it exactly as supplied; it is not validated against the MBS.
