- Once input, hit 'Send'. This will generate the Access token as shown in Figure 10.
- Select and copy this as indicated in Figure 9. Please note that your access token will only last an hour once it has been generated.
Using an access token to access the API
Open a new tab in Postman once more (Figure 5) and enter the request URL for the API. This can be obtained from the Developer Portal in the API tab. Refer to item 3 as shown in Figure 4 to locate the URL. Please note that you should exclude everything from ‘[‘ to ‘]’ at the end of the URL.
Within the Authorization tab, ensure the Type is set to Bearer Token and paste the access token copied from the Postman ‘Post’ page, as described in step Obtaining an Access token through Postman. The location of fields that need to be populated is shown in Figure 11.

What is the approach in the model for schedules and SoC?
The PBS APIs have been built in concert with a Physical Data Model that represents a de-normalised view of the PBS to assist with easier consumption of the data. Each endpoint represents one of the tables displayed on the data model.
A complete set of data is pushed into the API system when a new monthly Schedule is released. The Schedule API contains the records associated with all available data in the API system. The Schedule number appears on every endpoint and is used to link all relevant data records together.
The Summary of Changes endpoint contains the records relating to the events for specific pieces of data (i.e. endpoint/field) relating to any changes that have occurred between the current and previous schedules. For instance, if an Item’s Claimed_Price has been updated then a record will appear in the current Schedule’s data that shows the change and includes the actual SQL statement that can be applied to the previous Schedule’s data to create the current version of that field.
By applying all changes held in the Summary of Changes endpoint for the current schedule against the data from the previous schedule, a User can recreate the current schedule’s data.
The SQL statements contained in the Summary of Changes are produced in SQL Server syntax and can be applied to the data using the following process:
- Data for the previous Schedule is loaded into a database. (Can be achieved by downloading all endpoint data for the previous Schedule and uploading into an empty database)
- All values of the Schedule_Code are updated to reflect the current Schedule_Code.
- The SQL statements for the current Schedule can then be applied. (Though care must be taken to apply changes in the most logical sequence to ensure primary key/foreign key constraints are maintained.)
How does the design handles intra-release changes?
The cadence of release will follow the current XML data file release process, that is new files will be released on a monthly basis.
Where the need arises for an additional release of data, a new Schedule number will be created, and the API data will be refreshed with all relevant data for that Schedule, in much the same way as a normal release occurs currently.
The Summary of Changes endpoint will reflect the data changes between Schedules in the same way.
How are API versions / deprecations being supported?
Like any system, changes may be required to introduce new improvements or remedy a previous error. To ensure that users are not inconvenienced by sudden changes to the API endpoints, previous (or deprecated) versions of the API endpoints will still be available for a period following a new release of updated endpoints.
Access to the current and previous versions of the API endpoints will be controlled through changes to the of URLs of the endpoints themselves.
As an example, Version 1 of an endpoint may have the URL:
https://data-api.health.gov.au/pbs-embargo/api/VERSION1/<endpoint>
whereas Version 2 of that endpoint may be given the URL:
https://data-api.health.gov.au/pbs-embargo/api/VERSION2/<endpoint>
The URL names allocated to endpoints are specifically referenced on the relevant Swagger documentation page under the “Request” heading.
Can the API be downloaded as a JSON or CSV?
The PBS DDS API endpoints have been developed to enable data to be received in either JSON (JavaScript Object Notation) or CSV (Comma Separated Values) format.
This is achieved by using the “Accept” parameter in the API Get statement header. For JSON use Accept = “application/json” (this is the default); for CSV use Accept = “text/csv”.
In Postman, this is achieved by setting an “Accept” key in the Headers tab. Once the data has been received, the file can be downloaded and saved.
How can the API be filtered by PBS code and program?
The API endpoints have been created with ease of use in mind, and the amount of data that can be requested can be refined using a series of parameters specific to each endpoint.
These are documented on the Swagger page for each endpoint under the “Request Parameters” header.
Filtering of the data can be achieved by adjusting the “Get” statement to include the relevant parameter.
e.g. for the Items endpoint, requesting a specific Schedule would look similar to this:
https://data-api.health.gov.au/pbs-embargo/api/VERSION2/items?schedule_code=1234
Using a tool, such as Postman, this can be achieved by adding an entry to the Query Params list. The tool will then automatically add the parameter to the Get statement executed.
Can the API be implemented into Users systems?
To make the transition of receiving systems as simple as possible, the PBS DDS API system has been designed to effectively emulate the existing XML file download system as closely as possible.
The intended operation is for end Users to access the API endpoints and retrieve all data associated with a Schedule in one request and download that file to local storage ready for upload into their own systems/databases.
To ensure a higher level of stability of the API system, a limit of one request per second has been implemented. The system has not been designed as a high-volume real-time system, but rather as a data storage and retrieval system to enable software vendors and users the ability to download and store local copies of the data.
