Prerequisites
To access the Network findById method, you need to establish an API user to access the NHVR Developer Platform. For a step by step guide see Logging into the Developer Platform.
Using the network findById API from the Network Service
The network findById API is exposed from the Network controller from the NHVR Portal - Network Service.
Every call to the network findById API should include the following headers:
Header | Value | Note |
Content-Type | 'application/json' | All calls are made using JSON data structures |
Ocp-Apim-Subscription-Key | Your subscription key for the NHVR Portal API | The subscription key uniquely identifies you to the NHVR Portal API |
The network/networks/{id} endpoint uses the GET method and passes in a mandatory path parameter id (networkId). Optional query parameters accessProductDocumentId and accessProductApplicationId can also be included in the endpoint.
https://api-public.nhvr.gov.au/network/networks/{id}Specification
The full network find API specification is available on the NHVR Developer Platform: NetworkController.findById.
