AEMO HubMessageManagementV2
The HubMessageManagement push API retrieves the current list of B2B and B2M stop files. Business transactions are sent as aseXML documents carried as payloads inside the API message and transmitted over HTTPS. Participants can also use this API to: 1. Ensure technical requirements required to connect to the e-Hub are validated (for example, appropriate network ports are open). 2. AEMO's public API catalogue lists 1 operation(s) for this API, gateway-routed under the path prefix /HubMessageManagement. AEMO's own openapi-link export for this API is a shell — it declares paths: {} with zero operations and names an internal host — so the 1 operation(s) in the OpenAPI captured here were harvested from AEMO's developer-portal operations endpoints (https://dev.aemo.com.au/developer/apis/hubmsgmgt-v2/operations?api-version=2022-04-01-preview), complete with parameters, headers, response codes and response examples.
