AEMO B2MMessagingAsync
The B2MMessagingAsync push-push API supports inbound submitMessages, submitMessageAcknowledgements, and getQueueMetaData endpoints and suits a high volume exchange of messages. Participants push their outgoing message to the e-Hub and the e-Hub pushes the message to the Participants Gateway. AEMO's public API catalogue lists 3 operation(s) for this API, gateway-routed under the path prefix /NEMRetail/B2MMessagingAsync. 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 3 operation(s) in the OpenAPI captured here were harvested from AEMO's developer-portal operations endpoints (https://dev.aemo.com.au/developer/apis/b2mmessaging-async-v1/operations?api-version=2022-04-01-preview), complete with parameters, headers, response codes and response examples.
