{"id":"b2mmessaging-async-v1","name":"B2MMessagingAsync","description":"## Introduction\n The B2MMessagingAsync push-push API supports inbound submitMessages, submitMessageAcknowledgements, and getQueueMetaData endpoints and suits a high volume exchange of messages. \n Participants push their outgoing message to the e-Hub and the e-Hub pushes the message to the Participants Gateway. The message delivery occurs  asynchronously, where the initiator sends the message to the e-Hub and expects the outcome (such as MACKs, TACKs, or responses) in a different API call. The response, sent later, is sent to the Participants Gateway.","subscriptionRequired":false,"path":"NEMRetail/B2MMessagingAsync","protocols":["https"],"tagDescriptions":[],"authenticationSettings":{"oAuth2AuthenticationSettings":[],"openidAuthenticationSettings":[],"subscriptionKeyRequired":true},"subscriptionKeyParameterNames":{"header":"Ocp-Apim-Subscription-Key","query":"subscription-key","bearer":null},"apiVersion":"v1","apiVersionSetId":"5ms-b2mmAsync-v1"}
