  title: B2 M Messaging Async API
  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."
