When to use this Listener

The MLLP Listener implements the Minimal Lower Layer Protocol (MLLP), a standard for receiving and transmitting HL7 messages via TCP/IP.

The MLLP Listener is used to build Etlworks API, which receives a payload from third-party applications, using the MLLP protocol. Once the payload is received, the MLLP Listener sends back the acknowledgment and redirects the payload to the designated Flow. If the Flow is scheduled, it will be automatically executed each time the payload is received.

Read how to use MLLP Listener to receive and process HL7 messages over the MLLP protocol.

• Use default validation: if this option is selected, the default HL7 message validation will be performed.
• Use TLS/SSL: if this option is selected, the MLLP Listener assumes that the SSL protocol is used for receiving and transmitting HL7 messages.
• Encoding: message character encoding. If No Encoding is selected, the message will not be additionally re-encoded.
