MLLP
MLLP Trigger – Receive HL7 Messages in WeHub
Summary (SEO Meta Description):
The MLLP Trigger in WeHub starts workflows when HL7 v2 messages are received over TCP/IP (MLLP).
Configure it to ingest healthcare data streams and control ACK validation.
Overview
The MLLP Trigger is designed for healthcare workflows.
It listens for incoming HL7 v2 messages over TCP/IP using the Minimal Lower Layer Protocol (MLLP) and starts a workflow whenever a message arrives.
This trigger is ideal for hospitals, labs, and healthcare systems that exchange HL7 messages in real time.
⚙️ Configuration Options
| Field | Type | Description |
|---|---|---|
| Label | String | Custom name for the trigger node. |
| Select Connection | Connection | Choose or create a TCP/IP connection for MLLP. |
| Period Alive | Integer | Duration (in seconds) to keep the connection alive. |
| Ack Validation | Enum | Determines how ACK is returned: ByMessageArrival or ByWorkflowSuccess. |
💡 Example Use Cases
- Hospital Systems → Ingest ADT (Admission, Discharge, Transfer) HL7 v2 messages in real time.
- Laboratories → Receive HL7 ORU messages with test results and process them into FHIR resources.
- Integration Engines → Connect legacy HL7 feeds into modern cloud-based applications.
- Clinical Workflows → Trigger alerts, notifications, or downstream processing upon receiving critical HL7 events.
FAQ
Q: What’s the difference between ByMessageArrival and ByWorkflowSuccess?
A:
- ByMessageArrival → Faster, acknowledges immediately (less reliable if workflow fails).
- ByWorkflowSuccess → Slower, but ensures the workflow processed the message successfully before ACK is sent.
Q: Does the MLLP Trigger support HL7 ACK customization?
A: Yes. The ACK can be customized downstream to include workflow status or error details.
Q: Can this trigger be used outside healthcare?
A: It’s possible, but MLLP is almost exclusively used in healthcare for HL7 v2 message exchange.
