LambogeniusAny HL7 interface to any endpoint
Most HL7 v2 systems, MEDITECH included, exchange messages over MLLP: a TCP connection, each message wrapped in start and end block characters, and an acknowledgement (ACK) back for every message. The systems around them increasingly speak HTTPS or a message broker: REST APIs, SOAP web services, Azure Service Bus, cloud platforms such as Salesforce. The HL7 Edge Gateway sits between them. Each route takes messages from a source and delivers them to a destination, in any combination, and the sender always gets an HL7 ACK.

Partner ───── HTTPS/SOAP ──▶ :8443/svc ─┘ └─▶ Salesforce Apex REST (OAuth2)| Feature | What you get |
|---|---|
| Sources and destinations | MLLP and MLLPS, HTTP or HTTPS with REST or SOAP, Azure Service Bus queues and topics, and HL7 files on SFTP servers, on either side of a route. Send into MEDITECH as easily as out of it. See Routes. |
| X12 EDI and CAQH CORE | Claims, remittances, eligibility and enrollment, checked and answered with 999 and TA1, and real-time and batch exchange with payers' CORE servers. See X12 EDI. |
| HL7 v2 to FHIR | ADT, results, orders and immunizations as FHIR R4 transaction Bundles, sent to Azure Health Data Services, Google Cloud, HAPI or any FHIR server. See HL7 v2 to FHIR. |
| Two delivery modes | Pass-through (ACK with the destination's answer) or store-and-forward (ACK once the message is stored, then deliver in order with retries), chosen per route. |
| Security | OAuth2 / OpenID Connect tokens or API keys for callers, IP allowlists, mutual TLS, and OAuth2 or Salesforce logins to destinations. See Security. |
| High availability | Several gateways share replicated queues in NATS JetStream, with at most one message per route in flight across the cluster, so order holds. |
| Admin console | Live route state, queues and dead letters, pause and retry, cluster nodes, and license status. |
| Duplicate suppression | A resend with the same MSH-10 within the dedup window is acknowledged but not delivered twice. |
The gateway is a single binary for Windows, Linux and macOS, and a Linux container image. It needs no runtime, and TLS doesn't depend on OpenSSL. Download it from lambogenius.com with a free account.
The gateway posts to any HTTPS endpoint, including a workflow's HTTP trigger. If you want the payload as JSON with the MSH fields already parsed, or need to send MLLP from a workflow, look at the HL7 MLLP Connector for Azure Logic Apps instead.
