Challenge
Channels sprawl into an unmaintainable mess
Agnotic approach
Consistent naming, shared code templates, and documented channel topology so the hundredth interface is as clean as the first.
Interface Engine
Mirth Connect / NextGen Connect integration
We design, build, and operate Mirth Connect (NextGen Connect) interface engines: channels, source and destination connectors, and transformers that move HL7 v2, FHIR, X12, and flat files reliably between systems.

What is Mirth Connect?
Mirth Connect is NextGen Healthcare's interface engine: it receives, filters, transforms and routes healthcare messages such as HL7 v2, FHIR, X12 and CDA between systems through configurable channels. Agnotic Technologies builds, migrates and supports Mirth Connect channels for hospitals, labs and health tech teams, with error handling and monitoring designed in.
Mirth Connect (also sold as NextGen Connect) was open source up to version 4.5.2 and is commercially licensed from 4.6. Channels combine source and destination connectors with JavaScript transformer and filter steps for HL7 v2 (MLLP), FHIR, X12, delimited files, databases and web services.
The engine is easy to start and easy to get wrong. Production engines depend on error handling, reprocessing, alerting and maintainable channel design. We build channels with clean transformers, code templates and monitoring, so feeds keep flowing and failures stay visible.
How is a Mirth Connect engine laid out?
See how we design Mirth channel topologies, transformer logic, and error handling that scale with interface count.
Common failure modes
Where do Mirth Connect projects go wrong?
Challenge
Failed messages disappear silently
Agnotic approach
Error queues, alerting, and a reprocessing runbook so operations sees and recovers every failure.
Challenge
Transformer logic hides business rules
Agnotic approach
We keep transformers readable and factor shared logic into code templates with tests against real samples.
Challenge
Upgrades and migrations drop live feeds
Agnotic approach
Staged migration with parallel run and message-count reconciliation before decommissioning the old engine.
What do we build in Mirth Connect?
The exact interface-engine surface behind reliable healthcare message routing.
Channels & connectors
Source and destination connectors for MLLP/HL7 v2, HTTP/FHIR, TCP, file readers/writers, database, and web services.
Transformers & filters
JavaScript transformer and filter steps, code templates, and channel maps for HL7-to-FHIR, HL7-to-X12, and custom mappings.
Error handling & reprocessing
Message storage, error queues, automatic and manual reprocessing, and alerting so failed messages never disappear.
Standards routing
Route and transform HL7 v2 ADT/ORU/ORM/SIU, FHIR R4 resources, X12, and CDA across many endpoints from one engine.
Where it runs
What can our Mirth Connect integration services cover?
EHR interfacing
Route ADT, orders, and results between EHRs, ancillary systems, and apps.
Lab interfaces
Bidirectional ORM/ORU feeds to and from LIS and reference labs.
HL7-to-FHIR bridge
Expose legacy HL7 feeds as FHIR R4 for modern applications.
Legacy migration
Consolidate or replace aging interface engines without downtime.
Data aggregation
Funnel feeds from many sources into a warehouse or data lake.
Channels that stay maintainable at scale
Mirth is easy to start and hard to keep clean. We design for the fiftieth channel, not the first.

Our Process
How do we deliver a Mirth Connect project?
Channel design, transformer discipline, and monitoring treated as the real work.
1.
Discovery & interface map
We inventory every feed (source, destination, message type, and volume) and design the channel topology.
Feed-mapped
2.
Channel & transformer build
We build channels with clean transformers, reusable code templates, and consistent naming and error handling.
Maintainable
3.
Build & test
We validate channels against real message samples, including malformed and out-of-order messages.
Sample-validated
4.
Go-live & monitoring
Cutover with dashboards, alerting, and a reprocessing runbook so operations can act on failures.

Frequently Asked Questions
It depends on how many interfaces are in scope, how many message variants each feed carries, whether you are migrating from another engine, and how soon we get real sample messages and connectivity to each system. We inventory your feeds first, then give you a plan.
Cost scales with the number of channels, the complexity of transformations, and whether you need migration, alerting, and ongoing operations. A small set of HL7 interfaces is a smaller scope than a hospital-wide engine with dozens of channels and HL7-to-FHIR transformation. We scope against your interface list.
Since version 4.6, Mirth Connect needs a commercial license from NextGen Healthcare, priced per server rather than per interface, but there is no marketplace gatekeeper. The real approvals are on the systems it connects to: EHR interface agreements and, for embedded flows, vendor review. We plan those into the schedule.
Yes. Mirth Connect stores and routes PHI, so Agnotic signs a business associate agreement before we touch production messages. We build and test channels with synthetic or de-identified samples wherever we can.
Yes. A good first release is one feed end to end, for example ADT from your EHR into your app, with error queues, alerts and a reprocessing runbook. More channels follow once that one is stable in production.
AI tools help our engineers draft code and tests, but a person reviews every change, and it passes the same automated tests and security checks as any other code. Which tools may see your code or data is agreed with you at the start, and transformers are tested against real message samples before go-live.
Yes. Mirth is well suited to normalizing device, RPM, and telehealth data: we build channels that ingest device feeds, transform them to HL7 v2 or FHIR R4, and route them into the EHR or your platform's data store.
Yes. We build channels whose transformers map HL7 v2 segments onto FHIR R4 resources, using code templates for shared logic so the mappings stay consistent and testable across every interface.
