NextGen Healthcare Integration Services: API and Mirth
NextGen integration connects your product, lab or organization to NextGen Healthcare, a widely used ambulatory EHR vendor serving medical groups and specialty practices. NextGen also owns Mirth Connect, the integration engine behind many healthcare interfaces, which makes integration expertise across both especially valuable. Taction Software builds NextGen API integrations, FHIR connections, HL7 interfaces and Mirth-based channels for vendors and practices. Talk to our NextGen integration team about your workflows, timelines and the most practical approach for your product. Scoping calls are free.
NextGen Healthcare Integration Options
NextGen Healthcare offers integration paths through APIs, FHIR endpoints and HL7 interfaces, with differences between its products, including NextGen Enterprise and NextGen Office. Choosing the right approach depends on the product your customers use, the workflows you support and whether real-time events are needed. Our wider EHR/EMR integration services apply consistent design patterns, so NextGen integrations fit alongside connections to other EHR vendors cleanly. Each option is summarized below with practical guidance.
NextGen Enterprise and NextGen Office
NextGen Enterprise serves larger medical groups, while NextGen Office targets smaller practices with a cloud-based product. Integration options, APIs and processes can differ, so confirm which product each customer uses.
NextGen API Integration
NextGen provides APIs supporting workflows such as patient demographics, scheduling, clinical data and documents. Access typically involves developer program registration, agreements and customer enablement before production use. Plan these steps early.
Certified FHIR R4 APIs
NextGen offers certified FHIR R4 APIs aligned with US Core and USCDI for standardized data access. Many integrations combine FHIR reads with proprietary APIs or HL7 feeds for broader workflow coverage.
HL7 v2 Interfaces
HL7 interfaces support ADT, orders, results, scheduling and charges between NextGen and external systems. They remain essential for labs, diagnostic services and billing partners needing reliable, event-driven data exchange. Plan capacity accordingly.
Developer Program Access
NextGen's developer and partner programs provide documentation, sandbox resources and commercial terms for vendors. Program requirements change over time, so review current details directly with NextGen before planning. Budget for program fees.
The NextGen and Mirth Connect Connection
NextGen Healthcare owns Mirth Connect, one of the most widely deployed healthcare integration engines. Many NextGen practices and partners use Mirth for interfaces, and NextGen's commercial Mirth products support integration workflows across its customer base. This makes Mirth expertise directly relevant to NextGen integration projects. Our Mirth Connect consulting team brings deep channel development, upgrade and monitoring experience to NextGen environments and partner integrations. The practical implications for integration projects are explained below.
Why Mirth Matters for NextGen Projects
Because NextGen owns Mirth, many NextGen-connected environments already run Mirth channels. Integration partners with strong Mirth skills can extend, troubleshoot and optimize those interfaces efficiently. That familiarity shortens troubleshooting and reduces delivery risk.
Mirth Licensing Considerations
NextGen moved newer Mirth Connect releases to a commercial licence in 2025. Organizations should confirm licensing for their environment, especially when planning upgrades, new interfaces or support agreements. Budget renewals carefully.
Building NextGen Interfaces in Mirth
Mirth channels can receive, transform and route HL7 messages between NextGen and labs, imaging systems, billing partners and digital health products, with monitoring, acknowledgements and error handling built in. Channels stay documented.
Upgrading Existing Mirth Environments
Many NextGen-connected organizations run older Mirth versions. We plan upgrades with channel inventories, compatibility testing and parallel runs, protecting interfaces that practices rely on every day. Rollback plans are always tested beforehand.
Monitoring NextGen Interfaces
Interfaces need alerting for stopped channels, queue growth and errors. Well-monitored Mirth environments catch issues before missing results or scheduling updates affect practice staff and patients. Alerts reach on-call engineers quickly.
Our NextGen Integration Services
As a NextGen integration company, we help digital health vendors, labs and practices build and support reliable NextGen connections. We combine API development, FHIR integration, HL7 interface work and Mirth expertise, choosing the right approach for each workflow. Our FHIR integration and HL7 integration teams test against real message samples and customer environments, not only documentation or sandbox assumptions. Each service is outlined below, and every engagement includes full documentation and knowledge transfer.
NextGen API Integration Development
We build integrations using NextGen APIs for demographics, scheduling, clinical data and documents, handling authentication, rate limits, pagination and errors across multiple customer practices. Each workflow is tested against real customer data variations.
NextGen HL7 Interface Development
We build ADT, order, result, scheduling and charge interfaces with mapping, acknowledgements and identity matching, coordinating specifications and testing with NextGen customers and vendor teams. Every interface is monitored after go-live.
FHIR Integration
We integrate NextGen's certified FHIR endpoints for standardized data access, validating US Core resources and combining FHIR with HL7 or proprietary APIs where workflows need more coverage. Conformance is tested.
Middleware and Data Normalization
Our healthcare API development team builds middleware normalizing NextGen data into your internal model, supporting other EHR vendors without rewriting product code. Every flow is logged, audited and monitored for support teams continuously.
Practice Onboarding Support
We prepare security documentation, specifications and test plans, and coordinate with practice staff, helping each new NextGen customer approve and activate your integration efficiently. Each rollout becomes faster and more predictable.
NextGen Integration Timelines
NextGen integration timelines depend on the product customers use, developer program steps, customer approvals and interface scheduling. API integrations may reach production faster than HL7 interfaces requiring customer interface work. The phases below reflect common patterns and are indicative planning ranges, not guarantees. Later practice rollouts usually move faster once specifications, documentation and onboarding processes are proven through the first successful customer deployment and stabilization period. Each phase is summarized below.
Discovery and Program Setup: 2–4 Weeks
Confirm customer products, workflows and integration surfaces, then complete developer program registration and agreements. Early clarity prevents rework later in development and customer onboarding. Decisions are documented for the whole team.
Development and Sandbox Testing: 4–10 Weeks
Build API, FHIR or HL7 components and test with sandbox or synthetic data. Duration depends on workflow count, write requirements and whether Mirth channels need building. Test edge cases early.
Customer Approval and Configuration: 3–8 Weeks
Practices review security and data use, then configure access or interfaces. Documentation quality and customer IT capacity strongly influence how quickly this phase completes. Start approvals during development to save time.
Testing and Go-Live: 2–6 Weeks
Validate integrations in customer environments, confirm results with practice staff and schedule go-live. Monitor interfaces closely afterward, resolving issues quickly as real volumes increase. Engineers remain on call throughout stabilization.
