Why teams connect eClinicalWorks and IBM AS/400

Mirror eClinicalWorks's data into IBM AS/400 so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like eClinicalWorks through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in IBM AS/400.

Stacksync mirrors Practitioners, Observations, Medications, Allergies from eClinicalWorks into Physical files (tables), Logical files (views), Members, Rows / records in IBM AS/400 and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into eClinicalWorks, so the tool and the database never disagree.

Common use cases

  • 01 Land encounter and billing-context data in a warehouse for utilization and revenue-cycle reporting.
  • 02 Feed appointment events to reminder and messaging platforms to reduce no-shows.
  • 03 Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • 04 Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.

Common sync patterns

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read eClinicalWorks with a query

Records from eClinicalWorks are ordinary rows in IBM AS/400; join them, index them, and use them in application logic without touching the vendor API.

Automate eClinicalWorks from your codebase

Write to the synced tables in IBM AS/400 and Stacksync propagates the change into eClinicalWorks, replacing custom integration code.

What you can sync between eClinicalWorks and IBM AS/400

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

eClinicalWorks objects IBM AS/400 objects How this pairing syncs
Diagnostic reports Structured result reports grouping observations for a study or panel. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Diagnostic reports is specific to eClinicalWorks and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side.
Patients Demographic records exposed via FHIR Patient resources and HL7 ADT feeds; the anchor for all clinical syncs. Logical files (views) Indexed or filtered views over physical files, usable as read sources. Patients is specific to eClinicalWorks and Logical files (views) to IBM AS/400 — each maps to any object or custom field on the other side.
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Appointments is specific to eClinicalWorks and Members to IBM AS/400 — each maps to any object or custom field on the other side.
Encounters Visit records tying diagnoses, providers, and billing context together. Rows / records The unit of read and write, accessed via SQL or record-level access. Encounters is specific to eClinicalWorks and Rows / records to IBM AS/400 — each maps to any object or custom field on the other side.
Practitioners Provider records used to keep directories and scheduling systems consistent. Journals and journal receivers The change log that enables log-based CDC on journaled files. Practitioners is specific to eClinicalWorks and Journals and journal receivers to IBM AS/400 — each maps to any object or custom field on the other side.
Observations Labs and vitals, delivered via FHIR resources or HL7 ORU result messages. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Observations is specific to eClinicalWorks and Data queues to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between eClinicalWorks and IBM AS/400

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

eClinicalWorks IBM AS/400 Interval-based propagation

DetectionStacksync polls eClinicalWorks for changes on an incremental schedule, reading only records changed since the previous pass. HL7 interface feeds push event messages as they occur.

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 eClinicalWorks Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

DeliveryEach detected change is written to eClinicalWorks through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • eClinicalWorks: Subject to the platform's API rate limits and interface throughput agreements.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
