SendGrid Push appointment changes, lab results, and prescription updates between Epic, Cerner, and your patient portal the moment they happen, two-way and in real time, so neither side ever shows stale data.
Your portal and your EHR were built by different vendors and never meant to share state. The handoffs break in predictable places.
A result posts in Epic at 9am and reaches the portal that night, or never. Patients call the front desk for numbers their chart already has, and clinicians field the same questions twice.
Most HL7 feeds run one direction. A patient cancels in the app, but Cerner still holds the slot, so the schedule and the portal disagree all morning.
When a record crosses from EHR to app, point-to-point scripts log nothing. An auditor asks who accessed a result and when, and nobody can answer with confidence.
Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.
Changes made in one platform automatically update across all connected systems in real time, eliminating data silos and reducing errors.
Stop building brittle API scripts. With Stacksync, you can trigger complex automated workflows using simple SQL commands.
Expose every enterprise system to your agents through a single MCP layer. Claude, ChatGPT and Gemini get production-grade tools without custom glue code.
Handle massive traffic spikes without losing a single event. Queues buffer your data during surges, ensuring strict ordering and reliable delivery.
Interact with your CRM, ERP, and payment tools as if they were just another table in your database. Say goodbye to rate limits and complex API documentation.
Transform legacy EDI complexity into simple database interactions. Stacksync automatically parses incoming EDI documents directly into your database tables.
Stacksync ships pre-built two-way connectors for the EHRs, integration engines, and portals patient data flows through, with field-level conflict policies, replay, and full audit logging.

Oracle DB As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
Immediately get alerted about record syncing issues over email, Slack, PagerDuty and WhatsApp. Resolve issues from a centralized dashboard with retry and revert options.
Securely connects to your systems with:
How fast does a lab result reach the patient app?
Sub-second when the EHR emits an HL7 or FHIR event; otherwise 1–60s on a configurable poll. Patients see results the moment the clinician releases them, not after a nightly feed.
Is the sync two-way, so reschedules flow back to the EHR?
Yes. A cancel or reschedule in the portal writes back to Epic or Cerner in real time, and field-level conflict policies decide which side wins if both change at once.
How do you keep PHI access auditable?
Every record movement is logged with source, destination, fields, and timestamp, and each event is replayable. You can show an auditor exactly which PHI moved where and when.
Can we map custom EHR and FHIR fields?
Yes. Epic Clarity columns, FHIR R4 extensions, and your portal's custom fields map in the visual mapper alongside standard demographics and sync the same way.
