Why teams connect eClinicalWorks and Microsoft Graph

Connect the tickets, records, and events in eClinicalWorks to the systems engineering runs in Microsoft Graph, kept current in real time and in both directions.

eClinicalWorks is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Microsoft Graph is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.

Stacksync syncs Practitioners, Observations, Medications, Allergies in eClinicalWorks with Contacts, Drive items (OneDrive & SharePoint), Teams messages and chats, Planner tasks in Microsoft Graph field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.

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 Two-way sync Users and Groups between Microsoft Entra ID and an HRIS or Postgres so joiners, movers, and leavers provision and deprovision accounts and group memberships automatically.
  • 04 Sync Outlook Calendar events and Contacts two-way with a CRM so reps' meetings and the people they meet stay aligned across both systems.

Common sync patterns

Where Microsoft Graph is the directory or identity source: one set of users

People and accounts in eClinicalWorks stay matched to the users in Microsoft Graph, so access, provisioning, and org changes propagate instead of being keyed in twice.

Where Microsoft Graph watches operations: live volumes for visibility

Open items, throughput, and error counts from eClinicalWorks replicate into Microsoft Graph, so the operational view reflects what is actually happening in the business.

One shared record across both systems

Where both systems keep records for the same contacts, items, or users, a correction in either updates the other, ending dual maintenance and keeping IDs aligned for every other flow.

What you can sync between eClinicalWorks and Microsoft Graph

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 Microsoft Graph objects How this pairing syncs
Appointments Scheduling records available via FHIR and HL7 SIU messages, synced for reminders and outreach. Teams messages and chats Channel messages and chats via /teams/{id}/channels and /chats; read message history and post new messages for alerts and archiving. Appointments is specific to eClinicalWorks and Teams messages and chats to Microsoft Graph — each maps to any object or custom field on the other side.
Encounters Visit records tying diagnoses, providers, and billing context together. Planner tasks Plans, buckets, and tasks via /planner; read and write task status, assignments, and due dates to keep project state in sync. Encounters is specific to eClinicalWorks and Planner tasks to Microsoft Graph — each maps to any object or custom field on the other side.
Practitioners Provider records used to keep directories and scheduling systems consistent. Users Entra ID user accounts read and written via /users; create, update profile attributes, and enable or disable accounts with User.ReadWrite.All. Practitioners is specific to eClinicalWorks and Users to Microsoft Graph — 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. Groups and memberships Microsoft 365 and security groups via /groups; read and write name, owners, and add/remove members, with membership deltas surfaced by delta query. Observations is specific to eClinicalWorks and Groups and memberships to Microsoft Graph — each maps to any object or custom field on the other side.
Medications Prescription and medication-list data within the patient record. Mail messages (Outlook) Messages via /users/{id}/messages; read and create drafts, update, and send with the sendMail action, so this surface is fully read-write. Medications is specific to eClinicalWorks and Mail messages (Outlook) to Microsoft Graph — each maps to any object or custom field on the other side.
Allergies Allergy and intolerance entries in the clinical record. Calendar events Outlook events via /users/{id}/events; read and write meetings, attendees, and recurrence, and accept or decline invitations. Allergies is specific to eClinicalWorks and Calendar events to Microsoft Graph — each maps to any object or custom field on the other side.

How changes propagate between eClinicalWorks and Microsoft Graph

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 Microsoft Graph 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 written to Microsoft Graph through its API, with automatic retries and rate-limit backoff.

Microsoft Graph eClinicalWorks Sub-second propagation

DetectionMicrosoft Graph notifies Stacksync of record changes through webhook events. Delta query (change tracking) returns created, updated, and deleted items since the last deltaLink for users, groups, mail, events, contacts, and.

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.
  • Microsoft Graph: Throttled per app and per tenant, returning HTTP 429 with a Retry-After header; limits vary by service — the Outlook mail service allows about 10,000 requests per 10 minutes per app per mailbox with up to 4 concurrent requests, and delta and subscription tokens expire and must be renewed.

How the eClinicalWorks and Microsoft Graph connectors work

eClinicalWorks

Integration surface
FHIR R4 REST API plus HL7 v2 interfaces (ADT, SIU, ORU) through an interface engine
Authentication
OAuth 2.0 / SMART on FHIR for the FHIR API; site-configured credentials for HL7 interface connections
Change detection
HL7 interface feeds push event messages as they occur; the FHIR API is polled
Capabilities

Microsoft Graph

Integration surface
Microsoft Graph unified REST API (v1.0 and beta) at graph.microsoft.com, spanning Microsoft 365 services — Entra ID, Outlook mail and calendar, OneDrive and SharePoint, Teams, and Planner; supports JSON $batch (up to 20 requests per call).
Authentication
OAuth 2.0 via the Microsoft identity platform (Microsoft Entra ID). An app registration holds delegated or application (app-only) scopes such as Mail.ReadWrite, Calendars.ReadWrite, Files.ReadWrite.All, User.ReadWrite.All, and Group.ReadWrite.All; application permissions require tenant admin consent.
Change detection
Delta query (change tracking) returns created, updated, and deleted items since the last deltaLink for users, groups, mail, events, contacts, and driveItems; change-notification subscriptions (webhooks) POST near-real-time notifications to a notification URL and must be renewed before they expire.
Capabilities

Rate limits
Throttled per app and per tenant, returning HTTP 429 with a Retry-After header; limits vary by service — the Outlook mail service allows about 10,000 requests per 10 minutes per app per mailbox with up to 4 concurrent requests, and delta and subscription tokens expire and must be renewed.
