Why teams connect Firebase and Microsoft Graph

Keep Firebase and Microsoft Graph in step: the rows in your database and the Drive items (OneDrive & SharePoint), Teams messages and chats, Planner tasks, Users your engineering tools track stay consistent in real time, in both directions.

Firebase is where your application's durable data lives; Microsoft Graph is where engineering and operations teams track the issues, events, messages, or identities that run alongside it. The two overlap constantly, a row should open a ticket, an alert should land as a record, a user in one should exist in the other, but bridging them today means per-tool integration code: auth, webhooks, pagination, rate limits, and retries, built and maintained separately for every tool.

Stacksync syncs Cloud Storage Objects, Cloud Functions Triggers, Firestore Collections, Firestore Documents in Firebase with Drive items (OneDrive & SharePoint), Teams messages and chats, Planner tasks, Users in Microsoft Graph field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set, so the database and the tooling around it never drift apart.

Common use cases

  • 01 Combine Firebase Authentication users with billing and CRM records into one customer table.
  • 02 Replace one-off Cloud Functions export code with managed, continuous sync.
  • 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

React to changes on either side in near real time

Updates in Microsoft Graph arrive as row changes in Firebase, and writes to Firebase propagate to Microsoft Graph within seconds, so triggers, jobs, and alerts fire without polling.

Where Microsoft Graph manages users or groups: keep identity aligned

Directory and identity records in Microsoft Graph stay matched to the users or owners table in Firebase, so provisioning and de-provisioning flow from one source.

Turn rows into the records your tools track

A new or changed row in Firebase creates or updates the matching record in Microsoft Graph, whether that is an issue, an event, a message, or a user, so the tool reflects the database without a custom API job.

What you can sync between Firebase 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.

Firebase objects Microsoft Graph objects How this pairing syncs
Firestore Documents Schemaless JSON-like records, the primary unit synced to and from external systems. Calendar events Outlook events via /users/{id}/events; read and write meetings, attendees, and recurrence, and accept or decline invitations. Firestore Documents is specific to Firebase and Calendar events to Microsoft Graph — each maps to any object or custom field on the other side.
Subcollections Nested collections under documents, typically flattened into related tables during sync. Contacts Personal Outlook contacts via /users/{id}/contacts; full create, read, update, delete, synced two-way with CRM person records. Subcollections is specific to Firebase and Contacts to Microsoft Graph — each maps to any object or custom field on the other side.
Realtime Database Nodes JSON tree paths in the older Realtime Database, synced by path. Drive items (OneDrive & SharePoint) Files and folders via /drives and /me/drive; read and write items, upload and download content, and read per-item metadata. Realtime Database Nodes is specific to Firebase and Drive items (OneDrive & SharePoint) to Microsoft Graph — each maps to any object or custom field on the other side.
Authentication Users User accounts read into CRMs and warehouses for customer records. 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. Authentication Users is specific to Firebase and Teams messages and chats to Microsoft Graph — each maps to any object or custom field on the other side.
Cloud Storage Objects Files referenced from documents; usually synced as metadata plus URLs. Planner tasks Plans, buckets, and tasks via /planner; read and write task status, assignments, and due dates to keep project state in sync. Cloud Storage Objects is specific to Firebase and Planner tasks to Microsoft Graph — each maps to any object or custom field on the other side.
Cloud Functions Triggers Server-side hooks that fire on document changes and can push updates outward. Users Entra ID user accounts read and written via /users; create, update profile attributes, and enable or disable accounts with User.ReadWrite.All. Cloud Functions Triggers is specific to Firebase and Users to Microsoft Graph — each maps to any object or custom field on the other side.

How changes propagate between Firebase 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.

Firebase Microsoft Graph Interval-based propagation

DetectionStacksync polls Firebase for changes on an incremental schedule, reading only records changed since the previous pass. Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes.

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

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

Rate-limit considerations

  • Firebase: Subject to Firestore's documented operation quotas and per-document write throughput limits.
  • 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 Firebase and Microsoft Graph connectors work

Firebase

Integration surface
REST and gRPC APIs, typically accessed through the Firebase Admin SDK
Authentication
Google service account credentials (IAM) for server-side access; Firebase Auth tokens for client contexts
Change detection
Real-time snapshot listeners on Firestore queries and Cloud Functions triggers on document changes
Capabilities
read · write
Rate limits
Subject to Firestore's documented operation quotas and per-document write throughput limits

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
