Why teams connect Google Cloud Platform and Microsoft Graph

Close the gap between analytics and operations: Google Cloud Platform holds the record while Microsoft Graph runs the day-to-day work, and Stacksync keeps the two in step in real time, in both directions.

Google Cloud Platform is the central store where teams keep Pub/Sub topics, Firestore documents, Spanner tables, BigQuery datasets for reporting and analysis; Microsoft Graph runs the operational side of engineering work — tracking issues, moving messages and events, watching systems, and managing users and access. The two overlap wherever the same operational data matters to both: the Planner tasks, Users, Groups and memberships, Mail messages (Outlook) produced in Microsoft Graph are exactly what analysts want to measure in Google Cloud Platform, and the curated rows in Google Cloud Platform are what should drive the next action in Microsoft Graph. When that overlap is bridged by nightly ETL or hand-written scripts, dashboards lag a day behind reality and the tools that should react to warehouse signals never see them.

Stacksync syncs Pub/Sub topics, Firestore documents, Spanner tables, BigQuery datasets in Google Cloud Platform with Planner tasks, Users, Groups and memberships, Mail messages (Outlook) in Microsoft Graph field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync matches records on a stable external key, keeps every copy consistent, and resolves conflicts by rules you set — so analytics and operations work from the same current data instead of two drifting copies.

Common use cases

  • 01 Publish change events to Pub/Sub so downstream services react to record updates as they happen.
  • 02 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.
  • 03 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

Warehouse signals reach Microsoft Graph

A row scored, flagged, or enriched in Google Cloud Platform creates or updates the matching record in Microsoft Graph, so the operational tool acts on the same data the analysts already see.

Backfill history, then stay live

Load the existing set of Planner tasks, Users, Groups and memberships, Mail messages (Outlook) into Google Cloud Platform once, then keep it current with every change — you get full history plus real-time updates without a separate pipeline.

No batch jobs to babysit

New and changed records move field by field the moment they change, replacing scheduled ETL and one-off scripts that fail quietly and leave stale rows behind.

What you can sync between Google Cloud Platform 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.

Google Cloud Platform objects Microsoft Graph objects How this pairing syncs
Firestore documents Document data read and written through the Firestore API for app-facing syncs. 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 Google Cloud Platform and Calendar events to Microsoft Graph — each maps to any object or custom field on the other side.
Spanner tables Strongly consistent relational tables accessed via SQL for transactional workloads. Contacts Personal Outlook contacts via /users/{id}/contacts; full create, read, update, delete, synced two-way with CRM person records. Spanner tables is specific to Google Cloud Platform and Contacts to Microsoft Graph — each maps to any object or custom field on the other side.
BigQuery datasets Namespaces that group tables; syncs target tables within a dataset. 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. BigQuery datasets is specific to Google Cloud Platform and Drive items (OneDrive & SharePoint) to Microsoft Graph — each maps to any object or custom field on the other side.
BigQuery tables The primary analytics destination, written through load jobs or the Storage Write API and queried with SQL. 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. BigQuery tables is specific to Google Cloud Platform and Teams messages and chats to Microsoft Graph — each maps to any object or custom field on the other side.
Cloud SQL databases Managed Postgres, MySQL, and SQL Server instances synced like ordinary relational databases. Planner tasks Plans, buckets, and tasks via /planner; read and write task status, assignments, and due dates to keep project state in sync. Cloud SQL databases is specific to Google Cloud Platform and Planner tasks to Microsoft Graph — each maps to any object or custom field on the other side.
Cloud Storage objects Staging area for file-based bulk loads into BigQuery and other services. Users Entra ID user accounts read and written via /users; create, update profile attributes, and enable or disable accounts with User.ReadWrite.All. Cloud Storage objects is specific to Google Cloud Platform and Users to Microsoft Graph — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Platform 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.

Google Cloud Platform Microsoft Graph Sub-second propagation

DetectionGoogle Cloud Platform pushes changes as they happen — webhook events backed by change data capture. Varies by service: log-based CDC on Cloud SQL (logical replication or binlog, also via Datastream), Pub/Sub for event delivery, polling for BigQuery.

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

Microsoft Graph Google Cloud Platform 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 applied to Google Cloud Platform as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google Cloud Platform: Quotas are set per service and per project; BigQuery, Pub/Sub, and Cloud SQL each enforce their own 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.

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.
