Why teams connect Microsoft 365 and Postgres Heroku
Mirror Microsoft 365's data into Postgres Heroku 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 Microsoft 365 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 Postgres Heroku.
Stacksync mirrors Contacts, OneDrive Files (driveItems), SharePoint Sites & Lists, Teams from Microsoft 365 into Tables, Views, Materialized Views, Schemas in Postgres Heroku 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 Microsoft 365, so the tool and the database never disagree.
Common use cases
- Archive mail and file metadata into a warehouse for compliance and activity analytics.
- Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
- Sync Heroku Postgres into a warehouse for reporting without running ETL dynos
- Keep several Heroku app databases aligned with one system of record
Read Microsoft 365 with a query
Records from Microsoft 365 are ordinary rows in Postgres Heroku; join them, index them, and use them in application logic without touching the vendor API.
Automate Microsoft 365 from your codebase
Write to the synced tables in Postgres Heroku and Stacksync propagates the change into Microsoft 365, replacing custom integration code.
React to changes as they happen
Updates in Microsoft 365 arrive as row changes in Postgres Heroku, so triggers, jobs, and services can respond in near real time.
What you can sync between Microsoft 365 and Postgres Heroku
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.
| Microsoft 365 objects | Postgres Heroku objects | |
|---|---|---|
| Teams Team and membership data provisioned from upstream systems. | Schemas Namespaces that scope which tables a sync reads and writes. | |
| Planner & To Do Tasks Task items synced with project and work-management tools. | Primary and Unique Keys Match keys for idempotent upserts from connected systems. | |
| Users Entra ID user accounts synced with HR and identity systems. | JSONB Columns Semi-structured payloads for nested SaaS objects and metadata. | |
| Groups Microsoft 365 and security groups kept aligned with org structure and access rules. | Sequences Generate surrogate keys for rows created by inbound syncs. | |
| Mail Messages Exchange Online messages read for logging, archiving, or activity capture. | Follower Databases Heroku-managed read replicas usable as low-impact sync sources. | |
| Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. | Tables Standard Postgres tables; the primary two-way sync target for app data. |

How the Microsoft 365 and Postgres Heroku connectors work
Microsoft 365
- Integration surface
- REST API (Microsoft Graph)
- Authentication
- OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions
- Change detection
- Graph change notifications (webhooks) plus delta queries for incremental sync
- Capabilities
- read · write · webhooks
Postgres Heroku
- Integration surface
- SQL wire protocol (standard PostgreSQL)
- Authentication
- Database credentials from the Heroku DATABASE_URL config var; SSL required
- Change detection
- Trigger-based capture or polling in most configurations; log-based logical replication availability depends on plan and Heroku's managed server settings
- Capabilities
- read · write
- Rate limits
- No API rate limits; connection counts and performance are bounded by the Heroku Postgres plan

FAQ
Microsoft 365 and Postgres Heroku integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Microsoft 365 and Postgres Heroku: authenticate both systems, choose the objects to sync (such as Microsoft 365's Teams and Planner & To Do Tasks), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Microsoft 365 and Postgres Heroku: Read Microsoft 365 with a query; Automate Microsoft 365 from your codebase; React to changes as they happen. Records from Microsoft 365 are ordinary rows in Postgres Heroku; join them, index them, and use them in application logic without touching the vendor API.
-
Microsoft 365: REST API (Microsoft Graph). Authentication: OAuth 2.0 via Microsoft Entra ID, with delegated or application permissions. Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. Stacksync manages authentication, retries, and rate limits on both sides.
-
Microsoft 365: Delta queries return only resources changed since the last sync token, which keeps incremental syncs cheap on large tenants. Postgres Heroku: All connections require SSL, and server-level settings such as replication configuration are controlled by Heroku rather than the user. Stacksync's field mapping accounts for these differences between Microsoft 365 and Postgres Heroku without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Microsoft 365 and Postgres Heroku records are not retained after a sync operation.
