Why teams connect InterSystems IRIS and Notion

Mirror Notion's data into InterSystems IRIS 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 Notion 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 InterSystems IRIS.

Stacksync mirrors Files and attachments, Pages, Databases / Data sources, Properties from Notion into Views, Schemas, Persistent Classes, Globals in InterSystems IRIS 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 Notion, so the tool and the database never disagree.

Common use cases

  • 01 Read Notion wiki Pages and their Blocks into a database or search index for internal knowledge retrieval.
  • 02 Two-way sync a Notion projects or tasks data source with a Postgres table so engineers work in SQL while the team edits Pages in Notion, mapping status, date, and assignee properties both ways.
  • 03 Keep reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools
  • 04 Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing

Common sync patterns

React to changes as they happen

Updates in Notion arrive as row changes in InterSystems IRIS, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Notion with a query

Records from Notion are ordinary rows in InterSystems IRIS; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between InterSystems IRIS and Notion

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.

InterSystems IRIS objects Notion objects How this pairing syncs
Schemas Schema organization scopes which tables a sync connection can see. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Schemas is specific to InterSystems IRIS and Pages to Notion — each maps to any object or custom field on the other side.
Persistent Classes Object-model classes project to tables, so class data is reachable through SQL. Databases / Data sources Collections of pages with a typed property schema. Since the 2025-09-03 API a database is a container holding one or more data sources; syncs target a specific data_source_id. Persistent Classes is specific to InterSystems IRIS and Databases / Data sources to Notion — each maps to any object or custom field on the other side.
Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Globals is specific to InterSystems IRIS and Properties to Notion — each maps to any object or custom field on the other side.
Namespaces Namespaces partition databases and determine the connection context for integrations. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Namespaces is specific to InterSystems IRIS and Blocks to Notion — each maps to any object or custom field on the other side.
Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Stored Procedures is specific to InterSystems IRIS and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.
Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs. Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Tables is specific to InterSystems IRIS and Users to Notion — each maps to any object or custom field on the other side.

How changes propagate between InterSystems IRIS and Notion

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.

InterSystems IRIS Notion Interval-based propagation

DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).

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

Notion InterSystems IRIS Sub-second propagation

DetectionNotion notifies Stacksync of record changes through webhook events. Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created.

DeliveryEach detected change is applied to InterSystems IRIS as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • InterSystems IRIS: Constrained by database resources rather than published API rate limits.
  • Notion: Average of ~3 requests/second per integration with some bursts; 429 with a Retry-After header when exceeded. Payloads capped at 500 KB and 1000 block elements.
