Why teams connect IBM AS/400 and Notion

Mirror Notion's data into IBM AS/400 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 IBM AS/400.

Stacksync mirrors Comments, Files and attachments, Pages, Databases / Data sources from Notion into Physical files (tables), Logical files (views), Members, Rows / records in IBM AS/400 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 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • 04 Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.

Common sync patterns

Automate Notion from your codebase

Write to the synced tables in IBM AS/400 and Stacksync propagates the change into Notion, replacing custom integration code.

React to changes as they happen

Updates in Notion arrive as row changes in IBM AS/400, 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.

What you can sync between IBM AS/400 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.

IBM AS/400 objects Notion objects How this pairing syncs
Journals and journal receivers The change log that enables log-based CDC on journaled files. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Journals and journal receivers is specific to IBM AS/400 and Pages to Notion — each maps to any object or custom field on the other side.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. 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. Data queues is specific to IBM AS/400 and Databases / Data sources to Notion — each maps to any object or custom field on the other side.
Libraries The schema-equivalent containers that scope which files a sync reads. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Libraries is specific to IBM AS/400 and Properties to Notion — each maps to any object or custom field on the other side.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Physical files (tables) is specific to IBM AS/400 and Blocks to Notion — each maps to any object or custom field on the other side.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Formula and Rollup properties Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back. Logical files (views) is specific to IBM AS/400 and Formula and Rollup properties to Notion — each maps to any object or custom field on the other side.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Members is specific to IBM AS/400 and Users to Notion — each maps to any object or custom field on the other side.

How changes propagate between IBM AS/400 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.

IBM AS/400 Notion Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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

Notion IBM AS/400 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 IBM AS/400 as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
  • 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.
