What Stacksync syncs in Notion.

These objects sync between Notion and any connected system, with field-level mapping and conflict resolution. Custom fields are picked up from the live schema where Notion exposes them.

Pages
The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns.
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.
Properties
Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways.
Blocks
The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties.
Formula and Rollup properties
Values computed by Notion from other fields; read-only, so they are pulled out for reporting but never written back.
Users
Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API.
Comments
Page and inline discussion threads; can be read and created, useful for surfacing Notion activity in another system.
Files and attachments
File-property and file-block values. Notion-hosted URLs are temporary and expire, so files are re-fetched or copied at sync time.
API surface

How Stacksync connects to Notion.

The connector runs on Notion's native API. Stacksync manages authentication, rate limits, retries, and schema changes so your team does not maintain integration code.

Connection
REST API (api.notion.com/v1)
Authentication
OAuth 2.0 for public integrations, or an internal integration secret (bearer token); every request must send a Notion-Version header
Change detection
Workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created; HMAC-SHA256 signed) plus polling on each page's last_edited_time
Rate limits
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.

At scale

Event queues

Handle millions of events per minute without losing a single Notion record.

Observability

Monitoring

Track your Notion sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions.

Use cases

What teams run on the Notion connector.

Notion is the all-in-one workspace where mid-market teams run docs, wikis, and lightweight databases for projects, CRM-lite tracking, content calendars, and OKRs. It is usually owned by operations, chiefs of staff, or product and project managers rather than IT, and spreads bottom-up across teams. Because non-technical teams keep working data in Notion databases — each row a page with typed properties — it becomes a system of engagement that other tools need to read from and write back to.

  • Operations / RevOps
  • Product and project managers
  • Chiefs of staff and founders
  • Internal tools / data engineering
  • Knowledge management leads

  1. 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.

  2. Mirror a Notion CRM-lite database's Pages and select/relation properties into Salesforce or HubSpot so lightweight tracking stays aligned with the CRM system of record.

  3. Push rows from a warehouse or another database into a Notion data source as Pages so ops and leadership read live metrics in a familiar Notion view.

  4. Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.

  5. Read Notion wiki Pages and their Blocks into a database or search index for internal knowledge retrieval.

  6. Two-way sync a Notion projects or tasks data source with a Postgres table so engineers query and update records in SQL while the team edits Pages in Notion; status, date, and assignee properties map in both directions.

How it works

Set up Notion in minutes, without APIs.

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

FAQ

Notion connector FAQ

What can I sync with the Notion connector?

Notion's core objects — Pages, Databases / Data sources, Properties, Blocks and custom fields — can sync with any of 302 other systems. Every integration is real-time and bidirectional, with field-level mapping and conflict resolution.

How does Stacksync connect to Notion?

Via REST API (api.notion.com/v1), authenticated with OAuth 2.0 for public integrations, or an internal integration secret (bearer token); every request must send a Notion-Version header. Changes are detected as follows — workspace webhooks (page.created, page.content_updated, data_source.schema_updated, comment.created; HMAC-SHA256 signed) plus polling on each page's last_edited_time. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Notion connector two-way?

Yes. Changes made in Notion propagate to the connected system and vice versa, in milliseconds. One-way flows are also supported when a direction should stay read-only.

How long does a Notion integration take to set up?

Most Notion integrations go live in minutes: authenticate Notion and the other system, pick objects and fields, and enable the sync. No code and no infrastructure to manage.

Is Notion data secure in transit?

Stacksync is SOC 2 Type II, ISO 27001, GDPR and HIPAA compliant. Notion data is encrypted in transit, and a zero-persistent-storage architecture means records are not retained after a sync operation.
