Why teams connect Attio and Notion

Sync what happens in Notion with the customer records in Attio, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Notion holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Properties, Blocks, Formula and Rollup properties, Users in Notion to Companies, Users, Deals, Workspaces in Attio with bi-directional, real-time sync. Activity and record changes in Notion update the matching contact or account in Attio, and CRM data flows the other way wherever Notion can store and use it.

Common use cases

  • 01 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.
  • 02 Sync a Notion content-calendar database with Jira or Linear by mapping status and date properties both directions.
  • 03 Keep Attio aligned with a billing system or ERP on customer records and plan status.
  • 04 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.

Common sync patterns

Where Notion supplies contact or company data

Enriched fields land directly on records in Attio, and refreshes keep them from going stale.

Where Notion can store CRM context: fields kept current

Owner, lifecycle stage, or account details from Attio sync into Notion, so people working there have the context without switching tools.

What you can sync between Attio 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.

Attio objects Notion objects How this pairing syncs
Users Synced with incremental and full sync per the Stacksync docs. Users Workspace members and bots referenced by people properties; read-only — users cannot be created or invited through the API. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
People Standard person object; synced with marketing tools and warehouse person tables. 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. People is specific to Attio and Files and attachments to Notion — each maps to any object or custom field on the other side.
Companies Standard company object; matched to billing and product accounts in two-way syncs. Pages The core content unit and also every row of a database; synced two-way as records, with typed properties mapping to table columns. Companies is specific to Attio and Pages to Notion — each maps to any object or custom field on the other side.
Deals Pipeline records; read out for revenue reporting and written to from automation. 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. Deals is specific to Attio and Databases / Data sources to Notion — each maps to any object or custom field on the other side.
Workspaces Synced with incremental and full sync per the Stacksync docs. Properties Typed columns on a page — title, rich_text, number, select, multi_select, date, people, relation, status, checkbox, URL. Read and written both ways. Workspaces is specific to Attio and Properties to Notion — each maps to any object or custom field on the other side.
Custom objects Workspace-defined objects that behave like standard ones in the API. Blocks The page body — paragraphs, headings, to-dos, tables — nested as children and fetched recursively, separate from a page's properties. Custom objects is specific to Attio and Blocks to Notion — each maps to any object or custom field on the other side.

How changes propagate between Attio 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.

Attio Notion Sub-second propagation

DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.

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

Notion Attio Sub-second propagation
