What Stacksync syncs in Attio.

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

People
Standard person object; synced with marketing tools and warehouse person tables.
Companies
Standard company object; matched to billing and product accounts in two-way syncs.
Users
Synced with incremental and full sync per the Stacksync docs.
Deals
Pipeline records; read out for revenue reporting and written to from automation.
Workspaces
Synced with incremental and full sync per the Stacksync docs.
Custom objects
Workspace-defined objects that behave like standard ones in the API.
API surface

How Stacksync connects to Attio.

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

Connection
REST API
Authentication
Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key)
Change detection
Webhooks on record and list-entry events, with polling as a fallback
Rate limits
Subject to the platform's published API rate limits.

Transform legacy EDI complexity into simple database interactions.

Use cases

What teams run on the Attio connector.

Attio is bought by RevOps and GTM operations teams at startups and scale-ups that want a collaborative CRM with a flexible data model built on People, Companies, and custom objects. It typically serves as the system of record for pipeline and relationship data shared across go-to-market teams. Because teams model their own entities in Attio, the workspace accumulates both standard CRM records and business-specific objects, making it a hub other systems need to read from and write to.

  • RevOps
  • GTM operations at startups
  • Data engineering

  1. Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.

  2. Write product usage and enrichment data into Attio attributes so GTM teams work from live account signals.

  3. Keep Attio aligned with a billing system or ERP on customer records and plan status.

  4. Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.

  5. Run a two-way dual-run when migrating to Attio from another CRM.

  6. Two-way sync of People and Companies with a Postgres or warehouse table so data engineering enriches records with product usage and writes scores back into Attio for GTM teams.

FAQ

Attio connector FAQ

What can I sync with the Attio connector?

Attio's core objects — People, Companies, Users, Deals 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 Attio?

Via REST API, authenticated with Guided in-app connection ("Attio CRM" connection created in a few clicks, "without any coding required"); the docs do not name the underlying auth mechanism (OAuth vs API key). Changes are detected as follows — webhooks on record and list-entry events, with polling as a fallback. Stacksync manages rate limits, retries, and schema changes automatically.

Is the Attio connector two-way?

Yes. Changes made in Attio 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 an Attio integration take to set up?

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

Is Attio data secure in transit?

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