OutboundSync → Attio

Attio CRM integration beta

Connect Attio as a Connected Account in OutboundSync and sync one-way email and social activity onto Attio person and company records. Each event writes a Note on the Person, and you can write the same event to an OutboundSync custom object — Attio's model for data that is not a person or company.

What the beta does

A simpler Attio rollout built for activity visibility first

Attio is supported today as a real CRM connection in OutboundSync, but this beta is intentionally lighter than HubSpot and Salesforce. The focus is simple: get outbound activity onto Attio records cleanly, prove the workflow, and expand configurability as the beta matures. OutboundSync is also listed in the Attio App Store — read the App Store announcement for OAuth setup and ecosystem context.

One-way outbound email activity can be synced onto Attio person and company records during the current beta.
One-way outbound social activity can be synced onto Attio person and company records during the current beta.
Optional OutboundSync custom object: one record per event after the Note, so you can filter outbound activity and build Attio lists and views. Enable it on CRM Settings.
Teams can use synced activity inside the Attio lists and views they already build. OutboundSync does not ship prebuilt lists or views for this beta.
Onboarding is handled with the OutboundSync team, not as a self-serve flow.

Attio custom objects

Does OutboundSync support Attio custom objects?

Attio custom objects track data that does not fit People or Companies. OutboundSync writes one locked custom object named OutboundSync — one record per event after the Person Note — so you can filter activity, save views, and run workflows in Attio. Notes still write when it is off. Enable it on CRM Settings.

Custom object records are data you can report on, then group into lists or saved views for a process. Notes stay on the Person. OutboundSync does not ship prebuilt lists or views. It does not write to other custom objects. Setup is in the Attio CRM beta guide. For the walkthrough, see Attio custom objects for outbound activity.

How to enable the OutboundSync custom object in Attio

Create or re-sync the custom object on Attio CRM Settings after Attio is connected.

Connect Attio, then open Attio CRM Settings.
Choose Create custom object, or Re-sync attributes if it already exists. That turns on Write OutboundSync records on webhook events.
Send a test event and confirm the Note on the Person plus one OutboundSync record.

How it maps

Attio activity stays readable for reps and RevOps

The current Attio beta is built around activity capture, not deep bi-directional configuration. That means faster rollout, lower conflict risk, and a simpler beachhead while the integration gets tested in production.
