What this integration does
The Allo-Attio integration keeps your CRM up to date automatically. Every call syncs to Attio as a note with recordings and AI summaries. Perfect for teams using Attio’s modern CRM to manage customer relationships. Key benefits:- Automatic contact sync between Allo and Attio
- Call enrichment with Attio data during calls
- Call recordings and summaries logged as notes
- Real-time two-way data sync
Attio doesn’t have native “Call” objects, so Allo logs calls as notes in contact profiles.
