Attio to Twenty CRM integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Attio and Twenty CRM: authenticate both systems, choose the objects to sync (such as Attio's Companies and Users), map fields visually, and changes propagate both ways in milliseconds — no code required.

On the Attio side: Deals, Workspaces, Custom objects, People, plus custom fields where Attio exposes them. On the Twenty CRM side: Custom Objects, Attachments, Workspace Members, People. Stacksync auto-detects both schemas and converts types between the two systems.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Attio and Twenty CRM: Divisional or regional split; Where both track pipeline: deal visibility across systems; Post-acquisition consolidation. Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

Attio: 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). Twenty CRM: GraphQL and REST APIs. Authentication: API key. Stacksync manages authentication, retries, and rate limits on both sides.

Attio: Records are distinct from list entries; the same company can appear in multiple lists with list-specific attribute values, which a faithful sync replicates separately. Twenty CRM: Both GraphQL and REST APIs are generated from the workspace's object schema, so custom objects get the same API surface as standard ones. Stacksync's field mapping accounts for these differences between Attio and Twenty CRM without custom code.
