Attio to Postgres Heroku integration — real-time, two-way sync

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

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 Postgres Heroku: Query the CRM like a database; Product events onto CRM records; Internal tools without API code. Accounts, contacts, and custom objects from Attio become tables in Postgres Heroku you can join with application data directly.

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). Postgres Heroku: SQL wire protocol (standard PostgreSQL). Authentication: Database credentials from the Heroku DATABASE_URL config var; SSL required. Stacksync manages authentication, retries, and rate limits on both sides.

Attio: Object coverage limited to the six listed entries (People, Companies, Users, Deals, Workspaces, custom objects); anything else requires emailing Stacksync. Postgres Heroku: All connections require SSL, and server-level settings such as replication configuration are controlled by Heroku rather than the user. Stacksync's field mapping accounts for these differences between Attio and Postgres Heroku without custom code.

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Attio and Postgres Heroku records are not retained after a sync operation.
