Two-way sync
Changes in Attio or Salesforce instantly reflect in both systems. No stale data, no manual imports.
Keep Attio and Salesforce in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.
Stacksync syncs Workspaces, Custom objects, People, Companies in Attio with Contacts, Leads, Opportunities, Cases in Salesforce in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.
Deal stage and value on shared accounts stay visible from either CRM.
Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.
When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Attio objects | Salesforce objects | |
|---|---|---|
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Tasks and Events Activity records; usually read-only in syncs to feed activity reporting. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Products and Price Books Catalog and pricing data; commonly mastered in an ERP and written into Salesforce. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Custom Objects Org-specific tables with the __c suffix; discoverable via describe metadata so field mappings can be generated. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP. | |
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Attio–Salesforce connection.
Changes in Attio or Salesforce instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Attio or Salesforce data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Attio or Salesforce record.
Track your Attio ⇄ Salesforce sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Attio and Salesforce.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Attio and Salesforce with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Attio and Salesforce objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Attio and Salesforce: 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.
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 Salesforce: Where both track pipeline: deal visibility across systems; Post-acquisition consolidation; Migration with a parallel run. Deal stage and value on shared accounts stay visible from either CRM.
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). Salesforce: REST, SOAP, and Bulk APIs. Authentication: OAuth login via a Salesforce user (browser-based authorization flow); requires "API Enabled" permission for polling mode, plus "Author Apex" and "Customize Application" OR "Modify All Data" for trigger mode. Stacksync manages authentication, retries, and rate limits on both sides.
Attio: Docs do not document the authentication mechanism, change-detection method, or write/CDC/webhook behavior for Attio. Salesforce: Records are queried with SOQL, and every standard and custom object carries a SystemModstamp field that sync engines use to order incremental changes. Stacksync's field mapping accounts for these differences between Attio and Salesforce 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 Salesforce records are not retained after a sync operation.
