Why teams connect Attio and Salesforce
Run Attio and Salesforce side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.
Attio and Salesforce sync when an organization runs both CRMs — a team adopting Attio alongside an entrenched Salesforce org, a migration in progress, or subsidiaries on different systems. Mapping Attio People and Companies to Salesforce Contacts and Accounts, and Attio Deals to Opportunities, keeps both databases consistent so no team works from stale records.
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.
Common use cases
- 01 Run Attio for a fast-moving team while the wider org stays on Salesforce, with one shared account base.
- 02 Migrate from Salesforce to Attio incrementally, keeping Opportunities and Deals reconciled until cutover.
- 03 Surface Salesforce Campaign membership on Attio People to inform outreach without duplicating marketing data.
- 04 Mirror lists and list entries into a database for pipeline reporting beyond the in-app views.
Common sync patterns
Account and contact parity
Salesforce Accounts and Contacts sync bidirectionally with Attio Companies and People, with field-level mapping in both directions.
Opportunity mirroring
Salesforce Opportunities appear as Attio Deals with stage and amount, and edits in either system propagate.
Lead and case context
Salesforce Leads and Cases sync into Attio Custom objects so the Attio team sees inbound interest and support history.
What you can sync between Attio and Salesforce
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 | How this pairing syncs | |
|---|---|---|---|
| Custom objects Workspace-defined objects that behave like standard ones in the API. | Custom Objects Org-specific tables with the __c suffix; discoverable via describe metadata so field mappings can be generated. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| People Standard person object; synced with marketing tools and warehouse person tables. | Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records. | People is specific to Attio and Contacts to Salesforce — each maps to any object or custom field on the other side. | |
| Companies Standard company object; matched to billing and product accounts in two-way syncs. | Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines. | Companies is specific to Attio and Leads to Salesforce — each maps to any object or custom field on the other side. | |
| Users Synced with incremental and full sync per the Stacksync docs. | Opportunities Deal records with stage and amount; synced to databases for pipeline reporting and to ERPs at close. | Users is specific to Attio and Opportunities to Salesforce — each maps to any object or custom field on the other side. | |
| Deals Pipeline records; read out for revenue reporting and written to from automation. | Cases Support records; synced with help desk tools or internal databases for escalation workflows. | Deals is specific to Attio and Cases to Salesforce — each maps to any object or custom field on the other side. | |
| Workspaces Synced with incremental and full sync per the Stacksync docs. | Campaigns Marketing membership data; read out for attribution analysis in the warehouse. | Workspaces is specific to Attio and Campaigns to Salesforce — each maps to any object or custom field on the other side. |
How changes propagate between Attio and Salesforce
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Attio Salesforce Sub-second propagation
DetectionAttio notifies Stacksync of record changes through webhook events. Webhooks on record and list-entry events, with polling as a fallback.
DeliveryEach detected change is written to Salesforce through its API, with automatic retries and rate-limit backoff.
Salesforce Attio Sub-second propagation
DetectionChanges in Salesforce are captured at the source via change data capture — no polling loop against its API. Apex triggers are used whenever possible (Salesforce actively notifies Stacksync via an Apex trigger + callout class + remote site setting).
DeliveryEach detected change is written to Attio through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Attio: Subject to the platform's published API rate limits.
- Salesforce: Daily API request allocations vary by edition and license count.

FAQ
Attio and Salesforce integration FAQ
-
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 Custom objects and People), 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: Account and contact parity; Opportunity mirroring; Lead and case context. Salesforce Accounts and Contacts sync bidirectionally with Attio Companies and People, with field-level mapping in both directions.
-
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.
