Why teams connect Attio and SQL Server

Treat Attio like part of your database: its records live in SQL Server as real tables, and writes in either place sync to the other in seconds.

Teams sync Attio with SQL Server to keep an operational mirror of the CRM inside their own database. Attio People, Companies, and Deals land in SQL Server Tables with proper Schemas and Primary Keys, so engineering and analytics teams can query CRM data with standard SQL — and write back to Attio from the same tables.

Stacksync mirrors Deals, Workspaces, Custom objects, People from Attio into Databases, Schemas, Tables, Views in SQL Server with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Attio with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • 01 Query Attio People and Deals with SQL instead of the Attio API.
  • 02 Enrich Attio Companies from data already stored in SQL Server Tables.
  • 03 Keep Primary and Unique Keys enforced on CRM data for reliable joins with internal systems.
  • 04 Sync companies, people, and deals with Postgres so ops teams enrich and update CRM records with SQL.

Common sync patterns

CRM mirror in SQL Server

Attio People, Companies, and Deals sync into SQL Server Tables under a dedicated Schema, updated bi-directionally.

Database-driven record updates

rows updated in SQL Server Tables propagate back to Attio Companies and Custom objects.

Reporting views on CRM data

SQL Server Views join synced Attio Deals with internal tables for downstream reporting.

What you can sync between Attio and SQL Server

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 SQL Server objects How this pairing syncs
Workspaces Synced with incremental and full sync per the Stacksync docs. Schemas Namespaces (dbo and custom) used to organize synced tables. Workspaces is specific to Attio and Schemas to SQL Server — each maps to any object or custom field on the other side.
Custom objects Workspace-defined objects that behave like standard ones in the API. Tables The primary sync target; rows map to records in connected systems. Custom objects is specific to Attio and Tables to SQL Server — each maps to any object or custom field on the other side.
People Standard person object; synced with marketing tools and warehouse person tables. Views Read-side projections used as outbound sync sources. People is specific to Attio and Views to SQL Server — 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. Columns Field-level mapping targets with T-SQL types. Companies is specific to Attio and Columns to SQL Server — each maps to any object or custom field on the other side.
Users Synced with incremental and full sync per the Stacksync docs. Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Users is specific to Attio and Primary and Unique Keys to SQL Server — 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. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Deals is specific to Attio and CDC Change Tables to SQL Server — each maps to any object or custom field on the other side.

How changes propagate between Attio and SQL Server

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 SQL Server 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 applied to SQL Server as a row-level write, with types converted between the two schemas.

SQL Server Attio Sub-second propagation

DetectionChanges in SQL Server are captured at the source via change data capture — no polling loop against its API. SQL Server Native Change Data Capture (CDC).

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.
  • SQL Server: No API rate limits; throughput depends on instance resources, licensing tier, and connection limits.
