Why teams connect Azure SQL Database and Close

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

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in Azure SQL Database, where it can be queried and joined like everything else.

Stacksync mirrors Custom Fields, Users, Smart Views, Leads from Close into Rows and columns, Stored procedures, Change tracking / CDC tables, Tables in Azure SQL Database with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Close 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

  • Write product usage or firmographic data from an internal database onto Close lead custom fields to prioritize follow-up.
  • Sync Close leads and opportunities into Postgres or a warehouse for pipeline reporting outside Close's built-in reports.
  • Consolidate data from several line-of-business apps into one Azure SQL database as an integration hub.
  • Feed an Azure SQL operational database with orders and inventory from an ERP in near real time.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Close API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Close arrive as row changes in Azure SQL Database, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Close become tables in Azure SQL Database you can join with application data directly.

What you can sync between Azure SQL Database and Close

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.

Azure SQL Database objects Close objects
Change tracking / CDC tables System-maintained change records used to drive incremental sync. Custom Activities User-defined activity types with their own custom fields, mapped like standard activities.
Tables The primary sync target; rows map one-to-one to records in the paired system. Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs.
Views Read-only projections used when the sync should expose a curated shape rather than raw tables. Users Sales reps referenced as owners on leads, opportunities, and activities.
Schemas Namespaces that organize tables and control which objects a sync user can reach. Smart Views Saved lead searches that can scope which records a segment-based sync pulls.
Rows and columns Standard relational records with typed columns; primary keys anchor upserts. Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history.
Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts. Contacts People nested under a lead, with emails and phone numbers used for outreach syncs.
