Why teams connect Azure Cosmos DB and Close

Treat Close like part of your database: its records live in Azure Cosmos DB 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 Cosmos DB, where it can be queried and joined like everything else.

Stacksync mirrors Smart Views, Leads, Contacts, Opportunities from Close into Change feed entries, Stored procedures and triggers, Databases, Containers in Azure Cosmos DB 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

  • Sync Close leads and opportunities into Postgres or a warehouse for pipeline reporting outside Close's built-in reports.
  • Two-way sync between Close and a billing or ERP system so closed-won opportunities create customers and invoices automatically.
  • Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.
  • Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to Azure Cosmos DB sync onto the matching records in Close, giving go-to-market teams live product context.

Internal tools without API code

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

What you can sync between Azure Cosmos DB 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 Cosmos DB objects Close objects
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Custom Activities User-defined activity types with their own custom fields, mapped like standard activities.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Custom Fields Org-specific fields on leads, contacts, and opportunities; addressed by stable field ids in syncs.
Databases Top-level namespaces that scope containers and throughput provisioning. Users Sales reps referenced as owners on leads, opportunities, and activities.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Smart Views Saved lead searches that can scope which records a segment-based sync pulls.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Leads The top-level record in Close; represents a company and holds its contacts, opportunities, and activity history.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Contacts People nested under a lead, with emails and phone numbers used for outreach syncs.
