Why teams connect Apollo.io and Azure Cosmos DB

Treat Apollo.io 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 People (database records), Sequences, Deals (Opportunities), Tasks and calls from Apollo.io into Containers, Items (JSON documents), Partition keys, Change feed entries 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 Apollo.io 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

  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • 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.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Azure Cosmos DB sync onto the matching records in Apollo.io, 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 Apollo.io API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Apollo.io arrive as row changes in Azure Cosmos DB, ready to drive jobs and notifications.

What you can sync between Apollo.io and Azure Cosmos DB

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.

Apollo.io objects Azure Cosmos DB objects
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Partition keys Determine data distribution and must be included on writes for the sync to route items correctly.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Databases Top-level namespaces that scope containers and throughput provisioning.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Containers The unit of partitioning and throughput; each container maps to a synced collection.

How the Apollo.io and Azure Cosmos DB connectors work

Apollo.io

Integration surface
REST API
Authentication
API key (passed in request headers); master keys unlock account-wide endpoints
Change detection
Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream
Capabilities
read · write
Rate limits
Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls

Azure Cosmos DB

Integration surface
REST API and SDKs over HTTPS (API for NoSQL, formerly the SQL API); also MongoDB, Cassandra, Gremlin, and Table API surfaces
Authentication
Account keys, resource tokens, or Microsoft Entra ID role-based access
Change detection
Built-in change feed exposing inserts and updates in order within each partition key range
Capabilities
