Why teams connect Apollo.io and Azure SQL Database

Treat Apollo.io 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 Deals (Opportunities), Tasks and calls, Custom fields, Contacts from Apollo.io into Tables, Views, Schemas, Rows and columns 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 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

  • Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Expose SaaS data (billing, support tickets) as tables in Azure SQL for reporting teams already on Microsoft tooling.
  • Replicate Azure SQL tables to a warehouse without building custom CDC pipelines.

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 SQL Database, ready to drive jobs and notifications.

Query the CRM like a database

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

What you can sync between Apollo.io and Azure SQL Database

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 SQL Database objects
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Change tracking / CDC tables System-maintained change records used to drive incremental sync.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Tables The primary sync target; rows map one-to-one to records in the paired system.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Views Read-only projections used when the sync should expose a curated shape rather than raw tables.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Schemas Namespaces that organize tables and control which objects a sync user can reach.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Rows and columns Standard relational records with typed columns; primary keys anchor upserts.

How the Apollo.io and Azure SQL Database 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 SQL Database

Integration surface
SQL wire protocol (TDS), the same protocol as SQL Server; T-SQL over standard drivers
Authentication
SQL authentication (database credentials) or Microsoft Entra ID authentication
Change detection
Change data capture or change tracking, both supported on Azure SQL Database; polling as a fallback
Capabilities
read · write · CDC
