Why teams connect Apollo.io and InterSystems IRIS

Treat Apollo.io like part of your database: its records live in InterSystems IRIS 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 InterSystems IRIS, where it can be queried and joined like everything else.

Stacksync mirrors Custom fields, Contacts, Accounts, People (database records) from Apollo.io into Schemas, Persistent Classes, Globals, Namespaces in InterSystems IRIS 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.
  • Keep reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools
  • Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing

Trigger workflows from CRM changes

Field and stage updates in Apollo.io arrive as row changes in InterSystems IRIS, ready to drive jobs and notifications.

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to InterSystems IRIS sync onto the matching records in Apollo.io, giving go-to-market teams live product context.

What you can sync between Apollo.io and InterSystems IRIS

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 InterSystems IRIS objects
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Schemas Schema organization scopes which tables a sync connection can see.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Persistent Classes Object-model classes project to tables, so class data is reachable through SQL.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Globals The underlying multidimensional storage; typically accessed indirectly via SQL or objects in syncs.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Namespaces Namespaces partition databases and determine the connection context for integrations.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Stored Procedures Server-side logic callable over SQL supports controlled writes and transformations.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Tables Relational projections of stored data are the primary read/write surface for SQL-based syncs.

How the Apollo.io and InterSystems IRIS 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

InterSystems IRIS

Integration surface
SQL over JDBC/ODBC, plus object and REST access layers
Authentication
Database credentials
Change detection
Polling (timestamp or query-based); no standard webhook surface
Capabilities
read · write
Rate limits
Constrained by database resources rather than published API rate limits
