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
- 01 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
- 02 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.
- 03 Keep reference data consistent between an IRIS-based clinical or financial application and downstream SaaS tools
- 04 Write enriched or corrected records from SaaS apps back into IRIS tables for on-platform processing
Common sync patterns
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 | How this pairing syncs | |
|---|---|---|---|
| Tasks and calls Rep activity records synced for activity reporting and coaching workflows. | Schemas Schema organization scopes which tables a sync connection can see. | Tasks and calls is specific to Apollo.io and Schemas to InterSystems IRIS — each maps to any object or custom field on the other side. | |
| 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. | Custom fields is specific to Apollo.io and Persistent Classes to InterSystems IRIS — each maps to any object or custom field on the other side. | |
| 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. | Contacts is specific to Apollo.io and Globals to InterSystems IRIS — each maps to any object or custom field on the other side. | |
| Accounts Company records with firmographic attributes, matched to CRM accounts during sync. | Namespaces Namespaces partition databases and determine the connection context for integrations. | Accounts is specific to Apollo.io and Namespaces to InterSystems IRIS — each maps to any object or custom field on the other side. | |
| 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. | People (database records) is specific to Apollo.io and Stored Procedures to InterSystems IRIS — each maps to any object or custom field on the other side. | |
| 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. | Sequences is specific to Apollo.io and Tables to InterSystems IRIS — each maps to any object or custom field on the other side. |
How changes propagate between Apollo.io and InterSystems IRIS
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Apollo.io InterSystems IRIS Interval-based propagation
DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.
DeliveryEach detected change is applied to InterSystems IRIS as a row-level write, with types converted between the two schemas.
InterSystems IRIS Apollo.io Interval-based propagation
DetectionStacksync polls InterSystems IRIS for changes on an incremental schedule, reading only records changed since the previous pass. Polling (timestamp or query-based).
DeliveryEach detected change is written to Apollo.io through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
- InterSystems IRIS: Constrained by database resources rather than published API rate limits.

FAQ
Apollo.io and InterSystems IRIS integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and InterSystems IRIS: authenticate both systems, choose the objects to sync (such as Apollo.io's Tasks and calls and Custom fields), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Apollo.io and InterSystems IRIS records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apollo.io and InterSystems IRIS connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apollo.io–InterSystems IRIS integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Apollo.io and InterSystems IRIS. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Apollo.io: Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream. On InterSystems IRIS: Polling (timestamp or query-based); no standard webhook surface. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Apollo.io side: Custom fields, Contacts, Accounts, People (database records), plus custom fields where Apollo.io exposes them. On the InterSystems IRIS side: Schemas, Persistent Classes, Globals, Namespaces. Stacksync auto-detects both schemas and converts types between the two systems.
