Why teams connect Apollo.io and VoltDB

Treat Apollo.io like part of your database: its records live in VoltDB 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 VoltDB, 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 Materialized Views, Streams, Export Targets and Topics, Partitioned Tables in VoltDB 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

  • Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.
  • Push aggregates from VoltDB materialized views into dashboards or operational tools.

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to VoltDB 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.

What you can sync between Apollo.io and VoltDB

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 VoltDB objects
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Stored Procedures Precompiled transactional units that serve as the primary write interface.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Streams Insert-only constructs that feed the export subsystem with committed rows.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target.

How the Apollo.io and VoltDB 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

VoltDB

Integration surface
SQL over JDBC plus native client libraries and an HTTP/JSON interface
Authentication
Database credentials
Change detection
Export streams and topics push committed changes to configured targets; otherwise polling
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by partition count and cluster sizing.
