Why teams connect Apollo.io and SingleStore

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

Stacksync mirrors Accounts, People (database records), Sequences, Deals (Opportunities) from Apollo.io into Reference Tables, Pipelines, Stored Procedures, Indexes and Shard Keys in SingleStore 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 CRM and SaaS objects into SingleStore tables to serve low-latency operational dashboards.
  • Sync results of real-time analytical queries back into business tools where teams act on them.

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to SingleStore 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 SingleStore

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 SingleStore objects
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Views Read-only projections used as curated sync sources.
Tasks and calls Rep activity records synced for activity reporting and coaching workflows. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Stored Procedures Existing logic sometimes invoked on write paths.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Indexes and Shard Keys Determine data distribution and lookup speed for sync match keys.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Databases The connection target containing the tables a sync addresses.

How the Apollo.io and SingleStore 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

SingleStore

Integration surface
SQL over the MySQL wire protocol; an HTTP Data API is also available for SQL over REST
Authentication
Database credentials
Change detection
Polling on timestamp or watermark columns; the platform also provides change-observation features in recent versions
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by workspace or cluster size
