Why teams connect Apollo.io and MySQL

Treat Apollo.io like part of your database: its records live in MySQL 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 MySQL, 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 Stored Procedures, Triggers, Databases (Schemas), Tables in MySQL 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.
  • Two-way sync between a MySQL application database and a CRM so operational records and sales records stay identical
  • Expose SaaS objects as MySQL tables so legacy internal tools built on MySQL can read live business data

Trigger workflows from CRM changes

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

Query the CRM like a database

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

Product events onto CRM records

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

What you can sync between Apollo.io and MySQL

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 MySQL objects
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Views Read-side projections used as outbound sync sources.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Columns Field-level mapping targets with engine-typed values.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. JSON Columns Validated semi-structured payloads for nested SaaS data.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Stored Procedures Server-side logic that can post-process synced rows.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Triggers An alternative change-capture mechanism when binlog access is unavailable.

At scale

Event queues

Handle millions of events per minute without losing a single Apollo.io or MySQL record.

Observability

Monitoring

Track your Apollo.io ⇄ MySQL sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between Apollo.io and MySQL.

How the Apollo.io and MySQL 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

MySQL

Integration surface
SQL wire protocol (MySQL client/server protocol)
Authentication
Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host)
Change detection
Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when binary logging is enabled)
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits and server resources
