Why teams connect Kustomer and MySQL

Treat Kustomer 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 Customers, Conversations, Messages, Companies from Kustomer into Databases (Schemas), Tables, Views, Columns in MySQL with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Kustomer 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

  • Escalate conversation-derived signals into the CRM as tasks or opportunities
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Feed a warehouse from MySQL continuously using binlog-based capture instead of nightly dumps
  • Two-way sync between a MySQL application database and a CRM so operational records and sales records stay identical

Query the CRM like a database

Accounts, contacts, and custom objects from Kustomer 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 Kustomer, 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 Kustomer API, limits, and retries.

What you can sync between Kustomer 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.

Kustomer objects MySQL objects
Users Agent records map conversation ownership to people in other systems. Views Read-side projections used as outbound sync sources.
Teams Team assignments support routing parity and reporting. Columns Field-level mapping targets with engine-typed values.
Tags Labels on conversations and customers sync for categorization and analytics. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Notes Internal annotations carry context alongside synced conversations. JSON Columns Validated semi-structured payloads for nested SaaS data.
Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Stored Procedures Server-side logic that can post-process synced rows.
Conversations Support threads across channels sync outward for analytics and CRM context. Triggers An alternative change-capture mechanism when binlog access is unavailable.
