Why teams connect Affinity and MySQL

Treat Affinity 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 Reminders, Lists, List Entries, Persons from Affinity 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 Affinity 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 Push enrichment data computed elsewhere into Affinity field values on list entries.
  • 02 Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • 03 Keep e-commerce orders in MySQL flowing into finance and fulfillment systems without export scripts
  • 04 Feed a warehouse from MySQL continuously using binlog-based capture instead of nightly dumps

Common sync patterns

Query the CRM like a database

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

What you can sync between Affinity 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.

Affinity objects MySQL objects How this pairing syncs
Organizations Company records matched to accounts in other systems by domain. JSON Columns Validated semi-structured payloads for nested SaaS data. Organizations is specific to Affinity and JSON Columns to MySQL — each maps to any object or custom field on the other side.
Opportunities Deal records tracked on lists and synced with pipeline reporting. Stored Procedures Server-side logic that can post-process synced rows. Opportunities is specific to Affinity and Stored Procedures to MySQL — each maps to any object or custom field on the other side.
Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. Triggers An alternative change-capture mechanism when binlog access is unavailable. Field Values is specific to Affinity and Triggers to MySQL — each maps to any object or custom field on the other side.
Notes Meeting and call notes synced for record-keeping in other systems. Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. Notes is specific to Affinity and Databases (Schemas) to MySQL — each maps to any object or custom field on the other side.
Interactions Automatically captured emails and meetings, read for activity reporting. Tables The primary sync target; rows map to records in connected systems. Interactions is specific to Affinity and Tables to MySQL — each maps to any object or custom field on the other side.
Reminders Follow-up tasks associated with people and organizations. Views Read-side projections used as outbound sync sources. Reminders is specific to Affinity and Views to MySQL — each maps to any object or custom field on the other side.

How changes propagate between Affinity and MySQL

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.

Affinity MySQL Sub-second propagation

DetectionAffinity notifies Stacksync of record changes through webhook events. Webhook subscriptions for record events, supplemented by polling.

DeliveryEach detected change is applied to MySQL as a row-level write, with types converted between the two schemas.

MySQL Affinity Sub-second propagation

DetectionChanges in MySQL are captured at the source via change data capture — no polling loop against its API. Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when.

DeliveryEach detected change is written to Affinity through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Affinity: Subject to the platform's published API rate limits.
  • MySQL: No API rate limits; throughput is bounded by connection limits and server resources.
