Two-way sync between enterprise systems & databases at any scale

The Complete Architectural Guide

Two-way sync with data event and workflow automation

Two-way sync between Salesforce and Postgres, with data event capture to trigger a workflow automation tool.

While two-way syncs handle data movement as well as data access and manipulation, real-world business processes often require more sophisticated event handling. Consider a scenario where a customer's email address changes. This single update might trigger a cascade of important business processes: validating the new email address, notifying the old address of the change, updating multiple systems of record, and maintaining a comprehensive audit trail.

Here's how this works in practice: when a contact's email changes, the sync system detects this specific field-level change. This triggers a workflow that orchestrates multiple actions:

  1. A validation email is sent to the new address to verify its accuracy
  2. A notification is sent to the old email address as a security measure
  3. The event is logged across multiple systems - the CRM for sales visibility, customer success tools for support context, and the Snowflake data warehouse for analytics and compliance

Stacksync workflows are designed to handle these complex, mission-critical processes at enterprise scale. The system processes tens of millions of workflow executions per minute, making it suitable for both customer data management in CRM systems and high-volume transactional data in ERP systems, such as real-time parcel tracking.

The key advantage of this approach is that it maintains data consistency across all systems while orchestrating complex business logic. Each step in the workflow is monitored, logged, and can be retried if necessary, ensuring that critical business processes remain reliable even at massive scale.

Use cases:

  1. Real-time email validation
  2. Data health check for data quality monitoring and alerting
  3. Real-time customer engagement and outreach
  4. Sales process automation
  5. ERP parcel tracking and CRM follow-up integration
  6. Logging and monitoring all changes happening in systems (CDC - Change Data Capture)
  7. Avoid vendor lock-in with CRM’s sub-par integrated flow tool
