Segment

Common Integration Patterns

• → Write Once, Send Everywhere: The core pattern is instrumenting your app with Segment code once, then switching on destinations (GA4, Mixpanel, Facebook Pixel) in the dashboard.
• → Identity Resolution: Stitches together anonymous browsing history with identified user behavior once a user signs up/logs in.
• → Warehouse Loading: Automatically pipes all raw event data into a data warehouse (Snowflake, BigQuery, Redshift) for SQL analysis.

Integration Challenges

• ⚠ Event Naming Chaos: If developers don't stick to a strict 'Object Action' naming convention (e.g., 'Order Completed'), downstream tools will receive messy, unusable data.
• ⚠ PII Leaks: Accidentally passing PII (Personally Identifiable Information) in track calls can violate GDPR/CCPA compliance when that data hits downstream tools.
• ⚠ Debugging: It can be difficult to tell if a data discrepancy is caused by the Segment implementation or the destination tool's processing logic.

Before You Integrate

1. 1. Create a Tracking Plan: Document every event, property, and data type in a shared sheet before writing a single line of code.
2. 2. Configure Privacy Filters: Use Segment's privacy controls to block PII from being sent to destinations that shouldn't receive it.
3. 3. Implement 'identify' Call: Ensure the Identify call is made immediately upon login to link anonymous and known sessions.
4. 4. Verify Destination Settings: Check the specific settings for each enabled destination (e.g., connection modes: Cloud vs. Device) to understand data latency.
