Yes, Segment sends events natively to Amplitude, allowing you to stream user interactions and custom events directly into your analytics platform in real-time.
Overview
Segment and Amplitude are complementary tools in the modern analytics stack. Segment acts as your customer data hub—collecting events from websites, mobile apps, and servers—while Amplitude specializes in product analytics, helping you understand user behavior and measure engagement. The native integration between them eliminates manual data pipelines and ensures your analytics team has clean, real-time event data without engineering overhead.
This integration is particularly valuable for product teams, growth managers, and analytics engineers who need to track user journeys across multiple touchpoints and understand what drives retention, conversion, and expansion.
How the Integration Works
- Event Streaming: Segment collects events from your web, mobile, and server-side sources and forwards them to Amplitude in real-time. No batching delays—your analytics dashboard reflects user actions within seconds.
- Unified User Identity: Segment resolves anonymous and identified users, passing a consistent user ID to Amplitude so you can track the full customer journey from first visit through conversion and beyond.
- Custom Event Properties: Any event properties you attach in Segment (e.g., revenue, plan tier, feature flag state) flow directly into Amplitude, enabling rich segmentation and cohort analysis without additional configuration.
- User Traits Sync: Segment’s identify calls—which capture user attributes like email, company, or subscription status—map to Amplitude user properties, allowing you to segment and filter analytics by these dimensions.
- Simple Setup: Enable the Amplitude destination in Segment, paste your Amplitude API key, and configure which events and traits you want to send. No code required for basic use cases.
Key Features & Capabilities
- Real-Time Event Delivery: User actions are sent to Amplitude within seconds, so your product dashboards stay current and you can respond to user behavior trends immediately.
- Cross-Platform Event Tracking: Consolidate events from your website, iOS app, Android app, and backend services into a single Amplitude project, giving you a holistic view of user engagement.
- Automatic User Identification: Segment handles anonymous-to-known user mapping, so Amplitude can stitch together sessions and attribute actions to the right person even before they sign up.
- Event Property Filtering: Choose which event properties to send to Amplitude to reduce noise, control data volume, and keep your analytics clean and focused on what matters.
- Retroactive Cohort Analysis: Once events flow into Amplitude, you can create behavioral cohorts based on any action or property, then use those cohorts for targeting in Segment or other downstream tools.
- No Custom Instrumentation Needed: If you’ve already instrumented Segment, Amplitude gets the same events automatically—you don’t need to duplicate tracking logic.
Setup Difficulty
Easy (5–10 minutes, no code required). Navigate to Segment’s Destinations catalog, search for Amplitude, and enable it. You’ll need your Amplitude API key (found in your Amplitude project settings) and optionally your Amplitude secret key for advanced features. Segment provides a simple form to paste these credentials and select which events to forward. For most teams, the default settings work out of the box.
Common Setup Considerations
- API Key vs. Secret Key: The API key is required; the secret key is optional but enables features like user property updates. Check your Amplitude project settings to locate both.
- Event Filtering: By default, Segment sends all events to Amplitude. If you want to exclude certain events to reduce costs or clutter, you can configure filters in the destination settings.
- User ID Mapping: Ensure your Segment user IDs align with how you identify users in Amplitude. Segment typically uses your internal user ID; confirm Amplitude is configured to accept the same identifier.
- Batch vs. Real-Time: Segment sends events to Amplitude in real-time by default. If you need batching for cost or compliance reasons, this can be adjusted in the destination configuration.
Alternatives & Workarounds
If the native Segment-to-Amplitude integration doesn’t fully meet your needs, consider these options:
- Zapier or Make: Use a workflow automation platform to trigger actions in Amplitude based on Segment events. This adds latency but can be useful for specific, low-volume use cases.
- Custom API Integration: If you need advanced data transformation or conditional routing, your engineering team can build a custom webhook receiver that processes Segment events and sends them to Amplitude’s HTTP API with custom logic.
- Alternative Analytics Platforms: If Amplitude’s feature set doesn’t align with your needs, Segment also integrates natively with Mixpanel, Heap, and Rudderstack, each with different strengths in cohort analysis, session replay, or data warehouse integration.
Frequently Asked Questions
Does Segment send historical data to Amplitude when I enable the integration?
No. The integration begins forwarding events from the moment you enable it in Segment. Historical events already in Segment are not retroactively sent to Amplitude. If you need historical data in Amplitude, you may need to use Amplitude’s data import API or work with your data team to backfill events from your data warehouse.
Can I control which events Segment sends to Amplitude?
Yes. In the Segment destination settings for Amplitude, you can enable or disable specific events. This is useful if you want to reduce data volume, avoid sending sensitive events, or keep your Amplitude project focused on product metrics rather than internal operational events.
What happens if my Amplitude API key is invalid or expires?
Segment will log delivery errors and may pause sending events after repeated failures. You’ll receive notifications in your Segment dashboard. Simply update the API key in the destination settings to resume event flow. Amplitude API keys don’t expire, but if you rotate them for security, you’ll need to update Segment immediately.
Does the integration support user property updates, or only events?
The integration supports both. Segment’s identify calls (which set user traits like email, plan tier, or company) are sent to Amplitude as user properties. This allows you to segment and filter users in Amplitude based on their attributes, not just their actions.
Disclaimer
Integration features and capabilities may change as Segment and Amplitude release updates. This guide reflects the current state of the native integration, but we recommend verifying the latest details on Segment’s official integration documentation and Amplitude’s developer resources before implementing in production.
