POST https://api2.amplitude.com/2/httpapi

{
  "api_key": "{api_key}",
  "events": [{
    "user_id": "user_123",
    "event_type": "signup_completed",
    "event_properties": {
      "plan": "pro"
    },
    "user_properties": {
      "email": "user@example.com"
    }
  }]
}

Batch events

POST https://api2.amplitude.com/batch

{
  "api_key": "{api_key}",
  "events": [
    {"user_id": "user_1", "event_type": "pageview"},
    {"user_id": "user_2", "event_type": "signup"}
  ]
}

Get user activity

GET https://amplitude.com/api/2/useractivity?user={user_id}

Authorization: Basic {base64(api_key:secret_key)}

Export events

GET https://amplitude.com/api/2/export?start=20240101T00&end=20240131T23

Authorization: Basic {base64(api_key:secret_key)}

Query with SQL (Snowflake)

For Amplitude customers with SQL access:

SELECT event_type, COUNT(*) as count
FROM events
WHERE event_time > '2024-01-01'
GROUP BY event_type

JavaScript SDK

// Initialize
amplitude.init('API_KEY');

// Identify user
amplitude.setUserId('user_123');

// Set user properties
const identify = new amplitude.Identify();
identify.set('plan', 'pro');
amplitude.identify(identify);

// Track event
amplitude.track('Feature Used', {
  feature_name: 'export'
});

Key Concepts

• Events - User actions with properties
• User Properties - Persistent user attributes
• Cohorts - Behavioral segments
• Funnels - Multi-step conversion analysis
• Retention - User return patterns
• Journeys - User path analysis

When to Use

• Tracking product analytics
• Analyzing user funnels
• Cohort analysis and retention
• Experimentation and A/B testing
• User journey mapping

Rate Limits

• HTTP API: 1000 events/second
• Export API: 360 requests/hour
