Best Practices

Keep schemas in sync with your source code:
import json

# Load tracking plan
with open('tracking_plan.json') as f:
    plan = json.load(f)

# Upload to Mixpanel
entries = []
for event in plan['events']:
    entries.append({
        'entityType': 'event',
        'name': event['name'],
        'schema': {
            'description': event['description'],
            'properties': event['properties']
        }
    })

upload_schemas(entries)
Provide context for analysts:
{
  "description": "Fired when user completes checkout and payment is confirmed",
  "properties": {
    "amount": {
      "type": "number",
      "description": "Total purchase amount in USD, including taxes and shipping"
    }
  }
}
Control how properties appear in Mixpanel:
{
  "properties": {
    "user_internal_id": {
      "type": "string",
      "metadata": {
        "com.mixpanel": {
          "hidden": true,
          "displayName": "Internal User ID"
        }
      }
    }
  }
}
