GitHub - mixpanel/mixpanel-python: Official Mixpanel Python library.

May 13, 2026 - v5.1.0

PyPI PyPI - Python Version PyPI - Downloads Tests

This is the official Mixpanel Python library. This library allows for server-side integration of Mixpanel.

To import, export, transform, or delete your Mixpanel data, please see our mixpanel-utils package.

Installation

The library can be installed using pip:

Getting Started

Typical usage usually looks like this:

from mixpanel import Mixpanel

mp = Mixpanel(YOUR_TOKEN)

# tracks an event with certain properties
mp.track(DISTINCT_ID, 'button clicked', {'color' : 'blue', 'size': 'large'})

# sends an update to a user profile
mp.people_set(DISTINCT_ID, {'$first_name' : 'Ilya', 'favorite pizza': 'margherita'})

You can use an instance of the Mixpanel class for sending all of your events and people updates.

Service Account Authentication

For enhanced security in server-to-server integrations, you can use service account credentials for authentication instead of API secrets:

from mixpanel import Mixpanel, ServiceAccountCredentials

# Create credentials object
# Service accounts replace api_key/api_secret for authentication
credentials = ServiceAccountCredentials(
    username='YOUR_SERVICE_ACCOUNT_USERNAME',
    secret='YOUR_SERVICE_ACCOUNT_SECRET',
    project_id='YOUR_PROJECT_ID'
)

# Token identifies the project and is used for event tracking
# Credentials are used for endpoints that require authentication
mp = Mixpanel(YOUR_TOKEN, credentials=credentials)

# Event tracking operations use the token (sent in payload)
mp.track(DISTINCT_ID, 'button clicked', {'color': 'blue'})
mp.people_set(DISTINCT_ID, {'$first_name': 'John'})

Service account credentials can also be used with custom consumers like BufferedConsumer:

from mixpanel import Mixpanel, BufferedConsumer, ServiceAccountCredentials

credentials = ServiceAccountCredentials(
    username='YOUR_SERVICE_ACCOUNT_USERNAME',
    secret='YOUR_SERVICE_ACCOUNT_SECRET',
    project_id='YOUR_PROJECT_ID'
)

# Option 1: Pass credentials to the consumer constructor
consumer = BufferedConsumer(max_size=50, credentials=credentials)
mp = Mixpanel(YOUR_TOKEN, consumer=consumer)

# Option 2: Let Mixpanel create the default consumer with credentials
mp = Mixpanel(YOUR_TOKEN, credentials=credentials)

# Event tracking uses the token (sent in payload)
mp.track(DISTINCT_ID, 'event_name')

Service account credentials are only used for the /import endpoint and feature flags. Regular event tracking operations (track, people_set, group_set) use the token provided in the constructor, which is sent in the event payload.

Service Accounts with Feature Flags

Service account credentials are automatically used for feature flag operations when configured:

from mixpanel import Mixpanel, ServiceAccountCredentials
from mixpanel.flags.types import LocalFlagsConfig

credentials = ServiceAccountCredentials(
    username='YOUR_SERVICE_ACCOUNT_USERNAME',
    secret='YOUR_SERVICE_ACCOUNT_SECRET',
    project_id='YOUR_PROJECT_ID'
)

# Token identifies the project for event tracking, credentials handle authentication
mp = Mixpanel(
    YOUR_TOKEN,
    credentials=credentials,
    local_flags_config=LocalFlagsConfig()
)

# Feature flag requests will use service account authentication
variant = mp.local_flags.get_variant_value('my-flag', fallback_value=False, context={...})

Note: When using service account credentials, the token parameter in the Mixpanel constructor is still required for event tracking operations (track, people_set, etc.) since the token is included in the event data payload. However, feature flag operations use the project_id from credentials instead of the token for authentication.
