Sift Python Bindings

Bindings for Sift's APIs -- including the Events, Labels, and Score APIs.

Installation

# install from PyPi
pip install Sift

Documentation

Please see here for the most up-to-date documentation.

Changelog

Please see the CHANGELOG for a history of all changes.

Note, that in v2.0.0, the API semantics were changed to raise an exception in the case of error to be more pythonic. Client code will need to be updated to catch sift.client.ApiException exceptions.

Usage

Here's an example:

import sift

client = sift.Client(api_key='<your API key here>', account_id='<your account ID here>')

# User ID's may only contain a-z, A-Z, 0-9, =, ., -, _, +, @, :, &, ^, %, !, $
user_id = "23056"

# Track a transaction event -- note this is a blocking call
properties = {
    "$user_id": user_id,
    "$user_email": "buyer@gmail.com",
    "$seller_user_id": "2371",
    "seller_user_email": "seller@gmail.com",
    "$transaction_id": "573050",
    "$payment_method": {
        "$payment_type": "$credit_card",

        "$card_bin": "542486",
        "$card_last4": "4444"
    },
    "$currency_code": "USD",
    "$amount": 15230000,
}

try:
    response = client.track(
        "$transaction",
        properties,
    )

    # request failed
    pass

    if response.is_ok():
        print("Successfully tracked event")


# Track a transaсtion event and receive a score with percentiles in response (sync flow).
