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 json
import sift.client

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",

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

try:
    response = client.track("$transaction", properties)
    if response.is_ok():
        print "Successfully tracked event"
except sift.client.ApiException:
    # request failed
    pass

# Track a transaсtion event and receive a score with percentiles in response (sync flow).
# Note: `return_score` or `return_workflow_status` must be set `True`.

Testing

Before submitting a change, make sure the following commands run without errors from the root dir of the repository:

python -m unittest discover
python3 -m unittest discover

Integration testing app

For testing the app with real calls it is possible to run the integration testing app, it makes calls to almost all our public endpoints to make sure the library integrates well. At the moment, the app is run on every merge to master

How to run it locally

1. Add env variable ACCOUNT_ID with the valid account id
2. Add env variable API_KEY with the valid Api Key associated from the account
3. Run the following under the project root folder

# uninstall the lib from the local env (if it was installed)
pip uninstall sift

# install the lib from the local source code
pip install ../sift-python

# run the app
python test_integration_app/main.py
