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": "[e-mail]",
    "$seller_user_id": "2371",
    "seller_user_email": "[e-mail]",
    "$transaction_id": "573050",
    "$payment_method": {
        "$payment_type": "$credit_card",
        "$payment_gateway": "$braintree",
        "$card_bin": "542486",
        "$card_last4": "4444"
    },
    "$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

# Request a score for the user with user_id 23056
try:
    response = client.score(user_id)
    s = json.dumps(response.body)
    print s

except sift.client.ApiException:
    # request failed
    pass

try:
    # Label the user with user_id 23056 as Bad with all optional fields
    response = client.label(user_id, {
        "$is_bad": True,
        "$abuse_type": "payment_abuse",
        "$description": "Chargeback issued",
        "$source": "Manual Review",
        "$analyst": "analyst.name@your_domain.com"
    })
except sift.client.ApiException:
    # request failed
    pass

# Remove a label from a user with user_id 23056
try:
    response = client.unlabel(user_id, abuse_type='content_abuse')
except sift.client.ApiException:
    # request failed
    pass

# Get the status of a workflow run
try:
    response = client.get_workflow_status('my_run_id')
except sift.client.ApiException:
    # request failed
    pass

# Get the latest decisions for a user
try:
    response = client.get_user_decisions('example_user')
except sift.client.ApiException:
    # request failed
    pass

# Get the latest decisions for an order
try:
    response = client.get_order_decisions('example_order')
except sift.client.ApiException:
    # request failed
    pass

# Get the latest decisions for a session
try:
    response = client.get_session_decisions('example_user', 'example_session')
except sift.client.ApiException:
    # request failed
    pass

# Get the latest decisions for a piece of content
try:
    response = client.get_content_decisions('example_user', 'example_content')
except sift.client.ApiException:
    # request failed
    pass

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

5.2.0 2022-11-07

• Update PSP Merchant Management API

5.1.0 2022-06-22

• Added return_route_info query parameter
• Fixed decimal amount json serialization bug

5.0.2 2022-01-24

5.0.0 2019-01-08

• Add connection pooling

INCOMPATIBLE CHANGES INTRODUCED IN 5.0.0:

• Removed support for Python 2.6

• Fix url encoding for all endpoints

  Previously, encoding user ids in URLs was inconsistent between endpoints, encoded for some endpoints, unencoded for others. Additionally, when encoded in the URL path, forward slashes weren't encoded. Callers with workarounds for this bug must remove these workarounds when upgrading to 5.0.0.

• Improved error handling

  Previously, illegal arguments passed to methods like Client.track() and failed calls resulting from server-side errors both raised ApiExceptions. Illegal arguments validated in the client now raise either TypeErrors or ValueErrors. Server-side errors still raise ApiExceptions, and ApiException has been augmented with metadata for handling the error.

4.3.0.0 2018-07-31

• Add support for rescore_user and get_user_score APIs

4.2.0.0 2018-07-05

4.0.0.0 2018-03-30

• Adds support for Sift Science API Version 205, including new $create_content and $update_content formats
• V205 APIs are now called -- this is an incompatible change
  • Use version = '204' when constructing the Client to call the previous API version
• Adds support for content decisions to Decisions API

INCOMPATIBLE CHANGES INTRODUCED IN API V205:

• $create_content and $update_content have significantly changed, and the old format will be rejected
• $send_message and $submit_review events are no longer valid
• V205 improves server-side event data validation. In V204 and earlier, server-side validation accepted some events that did not conform to the published APIs in our developer documentation. V205 does not modify existing event APIs other than those mentioned above, but may reject invalid event data that were previously accepted. Please test your integration on V205 in sandbox before using in production.
