The Python-language Emailage™ API client helps companies integrate with our highly efficient fraud risk and scoring system. By calling our API endpoints and simply passing us an email and/or IP Address, companies will be provided with real-time risk scoring assessments based around machine learning and proprietary algorithms that evolve with new fraud trends.
- Python 2.7+ or 3.3+
The Emailage client can be installed with pip:
$ pip install emailage-official
or directly from the source code:
$ git clone https://github.com/emailage/Emailage_Python.git
$ cd Emailage_Python
$ python setup.py install
from emailage.client import EmailageClient
client = EmailageClient('My account SID', 'My auth token')
from emailage.client import EmailageClient
client = EmailageClient('My account SID', 'My auth token', sandbox=True)
from emailage.client import EmailageClient
client = EmailageClient('My account SID', 'My auth token', sandbox=True)
# For an email address
client.query('test@example.com')
# For an IP address
client.query('127.0.0.1')
# For a combination. Please note the order
client.query(('test@example.com', '127.0.0.1'))
# Pass a User Defined Record ID (URID).
# Can be used when you want to add an identifier for a query.
# The identifier will be displayed in the result.
client.query('test@example.com', urid='My record ID for test@example.com')
Explicit methods produce the same request while validating format of the arguments passed
from emailage.client import EmailageClient
client = EmailageClient('My account SID', 'My auth token', sandbox=True)
# For an email address
client.query_email('test@example.com')
# For an IP address
client.query_ip_address('127.0.0.1')
# For a combination. Please note the order
client.query_email_and_ip_address('test@example.com', '127.0.0.1')
# Pass a User Defined Record ID
client.query_email_and_ip_address('test@example.com', '127.0.0.1', urid='My record ID for test@example.com and 127.0.0.1')
You may report that you have found that an email address is good, is associated with fraud, or is neither (neutral).
The call to flag an email address as fraud must be accompanied by one of the fraud reasons enumerated below:
- Card Not Present Fraud
- Customer Dispute (Chargeback)
- First Party Fraud
- First Payment Default
- Identify Theft (Fraud Application)
- Identify Theft (Account Take Over)
- Suspected Fraud (Not Confirmed)
- Synthetic ID
- Other
from emailage.client import EmailageClient
client = EmailageClient('My account SID', 'My auth token', sandbox=True)
client.flag('fraud', 'test@example.com', 8)
client.flag_as_fraud('test@example.com', 8)
# Mark an email address as good
client.flag('good', 'test@example.com')
client.flag_as_good('test@example.com')
# Unflag an email address that was previously marked as good or fraud
client.flag('neutral', 'test@example.com')
client.remove_flag('test@example.com')
This client can throw exceptions on any of the following issues:
- When Requests has an issue, like not being able to connect from your server to the Emailage API,
- When incorrectly-formatted JSON is received,
- When an incorrectly-formatted email or IP address is passed to a flagging or explicit querying method.
