Emailage Ruby API Client

alt text

The Emailage™ API is organized around REST (Representational State Transfer). The API was built to help 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.


Add this line to your application's Gemfile:

gem 'emailage'

And then execute:


Or install it yourself as:

gem install emailage


Instantiate a client

# For a production server
emailage ='My account SID', 'My auth token')
# ... or for a sandbox
emailage ='My account SID', 'My auth token', sandbox: true)

Query risk score information for the provided email address, IP address, or a combination

# For an email address
emailage.query '[email protected]'
# For an IP address
emailage.query ''
# For a combination. Please note the order
emailage.query ['[email protected]', '']
# Pass a User Defined Record ID.
# Can be used when you want to add an identifier for a query.
# The identifier will be displayed in the result.
emailage.query '[email protected]', urid: 'My record ID for [email protected]'

Explicit methods produce the same request while validating format of the arguments passed

# For an email address
emailage.query_email '[email protected]'
# For an IP address
emailage.query_ip_address ''
# For a combination. Please note the order
emailage.query_email_and_ip_address '[email protected]', ''
# Pass a User Defined Record ID
emailage.query_email_and_ip_address '[email protected]', '', urid: 'My record ID for [email protected] and'

Mark an email address as fraud, good, or neutral. All the listed forms are possible.

When you mark an email as fraud, you must pass the fraudCodeId: 1 - "Card Not Present Fraud" 2 - "Customer Dispute (Chargeback)" 3 - "First Party Fraud" 4 - "First Payment Default" 5 - "Identify Theft (Fraud Application)" 6 - "Identify Theft (Account Take Over)" 7 - "Suspected Fraud (Not Confirmed)" 8 - "Synthetic ID" 9 - "Other"

# Mark an email address as fraud.
emailage.flag 'fraud',   '[email protected]', 8
emailage.flag_as_fraud   '[email protected]', 8
# Mark an email address as good.
emailage.flag 'good',    '[email protected]'
emailage.flag_as_good    '[email protected]'
# Unflag an email address that was previously marked as good or fraud.
emailage.flag 'neutral', '[email protected]'
emailage.remove_flag     '[email protected]'
