Authsignal Server Ruby SDK

Check out our official Ruby SDK documentation, and Ruby on Rails Quickstart Guide.

Installation

Add this line to your application's Gemfile:

gem "authsignal-ruby"

And then execute:

$ bundle install

Or install it yourself as:

$ gem install authsignal-ruby

Initialization

Initialize the Authsignal Ruby SDK, ensuring you do not hard code the Authsignal Secret Key, always keep this safe.

In Ruby on Rails, you would typically place this code block in a file like config/initializers/authsignal.rb

Authsignal.setup do |config|
    config.api_secret_key = ENV["AUTHSIGNAL_SECRET_KEY"]
end

You can find your api_secret_key in the Authsignal Portal.

You must specify the correct baseUrl for your tenant's region.

Region	Base URL
US (Oregon)	https://signal.authsignal.com/v1
AU (Sydney)	https://au.signal.authsignal.com/v1
EU (Dublin)	https://eu.signal.authsignal.com/v1

For example, to set the base URL to use our AU region:

require 'authsignal'

Authsignal.setup do |config|
    config.api_secret_key = ENV["AUTHSIGNAL_SECRET_KEY"]
    config.base_uri = "https://au.signal.authsignal.com/v1"

    # If you would like the Authsignal client to retry requests due to network issues
    config.retry = true # default value: false

    # If you would like to inspect raw request/response in development
    config.debug = true # default value: false
end

Usage

Authsignal's server side signal API has four main api calls track, get_action, get_user, enroll_verified_authenticator.

For more details on these api calls, refer to our official Ruby SDK docs.

Example:

Authsignal.track user_id: 'AS_001', action: 'withdraw', idempotency_key: 'a_random_hash'

# returns:
# {
#    success?: true,
#    state: 'ALLOW',
#    idempotency_key: 'a_random_hash',
#    ... rest of payload ...
# }

Response & Error handling

The Authsignal SDK offers two response formats. By default, its methods return the payload in hash format.

Example:

Authsignal.enroll_verified_authenticator user_id: 'AS_001',
                                         authenticator: {
                                           oob_channel: 'INVALID', email: 'joebloke@authsignal.com'
                                         }

# returns:
# {
#    success?: false,
#    status: 400,
#    error: 'invalid_request',
#    error_description: '/body/oobChannel must be equal to one of the allowed values'
# }

All methods have a bang (!) counterpart that raises an Authsignal::ApiError if the request fails.

Example:

Authsignal.enroll_verified_authenticator! user_id: 'AS_001',
                                         authenticator: {
                                           oob_channel: 'INVALID', email: 'joebloke@authsignal.com'
                                         }

# raise:
# <Authsignal::ApiError: invalid_request status: 400, error: invalid_request, description: /body/oobChannel must be equal to one o...

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec or bundle exec rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

Log request/response against test server: Authsignal.configuration.debug = true
