Helix by Q2 (ex CorePro) API SDK

Ruby SDK for working with Helix Q2


Add this line to your application's Gemfile:

gem 'core_pro'

And then execute:

$ bundle

Or install it yourself as:

$ gem install core_pro


A subset of the Helix/CorePro resources are provided with this SDK:

  • CorePro::Program
  • CorePro::Customer
  • CorePro::Account
  • CorePro::ExternalAccount
  • CorePro::Transfer
  • CorePro::Transaction

These resources have implemented the following methods to allow API operations:

  • #all
  • #find
  • #create
  • #onboard(kyc_vendor) (only for CorePro::Customer)
  • #by_tag (only for CorePro::Transaction)

Here's an example on how to create a customer, an account, and initiate a transfer:

require 'core_pro'

customer = CorePro::Customer.create(
  firstName: 'James',
  lastName: 'Bond',
  isSubjectToBackupWithholding: false,
  isOptedInToBankCommunication: false,
  isDocumentsAccepted: true


old_account = CorePro::Account.find(customer.customerId, <OLD_ACCOUNT_ID>)

account = CorePro::Account.create(
  customerId: customer.customerId,
  name: 'Test',
  productId: <PRODUCT_ID>

transfer = CorePro::Transfer.create(
  amount: 1.0,
  customerId: customer.customerId,
  fromId: old_account.accountId,
  toId: account.accountId

transactions = CorePro::Transaction.all(
    pageNumber: 0,
    pageSize: 200


The API keys will be loaded from your environment variables:

  • HELIX_ENDPOINT defaults to https://api.helix.q2.com


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 tags, and push the .gem file to rubygems.org.
