Prerequisites

Adyen test account
API key. For testing, your API credential needs to have the API PCI Payments role.
Ruby >= 2.7

Installation

The sole dependency is faraday for HTTP communication. Run the following command to install faraday if you don't already have it:

bundle install

To validate functionality of client and run mock API tests use

bundle install --with development

and

rspec

Documentation

Follow the rest of our guides from the documentation on how to use this library.

Using the library

General use with API key

require 'adyen-ruby-api-library'

adyen = Adyen::Client.new

adyen.api_key = 'AF5XXXXXXXXXXXXXXXXXXXX'

Make a Payment

response = adyen.checkout.payments_api.payments({
  :amount => {
    :currency => "EUR",
    :value => 1000
  },
  :reference => "Your order number",
  :paymentMethod => {
    :type => "scheme",
    :encryptedCardNumber => "test_4111111111111111",
    :encryptedExpiryMonth => "test_03",
    :encryptedExpiryYear => "test_2030",
    :encryptedSecurityCode => "test_737"
  },
  :returnUrl => "https://your-company.com/checkout/",
  :merchantAccount => "YourMerchantAccount"
})

Change API Version

adyen.checkout.version = 69

Running the tests

To run the tests use :

bundle install --with development

Using the Cloud Terminal API Integration

In order to submit In-Person requests with Terminal API over Cloud you need to initialize the client in the same way as explained above for Ecommerce transactions:

# Step 1: Require the parts of the module you want to use
require 'adyen-ruby-api-library'

# Step 2: Initialize the client object
adyen = Adyen::Client.new(api_key: 'YOUR_API_KEY', env: :test)

# Step 3: Create the request
serviceID = "123456789"
saleID = "POS-SystemID12345"
POIID = "Your Device Name(eg V400m-123456789)"

# Use a unique transaction for every transaction you perform
transactionID = "TransactionID"

request = 
{
  "SaleToPOIRequest": {
    "MessageHeader": {
      "MessageClass": "Service",
      "MessageCategory": "Payment",
      "MessageType": "Request",
      "ServiceID": serviceID,
      "SaleID": saleID,
      "POIID": POIID,
      "ProtocolVersion": "3.0"
    },
    "PaymentRequest": {
      "SaleData": {
        "SaleTransactionID": {
          "TransactionID": transactionID,
          "TimeStamp": "2023-08-23T09:48:55"
        },
        "SaleToAcquirerData": "eyJhcHBsaWNhdGlvbkluZm8iOnsiYWR5ZW5MaWJyYXJ5Ijp7Im5hbWUiOiJhZ....",
        "TokenRequestedType": "Transaction"
      },
      "PaymentTransaction": {
        "AmountsReq": {
          "Currency": "EUR",
          "RequestedAmount": 10
        }
      }
    }
  }
}

# Step 4: Make the request
response = adyen.terminal_cloud_api.sync(request)

Optional: perform an abort request

To perform an abort request you can use the following example:

abortRequest = 
{
  "MessageHeader": {
    "MessageClass": "Service",
    "MessageCategory": "Abort",
    "MessageType": "Request",
    "ServiceID": serviceID,
    "SaleID": saleID,
    "POIID": POIID,
    "ProtocolVersion": "3.0"
  },
  "AbortRequest": {
    "AbortReason": "MerchantAbort",
    "MessageReference": {
      "MessageCategory": "Payment",
      "SaleID": saleID,
      # Service ID of the payment you're aborting
      "ServiceID": serviceID,
      "POIID": POIID
    }
  }
}

response = adyen.terminal_cloud_api.sync(abortRequest)

Optional: perform a status request

To perform a status request you can use the following example:

statusRequest =
{
  "MessageHeader": {
    "MessageClass": "Service",
    "MessageCategory": "TransactionStatus",
    "MessageType": "Request",
    "ServiceID": serviceID,
    "SaleID": saleID,
    "POIID": POIID,
    "ProtocolVersion": "3.0"
  },
  "TransactionStatusRequest": {
    "ReceiptReprintFlag": true,
    "DocumentQualifier": [
      "CashierReceipt",
      "CustomerReceipt"
    ],
    "MessageReference": {
      "SaleID": saleID,
      # serviceID of the transaction you want the status update for
      "ServiceID": serviceID,
      "MessageCategory": "Payment"
    }
  }
}

response = adyen.terminal_cloud_api.sync(statusRequest)

OAuth usage (for Partners)

If you are using our OAuth service to make API requests on your customer's behalf, and you already got your Access Token as explained in the OAuth Integration Guide, you can setup your Client like in the following example:

adyen = Adyen::Client.new

adyen.oauth_token = "oauth_token"

The APIs available to use through OAuth in this library depend on the OAuth Scopes defined when Registering your OAuth client.
