Solidus-Adyen

NOTICE From July 2016 Adyen will no longer support SHA1 HPP's, this extension is not only compatible with the SHA256 skins.

Adds support for Adyen Hosted Payment Page payments to Solidus stores using the Adyen gem.

Due to the way Adyen's payment API works, the payments created using the AdyenHPP method's behavior differ significantly from normal payments.

Adyen's API is totally asynchronous, Solidus makes a request to modify a payment, and some time in the future Adyen responds to a specified endpoint with the result of the action. After capture/refund/cancellation the payment will move to a processing state, and will be change to the new state after the notification is received from Adyen.

Installation

Add this line to your application's Gemfile:

'solidus-adyen', '~> 1.0.0'

Then run:

ndle install
ndle exec rake spree_adyen:install:migrations
ndle exec rake db:migrate

Usage

To integrate with Adyen payments you'll need to request API credentials by signing up at Adyen's website.

This gem only supports Adyen HPP payment methods. At this time there are no plans to support the direct payment methods.

A payment method called AdyenHPP added to the list of available payment methods allowing stores to authorize payments using Adyen Hosted Payments Page solution. This works much like paypal and similar services where the customer is redirected to Adyen at the payment step, and is redirected back to your store after they have completed payment.

Please look into the Adyen gem wiki https://github.com/wvanbergen/adyen/wiki and Adyen Integration Manual for further info https://www.adyen.com/developers/api/

Configuration

Application Server

Define two environment variables $ADYEN_NOTIFY_USER and $ADYEN_NOTIFY_PASSWD that are available to the rails server. These will be used Adyen to authenticate with the application server when it POST's notifications which will update the state of a payment.

Obviously these should be kept secret as they will be used to update the state of payments.

Server Communication

To receive notifications from Adyen about the outcome of payment modifications (authorization, capture, refund, cancellation) you will need to configure your merchant account with Adyen with the proper url to the Spree::AdyenNotifications#notify action.

ke routes | grep spree/adyen_notifications#notify
yen_notify POST /adyen/notify(.:format) spree/adyen_notifications#notify

is the default path for the endpoint.

It is worth noting that Adyen will only issue notifications to servers that are running on standard HTTP ports, so your rails server must be accessible on port 80, 8080, or some other http-alternative port.

Visit Settings > Server Communication and click 'edit & test' for 'Standard Notification', the other notifications are not used by this integration and may cause undefined behavior if enabled.

Use the following configuration:

Field | Value —————————-|————————————————— URL | http://your.server/adyen/notify or whatever you have changed the previous path to SSL Version | SSL Active | checked Service Version | 1 Method | HTTP POST Populate SOAP Action header | unchecked User name | $ADYEN_NOTIFY_USER Password | $ADYEN_NOTIFY_PASSWD

Save your changes and click 'Test Configuration', everything should be successful.

If you get errors saying that it was unauthorized you forgot to set the username and password environment variables on the server.

Skin

A skin defines the look, feel, and behavior of the hosted payment page.

To set one up visit Skins and edit an existing skin or create a new one.

Fill in

field | Test platform | Live platform ————|—————————————–|————————- HMAC Keys | some secure key | some secure key Result URLs | http://your.site/checkout/payment/adyen | http://your.site/checkout/payment/adyen

Write down the values you use for HMAC keys as you'll be using them later when your create the payment method.

AdyenHPP Payment Method

In the Solidus admin, go to your payment methods and create a new payment method using the Spree::Gateway::AdyenHPP provider.

It is very important to note if any of the following values entered have any trailing or leading whitespace everything will break.

Use the following config

Field | Value ————-|—————————————————————— Server | test Auto Capture | false Environment | Development Display | Front End Active | Yes

Fill in Api username, Api password, Merchant Account, Shared Secret, and Skin Code with the values found using the steps below.

To find your Api Username and Api password:

• Log into your Adyen account
• Click Settings > Users from the left hand navigation
• In the table, change the filter by selecting System from the select on the left hand side of table header (Customer is highlighted by default)
• Click the linked value in the Name column you wish to use.
• Under the User Account Details fieldset the value of User Name is your Api Username and the value of Password will be your Api Password

To find your Merchant Account:

• Log into your Adyen account
• In the top navigation bar beside the magnifying class click on the box that's text is the same as your username
• In the table, under the column called Account Code is your merchant account name

To find your Skin Code and Shared Secret:

• Log into your Adyen account
• click Skins from the left hand nav
• Click the link under the skin code column whose value for the column valid accounts matches your Merchant Account
• Within the Skin details field-set
• The value for Skin Code is the value of text input with the same name
• The value for Shared Secret is the value of text input labeled HMAC Keys

To verify that your payment method is configured properly:

• Go to your Solidus store's homepage
• Add an item to cart
• Click Check out
• Enter an Address
• On the Payment step, select your Adyen payment method, and then 'pay with Adyen' if no payment methods show up here check your server logs, you likely don't have the payment method configured properly.
• You should be redirected to Adyen's portal
• Congratulations!

HPP Directory Lookup

This gem supports adyen directory look ups. The default checkout view does provide the functionality to asynchronously load the payment methods, but if you want to include this feature in your own custom checkout views you can follow the instructions below.

Include spree/checkout/payment/adyen.js on your checkout page. Add an element that has an id of adyen-hpp-details and has

: {
l: directory_adyen_hpp_path(
order_id: @order.id,
payment_method_id: payment_method.id)}

You can also skip using the provided js if you really want to! Important thing here is just to make a get to directory_adyen_hpp_path with the order_id and payment_method_id and then insert the resultant html somewhere in the DOM. This will then make the request to adyen to get a list of payment methods that are supported and then render the payment links.

If you just want to style the list of Adyen payment methods, just override the spree/adyen/hpps/directory view. Take a look at the existing version to get an idea of what is available in the view.

Testing

=postgres bundle exec rake test_app
pec
 spec/dummy
ke solidus-adyen:factory_girl:lint

Development

My prefered method of setting up a sandbox is with

bin/bootstrap.sh
spec/dummy/bin/rails s

You will need to reverse tunnel or make your server publicly available by some other means - and update the server communication as well as the skin's url with the proper end point to receive notifications.

Terminology and other API information

More info about Adyen can be found here. Includes information about the adyen soap api and the parameters that it accepts.

e.g.

paRequest, md, issuerUrl, resultCode, PaReq, MD, TermUrL, etc.

If you find some variable that is not documented in the gem, it's likely defined here.
