Adyen connectors

  • Updated

Adyen is a plug-in that you can configure to process payments when completing an order on your Optimizely Configured Commerce website.


  1. Go to Admin Console > System > Settings.
  2. Search for and select Payment Gateway.
  3. Select Adyen from the Payment Gateway menu.
  4. Populate the following fields with the criteria provided via your Adyen account.
Field Name Description
Merchant Account Number The merchant account number for your Adyen account.
API Key API key value.
Test Mode Default: On. Uses the Ayden test URLs.
Adyen Domain Ayden in a multi-tenant payment gateway and you will have a specific domain, such as [Random]-[CompanyName]
Use Payment Gateway Vault Default: Off. Enables using credit card tokens from the payment gateway that can be submitted to the ERP. Enable this option only if the ERP requires the payment card token to process a transaction, as opposed to the authorization token.


Configured Commerce does NOT store sensitive credit card or profile information.


Configure the Adyen drop-in 

In addition to the regular gateway option described above, there is an Adyen drop-in option available to Configured Commerce customers. This option uses Adyen’s IFrame rather than TokenEx and offers additional features and functionality, such as incorporating a number of payment methods supported by Adyen.  

Card transactions requiring Admin Console entry are unavailable when using the Adyen drop-in. If you want to use the Adyen gateway in the Admin Console, follow the TokenEx implementation detailed above.

Configured Commerce does not currently support storefront saved cards functionality for the Adyen drop-in. If you want to use this functionality with Adyen, follow the TokenEx implementation detailed above.


The Adyen Drop-in is locked behind the system-level IFrame setting. To use this functionality, submit a Support ticket request to update your Sandbox environment with the Payment Gateway IFrame value set to “Adyen.” Once updated, your Sandbox’s IFrame across all sites will be the Adyen drop-in and TokenEx will no longer be usable. 

  1. Configure your Adyen Portal to use the desired payment methods. Some supported payment methods require frontend customization of the configuration object for the Adyen drop-in. 
  2. Generate keys through the Adyen Portal and configure them in the Admin Console. 
    • Generate an API Key and add it to Settings > Order Management > Adyen > API Key. 
    • Generate a Client Key and add it to Settings > Order Management > Payment > Client Key.
    • Generate an HMAC Key and add it to Settings > Order Management > Adyen > HMAC Key. 
  3. Configure the following in the Adyen Portal and Configured Commerce: 
    • Add your Configured Commerce site domain to Adyen by navigating to Developers > API Credentials > Choose Account > Client Settings > Add Allowed Origins. 
    • Retrieve your Merchant Account name by going to Settings > Merchant Accounts in the Adyen Portal and noting the "Account code" field of the merchant account you wish to use. Enter this value into the Admin Console by navigating to Settings > Order Management > Adyen > Merchant Account Number.
    • Set up notifications in the Customer Area for Configured Commerce’s webhook:  
      • URL format: {Configured Commerce Site URL}/api/v1/paymentauthentication/adyenwebhook 
      • Type: JSON 
    • If your URL is live, configure the live URL Prefix in Configured Commerce by navigating to Settings > Order Management > Adyen > Live URL Prefix. You can find the prefix in the live Adyen portal (for example, 1797a841fbb37ca7-AdyenDemo).   
    • Configure the Adyen Domain by navigating to Settings > Order Management > Adyen > Adyen Domain. Since Adyen is a multi-tenant payment gateway, you will have a specific subdomain, like [Random] -[CompanyName] For example, if it were, This value would be "123456 – Optimizely”. 

If the Adyen drop-in is not configured correctly, transaction data may not sync between Configured Commerce and Adyen, as Configured Commerce relies on the Adyen webhook to return transaction details. Be sure to thoroughly test the Adyen drop-in after configuration.


Drop-in Settings 

In addition to the base connector Adyen settings mentioned above, there are a number of settings specifically necessary for the Adyen drop-in itself (see configuration steps above)
