Adyen - Configuration

Modified on: Fri, 24 Nov, 2023 at 8:16 AM


The steps below will help you set up the Adyen Payment processing features. Please note that you need first to have the Payment autopilot add-on enabled for your Clock PMS+ subscription and a LIVE Adyen Account. Being a payment processing institution, Adyen has security procedures for your account to pass before becoming live.

Important: This article should be considered mostly as information. Settings for the Adyen interface are very extensive and thus we strongly recommend to perform the configuration together with our Customer Service team. Any missed setting or wrong input in the configuration may lead to the interface not working as intended.

Company vs. Merchant accounts in Adyen

When working with Adyen, you will come across two elements that you need to differentiate:

- your Adyen 'Company' account

- your Adyen 'Merchant' account/s

Company account: that is the 'umbrella' and can contain several merchant accounts.

Merchant account: in the majority of cases, you will have at least 2 merchant accounts in Adyen: one that will process Online transactions - Ecommerce and MIT - and another one that will process POS transactions (transactions made on the physical card terminal supplied by Adyen). 

Note: If you are a multi-property business, you will have more merchant accounts - e.g. if you operate 2 hotels, you will have 4 merchant accounts (1 Ecommerce and 1 POS merchant account per property). 

It is important to differentiate those and know how to select a Company level or Merchant level as some of the configurations below are specific for the type of account.

Navigating between Company/Merchant accounts is done through the button on the top left corner of your Adyen account. Simply click on either the Company account or one of the Merchant accounts.

Token Groups

For the proper operation of the interface, please request from the Adyen support team to create a 'Token Group' with the following details:

  • Company Account Name -> your Adyen company account name
  • Name of the token group -> ClockPMS+
  • List of merchant accounts to be included -> list all your merchant accounts within your Adyen Company account
  • Environment - live or test -> always LIVE
  • Should this group be set as the default? This means newly created merchant accounts will also be added to the token group. ->  Yes, set as default

and to have the following setting enabled:

  • allowModificationsOnSameCompanyAccount


To start with the configurations, log in to your Clock PMS+ account. Select Settings -> All Settings -> Payment Processing-> Adyen v2 and click on the '+' button on the top right and enter the information.

  • Adyen Merchant account code (1) - enter your Adyen ecommerce merchant account name.
  • API Key (2) - create API credentials in Adyen and enter the API key. Find out how to create API credentials HERE.
  • Currency (3) -  Select the currency you operate with and in which amounts will be sent to Adyen.
  • Quick capture auth age (4) - capturing of blocked amounts of some pre-authorizations took very long and thus blocked your work. With this setting, you can indicate a period within which we can apply different behavior.


- Any amounts pre-authorized up to 7 days in the past will be processed without waiting for a response (which may take an indefinite amount of time - minutes, hours, etc.).

  - For pre-authorized amounts older than 7 days, the current behavior, namely waiting for confirmation, is maintained.

In case you do not want to use the speculative mode of operation for both Capture pre-authorizations and direct payments, enter 0 for the value of the Quick capture auth age field. You will then need to wait for a response from the partner to complete all Capture operations.

  • Live URL Prefix (5) - obtain the Prefix by logging in to your Adyen account and from the navigation bar on the left select Developers -> API URLs. Copy the Prefix and add it to this field.

  • Live API endpoint location (6) - select based on your location.
  • Live (7) - select once all configurations for the interface are completed.
  • Save. 

Once you save, you will see the following screen. Associate your PMS/POS account with the merchant account and click on the your Adyen merchant account code to continue config.


Important: Once you have completed the above configurations, two new fields will pop-up - Notification endpoint username; Notification endpoint password.

  • Notification endpoint username; Notification endpoint password; Notification endpoint URL

1. Log in to your Adyen account. Make sure you are on a 'Merchant account' level.

2. Select 'Developers' from the left navigation sidebar. Click 'Webhooks' and on the next page, click '+Webhook' and add 'Standard Notification'.

3. On the next page select 'Server configuration'.

4. Copy the Notification endpoint URL (3) from Clock PMS+ and paste it into the ‘URL' field

5. Change Method to JSON.

6. Change ‘Encryption protocol' to 'TLS v1.2'

8. Click 'Apply'

9. Click on ' Basic authentication' section, enter the Notification endpoint username and password (1,2) and click Apply.

10. Click on 'Save changes'.

Drop-in configuration (Alternative payment methods)

The Drop-in module allows you to offer other payment methods and not only Card payment. These span from well-known globally payment options such as Apple Pay, Google Pay and PayPal to more local ones such as iDeal, Vipps or Bancontact. Please check THIS article for more details.
