1. Introduction

In this guide, we explain you how to use your ePDQ account, which we sometimes refer to as the Back Office.

2. Login screen

To access your ePDQ Account menu, you have to log on to the Back Office.

Depending on the environment that you want to access you have to use one of the following URLs:

  • Test: https://mdepayments.epdq.co.uk/ncol/test/
  • Production: https://payments.epdq.co.uk/ncol/prod/

To clarify which environment you are logged on to, the tab containing the login section will be marked with either the label "Identification TEST" or "Identification Production".

Before you log on, you still can change the environment by clicking either the "Access to test" or "Access to production" link below the login form.

In each environment you have the possibility to log on with:

  • 'PSPID' and 'Password'. This Login section is displayed by default.

  • 'UserID', 'PSPID (Optional)' and 'Password'. You can display this Login section by clicking the "Login as user" link. Use this possibility if your account has more than one user registered and you want to log on as one of these users.

Once you are logged on, the Account menu is displayed on top of the page.

The menu contains the following sections:

  • 'Home'
  • 'Support'
  • 'Configuration'
  • 'Advanced (optional)'
  • 'Operations'

On the upper-right hand corner of your account homepage, you can see the "User profile" drop-down icon and the "Language selection" icon.
1. User profile drop-down
The user profile drop-down displays the user profile, user role, date and timestamp of the last login, and the time zone. Through this option, users can do the following:
- Reset their password by clicking the "Change password".
- Log out of the session by clicking "Logout".

2. Language selection drop-down
Users can select the language which they want to display the Back Office content. There are currently six languages to choose from: English (EN), French (FR), Dutch (NL), German (DE), Spanish (ES), and Italian (IT).

3. Account Menu

3.1 Home

Once you're logged in, you are on the home page of your account. On the home page, you can find general and technical messages and announcements about our platform, as well as alerts specific for your account (e.g. transactions).

If it's your first login session (usually in the test environment), you will see a list of steps to follow.

To find out more on how to set up your account, go to Test Account creation.

3.2 Support

3.2.1 Support menu

In our Support section you can find:

  • Integration & user manuals
  • Frequently Asked Questions (FAQ)
  • Platform releases (with information on our latest platform changes)
  • Our contact details

3.3 Configuration

3.3.1 Password

Here you can update passwords for your user(s). You can change your password at any time; in two cases, however, our system will automatically ask you to change your password for security reasons:

  • You have logged in for the first time with a password that has been newly issued by our system (the initial account password, a new password you were issued via the "Lost your password?" procedure or a "New password" action in the user manager page) as the password automatically expires upon the first login.
  • You have been using a password (which you chose yourself) for a period of 90 days.

To change your password, click the "Change password" under the User Info icon on the upper-right hand corner of your Back Office account and follow the instructions. You will be asked for your current password, and to enter and confirm your new password. For added security, you can also activate or deactivate two-factor authentication. See below for more information.

Note: If you wish to change the invariable API password, select the API USERID in the USERID drop-down box on the "Change password" and set the new password.

Two-factor authentication

Two-factor authentication (2FA) adds an additional layer of security to your account by requiring a second dynamic passcode on top of your standard ePDQ username and password. Once the 2FA verification is activated, you will be required to enter a time-based one-time passcode (along with your existing login password) as unique verification code to log into the ePDQ account. Please note that a mobile device is required to generate the time-based one-time passwords.

Please install an authenticator application on your mobile device. The ePDQ account supports the following authenticator applications: Google Authenticator (Android, iOS, BlackBerry), Authenticator (Windows Phone). Please note that from the moment 2FA authentication is activated on your account, it is also linked to your mobile device. Before changing or resetting your mobile device, we strongly advise you to deactivate your 2FA authentication before setting it up on your new device.

How to activate

  1. To activate 2FA in your ePDQ account, go to Configuration > Password > One Time Password configuration.
  2. You will be directed to the One Time Password configuration page. Open the authenticator application on your mobile device and scan the QR code displayed on the page (or fill in the number right below the QR code).
  3. Confirm the activation by entering the 2FA passcode.
  4. Enter your ePDQ account password to confirm the modification and click “Submit”. You have now activated 2FA in your ePDQ account.
How to deactivate

You can deactivate 2FA for your user:

  1. Go to Configuration > Password > One Time Password configuration.
  2. Open the authenticator application on your mobile device. On the One Time Password configuration page, enter the 2FA passcode displayed on your mobile device.
  3. Confirm your request to deactivate 2FA by entering the ePDQ account password to confirm the modification and click “Submit”.
As a merchant admin (with access to user management), deactivate 2FA for another user.

  1. You can also request an administrator (with access to user management) on your enabled account to deactivate 2FA.
  2. Go to User Management > select the user details > uncheck One-time password active.
How to login with two-factor authentication
  1. Enter your user password at the ePDQ account login page.
  2. Once redirected to the 2FA page, enter the 2FA passcode.
  3. Proceed as you would normally do.
  • All 2FA passcode can be found by opening the authenticator application on your mobile device.
  • The authenticator generates a new passcode every 30 seconds.
  • Always enter the passcode associated with the scanned QR code. Other passcode from past QR codes will not work.
  • A QR code does not display when 2FA is already activated. Once 2FA is deactivated, a new QR code displays for 2FA to be activated again.

By selecting this option, the time is also automatically adjusted to daylight saving changes.


You can easily change your phone number in our Back Office. After logging in, please go to Configuration > Account > Your administrative details.

If your VAT number has changed, you need a new PSPID / account. Please contact your account manager to create a new account.


The Back Office is the secure website where you manage your ePDQ account. Once you have logged in, you can check and edit your administrative details, manage your payments, change your technical settings and much more. To log in, you simply need your payment service provider ID (PSPID) and your password.

A User ID identifies the specific user of an account.

If your account has more than one user, you log in by filling in your USERID, your payment service provider ID (PSPID), if needed, and your password. Please make sure you click on the 'Log in as user' link so that all three fields are displayed.

If your account only has one user, you will not need a USERID. You will log in using only your PSPID and password, so please make sure your login screen only displays two fields. If you can see three fields, click on the 'Log in as PSPID' link on the bottom left of the screen to log in as a merchant.

PSPID stands for payment service provider ID. It is the name you chose when you first registered  to identify the business your account is linked to. You need your PSPID and password to log in to your account. 

In your ePDQ account menu, you can easily lookup your transactions by choosing "Operations" and then clicking either "View transactions" or "Financial history", depending on the type of transaction results you're looking for.

Go to Consult your transactions for more information.

By default you can send goods or deliver your service once a transaction has reached the status "9 - Payment requested". However, although status 5 is a successful status, it's only a temporary reservation of an amount of money on the customer's card. A transaction in status 5 still needs to be confirmed (manually or automatically) to proceed to the status 9, which is the final successful status for most payment methods.

Go to Transaction statuses for more information.

You can easily refund a payment with the "Refund" button in the order overview of a transaction (via View transactions). If your account supports it, you can also make refunds with a DirectLink request or with a Batch file upload (for multiple transactions).

Please note that the Refunds option has to be enabled in your account.

Go to Maintain your transactions for more information.

A full green thumbs-up icon means that the transaction was completed with a 3-D Secure authentication method, such as Digipass or a card reader. However, it doesn't necessarily mean the payment itself was processed successfully. Therefore, you should always check the transaction status to know whether you'll receive your money.

Go to Transaction statuses for more information.

If you want to check specific details of an order/transaction or perform maintenance on transactions, you should use View transactions. "Financial history" is the most convenient to periodically check incoming and outgoing funds.

For more information, go to View transactions vs Financial history.

There are different reasons why you can't refund a transaction. You need to consider the following (with the condition that the Refund option is enabled in your account):

  • The transaction is in an "incomplete" status, such as a pending or erroneous status (9192 etc.) that doesn't allow the refund operation.
  • If the transaction is authorised (status 5), at which point no payment has been made yet. In this case you have to cancel the authorisation instead of refund.
  • The used payment method doesn't support the refund functionality, which can be the case with certain debit cards, web banking methods and "offline" payment methods such as Bank transfer.
