I can't access the Adyen POS Application. It says "Credentials invalid".

The most common reasons that you see this message are:

  • Your login credentials are incorrect:
    • Make sure that you are using a webservice user. This is different from a user used for the online customer area; the webservice username typically begins with ws.
    • Check that your Merchant account, Username and Password have been entered correctly. These login credentials are case sensitive.
    • If you are trying to log in to a test account, make sure the username ends with :0xfacefeed
    • If you are trying to log in to a live account, make sure your username does not end with :0xfacefeed
  • The user is missing the Submit POS payments user role. To activate this role, contact your admin user. If you are the admin user, you can add this role to the user via the customer area > Account > Users; if you don't see the user role, please contact Support.
