How to access Select “Transactions” from the left and then “Transaction search“. Perform a search and click a transaction reference displayed in the results table.
OR; type in the full transaction reference into the universal search, at the top of any MyST page. Actions can be found in the form of buttons, displayed beneath the transaction details.
When the browser window is too narrow to display all options available to you, they are collapsed and hidden under a single “Actions” button. Click this button to view possible actions.


The actions that can be performed are dependent on the state of the transaction selected. For example, you cannot refund a transaction that has not settled.




A Re-Auth is where you can process a new Authorisation against the customer’s card. Before processing the request, you are able to change the expiry date and also set a different amount to the original transaction.

As the security code is not stored on our servers, you may need to input the details again, or the card will not pass the security code check.

If re-using previously stored credentials, Visa and Mastercard have mandated that you set the Credentials on file field to “2 – Scheduled payment using stored credentials”.
If this transaction is to be a Merchant Initiated Transaction (MIT) (opposed to a Customer Initiated Transaction or CIT), Visa has mandated that you specify the reason for the payment, by selecting a value in the Initiation reason field.


You must ensure the initiation reason selected correctly represents the reason for the new payment. Visa may introduce new values to this list in the future. Please refer to Visa’s own documentation for further information.

Rules cannot be inherited by child authorisations. They will only be performed on Re-Auth transactions if active in the Rule manager.




You can process a full or partial refund for a settled transaction (with request type “AUTH”). The following criteria must be met in order for refunds to be processed:

  • The transaction being refunded must be settled (in settle status “100”).
  • You cannot refund a greater amount than was originally settled.
  • The payment details must still be valid (e.g. the card cannot be beyond its expiry date).
If you wish to update the expiry date for a refund, you will need to click the + icon to display the field, which is hidden by default.




You can perform updates on a pending transaction (settle status “0” or “1”) using the “Update” option. Updates that can be performed include:

  • The transaction can be deferred, either by changing the settle status to “2” (Suspended) or by changing the date the transaction is scheduled for settlement.
Any transactions that have not settled after a certain period following the authorisation are regarded as cancelled by our system, as the authorisation code is no longer valid. This is usually after 7 days, but can vary depending on your account.
  • You can update the amount for a transaction, providing the new value is less than the amount originally authorised.
  • The order reference can be updated.
  • The transaction can be cancelled by changing the settle status to “3”.
If you update a transaction to settle status “3”, the transaction is permanently cancelled, and cannot be updated at a later date. The funds reserved on the customer’s account will be released at a future time as determined by the issuing bank.


If you have selected multiple transactions for update, and need to change all of their settle statuses to the same value, you can use the “Options” area that is shown towards the top of the page:



Account check

An account check allows a card/account to be validated by checking the customer’s account, address and security code values are valid and that it is acceptable to proceed with the transaction. This feature is only available with select acquirers and the number of checks performed may differ based on the payment type. To find out if your acquirer supports account checks and to activate it on your account, please contact our Support teamNo funds are reserved or transferred by the account check process, but you may specify an amount. This amount is inherited in future transactions that refer to the account check as a parent transaction.



Risk Decision (requires Protect Plus)

A Risk Decision request analyses the customer’s billing, delivery and payment details using a rule-based system to detect suspicious patterns in user activity. The system will assist you in making a decision on whether to process a customer’s transaction based on the perceived level of risk. Checks performed include:

  • The industry’s largest negative database.
  • Neural-based fraud assessments.
  • Tumbling or Swapping, where there is an unusual usage pattern in the card number, expiration date or customer details associated with a transaction.


The Risk Decision system will analyse these details and return the following results:

  • ACCEPT – The details are not deemed suspicious.
  • DENY – The details are suspicious and a transaction should not be performed.
  • CHALLENGE – Further investigation is recommended.
  • NOSCORE – Transaction was declined by the acquirer before checks were performed.
