Once you have processed an Authenticate transaction through your account you are then able to authorise this to receive the funds.
Before doing so however, you must first ensure that the user you plan on performing the authorise with has the privileges to do so.
When you are attempting to authorise a transaction it is important to know;
After logging into the account you will first need to locate the transaction you wish to authorise.
To do this select the transactions tab within MySagePay and use the options available to locate the authenticate transaction.
Now that you have located the authenticate transaction you are ready to authorise.
Simply click on the transaction you wish to authorise, you will then be presented with the transaction detail screen.
The authorise button will be displayed on the bottom right corner of the transaction detail screen. Select this button to be taken to the authorise screen.
Enter the amount you wish to authorise, and select which fraud prevention rules you would like to be carried out on the transaction.
When you are happy with this, select authorise and this will complete the authorisation of your transaction.
