Fetches a list of transactions for a virtual card for a specified period. The transactions are returned in groups called pages. You must specify how many records will be included in each page (up to 100) and then specify which page you want Nium to return. To determine the number of pages, you will need to use 'get virtual card transactions count' first to get an overall count of the total transactions for the period.
