Can I use the API to view my Transactions?

Yes, this section of our API Reference Guide explains how to use a GET request to view a list of Order Transactions in a specific date range as well as Transaction Details for a specific Order.

• The API Call "GET: List order transactions" can be used to view a list of Order Transactions and returns an array of Order IDs created through the API.
• This API Call "GET: show transactions call to /v2/transactions" will return the specific transaction details for a specific order. 

This section explains the same for listing and viewing Refund Transactions.
