API changelog

Enhancement/Fix	API Reference	Description
Fix	Payments	Previously, the API Reference for the Save Card Token and Run Card Transaction endpoints indicated that you should send the card security code as an integer. But, because the security code may start with a leading zero (0). If you send the code as an integer, you will likely run into errors. However, since the API has always supported this parameter as either a string or an integer, we have not had to make a programming change. Instead, the documentation has been updated to indicate that you should send the `securityCode` parameter as a string. (1/11/2023)
