We're building a Windows desktop application which makes use of the Authorize.net In-Person SDK for Windows as seen at https://github.com/AuthorizeNet/inperson-sdk-windows but I'm not clear on how I can submit a "PO Number" with the transaction. I know it is possible to do via the standard Authorize.net web API as seen at https://developer.authorize.net/api/reference/index.html#payment-transactions-charge-a-credit-card but not sure if I can do so the same via the In-Person SDK for Windows. Having reviewed the code sample I'm only seeing an options to submit a "description" and "invoiceNumber". Does anyone know how I might be able to also submit a "PO Number"?
