I am trying to use authorize.net's php-sdk to charge a customer profile which is working but I can't find the write way to send the poNumber along with the data. In the following link, I am using the part where it says Creating Transactions, but no where do I see how to add poNumber.
https://github.com/dragonjet/AuthorizeNet-PHP-SDK/blob/master/doc/CIM.markdown#creating-transactions
There are so many different ways to send a transaction through to authorize.net, but the method I am using is shown in the link above. I need to get it to work like that but with poNumber. Anyone know how to do this?
Thanks
