You would like to know how to tie the WePay transaction ID you see in your WePay Dashboard to the Order in your DoJiggy system.
When you log in to your WePay Dashboard and click on any transaction you will see something similar to the following.
In your DoJiggy Dashboard, if you go to Reports->Orders and click on the order number to view, in the Payment History area you will see the Payment Reference. It will look something like this...
