I'm currently integrating a Dwolla payment method hack on a Shopify store using a Dwolla button. The explanation of the hack is posted on the Shopify forums here:
http://ecommerce.shopify.com/c/shopify-discussion/t/has-shopify-and-you-abandoned-dwolla-133714
(The hack is being used because Shopify doesn't currently support a viable Dwolla gateway option)
I finally did a live test in both guest checkout mode and checked out with an account signed in to Dwolla.
I don't see any of the transaction details when viewing the payment in my Dwolla account(the detail field is empty) despite having included the following button parameters:
I had incorrectly assumed that data-name, data-desc, and/or data-orderid would populate information in the Dwolla transaction information in my Dwolla account's Payment Activity under Options:Details for the transaction.
My question is this: What happens to the data-name, data-desc, data-orderid information?
Is it retrievable on the Dwolla side?
Is there some way to populate the transaction details with any of the above identifiers?
Clarification: When the customer arrives on the Dwolla secure payment page the identifiers do populate the fields properly. My concern is that as the merchant, when I view the transaction in my business Dwolla account, there is no information that links the transaction to the Shopify order by either the order# or a matching customer name (if the name entered in the Dwolla payment process was different than the name entered in the Shopify checkout process).
The only field that is viewable in the Transaction Details page of Dwolla.com is the data-notes. So, if you'd like to be able to correlate transactions, I would suggest adding the Shopify order ID to the data-notes. The data-orderId field is viewable in the Transactions/ById() API call.
The data-name and data-desc, as you've already discovered, are only used at the time of checkout to list the products purchased.
