Wufoo and Campaign Monitor Integration API

Here is what I am looking to accomplish: 1. I use Wufoo forms to capture all sorts of data. Most of the fields have fees attached that is added behind the scenes in Wufoo. I do not like Wufoo email capabilities. 2. Using Campaign Monitor, all information entered in the Wufoo form could be transfered to Campaign Monitor where is can prepopulate using personalization tags in an HTML autoresponder. 3. The email would function as an invoice and send automatically. I have spoken to many support staff at both Wufoo and Campaign monitor and know that this problem can be solved using webhooks and API. There is an existing integration between the two companies that allows most of this information to flow easily. The problem comes with the Purchase Total portion.
