Accessing website API from fmp8

[Cassetti]

Hey all, quick question.

I am very new to API's and am looking into the possibility of connecting our filemaker pro prospector database list with our www.icontact.com email marketing provider.

Here is the page with a brief overview of the API

Could it be done using filemaker pro 8? or could we only do it using filemaker pro 8.5 with the web-viewer function?
