I need a bit of help debugging my attempt to setup an integration between FoxyCart and MailChimp via FoxyShop. I followed these instructions
They seem a bit dated, and perhaps not intended to work for v2.0 of FoxyCart. That said, it doesn't seem, at least at first glance, that it does not totally apply. Since 2.0 provides an option on the checkout page for the newsletter opt-in, it seemed to me that it is mainly #3
that is no longer applicable.
Instead of adding the code specified there, I simply added the name 'newsletter_subscribe' (i.e. the name given to the newsletter subscribe input in the 2.0 default checkout) to the code (specified in #2) placed in the foxyshop-datafeed-endpoint.php.
That said, after having run a few tests, the integration does not seem to be working correctly.
