I am searching for a solution or tutorial regarding how to activate a http call or function/method/class every time a recurring/purchase/checkout is created
while using Magento.
I want to book all the sales within an external accounting service.
I checked out this link: http://www.magentocommerce.com/wiki/doc/webservices-api/api, however it does not seem like it may activate on events in Magento?! Here you
have to result in the calls external.
Hopefully someone out there can help me out of it and get me what I exactly want
