What I'm trying to achieve is auto submit a subscribe form (with specific user details) to my email provider (similar to mailchimp), when a new user register to my joomla site.
I already defined a plugin with an event that triggers when a new user register to my site.
But I'm really not sure how to auto submit a form or a url with the user details.
For example, the following line would do what I need but I don't know how to trigger it from my plugin:
Any ideas how can I accomplish this would be really appreciated.
