In the parameter array of the REST API call 'subscriberAdd', does "confirmed=1" mean the confirmation request email will not be sent? That would be exactly what I want, control over whether the confirmation request is sent or not, depending on whether the user is subscribing as part of registering an account on my site (in which case they will already get a confirmation email, so I don't want to send 2 of them).
Or should I use 'listSubscriberAdd' without sending a confirmation email?
I'm evaluating using PHPList with my existing website because ActiveCampaign, which I currently use, no longer works with my newly-upgraded PHP 5.6, and is no longer supported unless I go to their hosted version, which I can't afford. I'm hoping to do a fairly simple replace of ActiveCampaign's API calls with PHPList's API calls i my site code - but I'm sure it won't be simple!
