We are in trouble to add a new contacts to my campaigns which we added dynamically by our php scripts, we have done earlier in older versions by using createcontact() function but in v3 we are not able to add the lists or a contact so we are not abled to schedule by php
Thank you for reaching out to Constant Contact API Developer Support.
At this time you can create an email campaign, but not yet schedule one with our V3 API. We're still in the process of building out additional features for V3. Our V2 API has the scheduling and reporting endpoints implemented and available for use; you are welcome to still develop with our V2 API. For documentation on this in V2 see the following links.
