Hey @MasterGardenerFoundation-KingCounty,   Thank you for reaching out to us! So that is a great question in regards to the mobile clicks. I have reached out to our next level support and they have assured me that no matter if the recipient opens the email on a mobile device or a computer the tracking of clicks is always consistent and accurate. With that being said, would you be able to provide a screen shot of the information you found stating that mobile clicks aren't tracked? We would love to look into it a bit further!   ... View more

Hello,   Thank you for reaching out to Constant Contact's API Support.   Our API itself does not include any visual interface to make any selections. I believe you may be referring to the registration page for an event which is given when an event is "Published." One of those URLs would look like this for example: http://events.constantcontact.com/register/event?llr=a9hu7zpab&oeidk=a07ebsbhg3fe67f83e2 .   On a live event if you try to enter something other than a number the value is cleared out and reset to the default value of 0 when you click to any place outside of that box. If a customer/contact is typing in their name or placing an X then when they click the register button, or even just click a blank section of the website then that box changes back to 0. If they click the register button and that value is 0 then they are registered as if they did not purchase that item.     If you are referring to something else please let me know and I'll be happy to assist you and figure this out. ...
