I copied the code from code scene and was able to add a new contact. I don't think I changed anything but now when I make the same call I get a response of 400
I can post to List 1, (General Interest), but not to a second list that I created using the Constant Contact web site.
I found the problem to actually be that once I deleted the list using the API, (I actually thought it only deleted the contacts and not the list because I had not logged off and back on from thbe Constant Contact web site). I use their site to add the list back in, but I still can not add new contacts to that site. If I create another list, (list 3), everything is cool again....
OK, I figured out that the list collection number is not related to the Sort Order, so initially when I added List2, then deleted and re-Added, its collection ID is now 3 not 2 which I thought was assigned by the sort order.
