I represent a large company with 8 constant contact accounts. We are using elements of the legacy embedded signup form in a custom way on our website, and we do not want to change to the new inline/generated signup form. For our primary account, we have a "ca" ID and an original list ID ("13") which works. We are now adding additional mailing lists to that account. We've gotten the list IDs of the new ones from the API, and I'm able to modify our form to sign users up to the correct list. The problem I'm having is that when a user signs up for one list, they are SOMETIMES signed up for other lists as well. For example, say we have lists A, B, C, D, and E. We generate a form on our site with the account's "ca" and the "list:input" for each of these. When a user signs up for list A, they only appear on list A. When a user signs up for list B, they appear on both B and C. When a user signs up for D, they appear on D, B and E. There doesn't seem to be a rhyme or reason to it, but my guess is it's a bug in the way the new, longer list ID numbers are being parsed by the legacy embed form. Unfortunately, if we cannot continue to use this form, the company would consider it a dealbreaker. We cannot and do not wish to use the generated inline form, and would seek a different marketing service. We'd like to kindly request that you check whether the list IDs are being incorrectly parsed, or truncated, causing more than one list to be signed up to when a "ca" and a single, correct list ID is specified.
