How to unsubscribe user from only one list?

[SteveK431]

Is it possible to unsubscribe a user's email address from just one list.

For example:

We have 10 lists and the user's email address is subscribed to 3 of them. We have the user's email and now through the API we want to unsubscribe them from off one of the email list but keep them subscribed to the other two.

Hello,

You can accomplish this with two API calls.  First, you make a GET to the Contacts Collection API, doc located here:

http://developer.constantcontact.com/docs/contacts-api/contacts-collection.html?method=GET

You provide the email address as an additional parameter, and get the contacts information back.  You also now have the Contact's unique id, so you can perform a PUT to the Individual Contact after changing the lists.  The doc on that is located here:

http://developer.constantcontact.com/docs/contacts-api/contacts-resource.html?method=PUT

That will allow you to update the lists a contact is subscribed to.  Hope the information helps.
