Is it possible to change the status of an email campaign from 'SENT' to 'DRAFT' using the REST API.
Changing a campaign from 'SENT' to 'DRAFT' is not possible using the API or by logging in to our website. If you are logged in to the website you can do a Resend or a Quicksend of a 'SENT' email. The only way to get a 'DRAFT' version of that email is to make a copy of that email.
You cannot make a "copy" of the email using the API; however you can take the exact same content and give it a new name which would basically be the same thing. To do that you would use the POST method which can be found here. (http://developer.constantcontact.com/docs/email-campaigns/email-campaigns-collection.html?method=POS...)
