Is this possible via the API? We have a campaign we send out weekly to the same list of users, and I'd like to be able to automate it.
Sorry, but there isn't an API method that has the same function as the Edit and Resend function that's in the web application.
However, if your campaign content is the same, and you can host it somewhere, then you should be able to use the 'Creating a draft campaign method' (http://www.campaignmonitor.com/api/campaigns/#creating_a_draft_campaign) to create your campaign every week, then use the 'Sending a draft campaign method' to send it (http://www.campaignmonitor.com/api/campaigns/#sending_a_draft_campaign).
I hope that helps! Feel free to get back to us if you have any other problems or questions.
This just answered my question -> https://www.campaignmonitor.com/forums/topic/8093/how-to-send-a-campaign-to-a-specific-segment/
this is very unfortunate and seems so incomplete.
