Q:

Get campaign preview from Mailchimp API 3.0

I'd like to create preview urls to the campaigns that I've created through API 3.0. How can I get that?
In the response header is the dashboard url. But in the body is no url or "public" id of that.
If there is any alternative to create a preview of the campaigns before sending I am interested in too.

A:

You definitely just answered your own question. The dashboard URL is in the header. There's nothing "private" about that. You can get a preview of the campaign by pulling the content resource off of the object.
