Edit campaign section using MailChimp API

Here's what I'm trying to do:

• I am creating a campaign using a template using Mailchimp editor
• I add an image and text section on the side of the image at the top of the campaign.
• Image and text should be dynamic and filled via API

I was able to get campaign content via Python and Django APIs.

But the tricky part is how can I dynamically add content to the campaign? I am not quite clear on how the campaign / update works, and how to consistently get the added title area for editing (which should always be checked out no matter what template is used)

Any pointers?

Thank!
