Markdown support in tables through API

How can I enter Markdown data in Coda tables through the API? I have gone through all the documentation but I am not able to find this.

I can get the data (formatted) in markdown format through the API but can’t write it.

The lack of this has been a huge problem for me. It seemed so basic I didn’t bother validating it before starting quite a large integration project, and this stopped me dead in my tracks a week in.
