Is it possible to POST a confluence page WITH a stock Drawio.image?

[Oscar]

Hi all, 

I've had some recent success automating my companies documentation space. The last hurdle is using REST API POST to create a new page on confluence that includes a Draw.io image. 

I am an engineer in the data warehouse and we use draw.io images to represent fact and dim tables. When a new table is created we manually create the table in draw.io. I fully understand that it is not possible to create a draw.io image that's customised. I'm hoping to find a solution to use a default draw.io image each time a POST is requested - saving time manually adding the image.

Each time I attempt to include a stock draw.io image that are already created on confluence, the post is successful but the draw.io image fails to load. 

Any ideas?!

Thanks, 

Oscar
