将附件添加到 Trello 卡

Question

In my program I have a big canvas where I extract multiple selected regions and draw the regions to separate new small canvas.

I want to post the newly created canvas to trello as attachment using this API POST /1/cards/[card id or shortlink]/attachments.

The files are not saved in a database or in local storage.

I'm able to attach a Link to a card but the attaching a file is not clear and only documented with a curl command.

Is it possible to attach a Canvas and how using javascript?
