We really like the dashboard text card which allows us to easily add some more information / links to our metabase dashboard. One question we have is the following:
Is is possible to programatically update the text through (e.g. an API endpoint)?
The last resort would be to modify some entry in metabase DB but we would like to avoid messing with the SQL data directly
The test code related to the front end around here in combination with the PUT method for a card hints at that you need to give a display set to "text" and a visualization_settings with a text containing the markdown. Guess a GET on a text card will give you the specifics?
