There are ‘markup’ and ‘html’ keys, which are describing the card’s body. While this is very convenient when fetching body text - currently it is giving us problems when creating/updating cards: you can not use only one of them when defining body text. And ‘html’ key overrides ‘markup’ if you use different text in ‘markup’ and ‘html’ keys.
So, the question is: why it is impossible to use only one of the keys (‘markup’ OR ‘html’) when creating or updating card. Do we really need to duplicate the same text first using markup syntax and then using html-syntax? This does not looks very productive and may lead to formatting errors.
