Quire how to add a task to a board and a board column with your API, i can manage to create tasks but can't assign them to a board with your API.
to add a task to an existing board set the board
property of the PUT /task/{oid}
action
to add a column use the addColumn
property of the PUT /board/{oid}
action
UPDATE:
to place a task into a specific board column you have to set the task status corresponding to the column value
(e.g {"status": 10}
) PUT /task/{oid}
The task will then 'jump' into the matching column of your board
