I would like to move a to-do to another to-do list. It is possible using API ?
I came across this in my own searches. Send the put request like
PUT https://basecamp.com/ACCOUNTID/api/v1/projects/PROJECTID/todos/TODOIT
with the following JSON in the body
{ "todolist_id":NEWTODOLISTID, }
NEWTODOLISTID is an integer and does not need quotes
