How to set a checkbox using POST request with Services Module? I am trying to set a checkbox in a display using a post request by setting the value of the mark field to 1, specifically field_mark_as_discounted. But I can't seem to be able to achieve that. Note: The checkbox functions well when set manually. If anyone has come across this issue of setting a checkbox using post request please share.
This probably is the JSON you need for that field when POSTing:

field_foo: { und: [ { value: 1 } ] }


Remember, the Services module is dependent on which widget you have selected on the Manage Fields page for your entity/bundle.
