Pass arbitrary JSON objects in request body

How can I pass JSON objects with arbitrary structure in the body of a request? For responses, it is possible to just specify application/json: {} but that seems not to work for request bodies. Thanks!

Not sure if the OP really meant “arbitrary JSON objects”, as in the title of the issue. If it was meant “JSON objects”, I guess the right schema for the request body would be:

application/json:
  schema:
    type: object

Otherwise, the schema mentioned above (schema: {}) would be satisfied by, e.g., an array, a boolean, a string… well, anything, as long as it is valid JSON.

This raises an interesting point – how does one specify “the body can be anything at all, including being empty”? An empty body is not valid json. Or, as a corollary: how does one specify “there should not be a body; if there is anything, this is a violation”? Perhaps there is a FAQ or cookbook that I have not found yet 😃
