Frequently Asked Questions

What's the difference between 200 and 204?
200 includes a response body, while 204 explicitly has no body. Use 204 when the operation succeeds but there's nothing to return, such as after deleting a resource.
Can a 204 response have a body?
No. By definition, a 204 response must not include a message body. If you need to return data, use 200 instead.
