json.dumps() serializes a Python object (such as a dict) into a JSON string, which is required when passing data as the body of an HTTP request. Without this conversion, the requests library would send a raw Python dict representation instead of valid JSON. The other variants either read JSON rather than write it, or write to a file object rather than returning a string.

json.loads() deserializes a JSON string into a Python object - it reads JSON, it does not produce it for use in a request body.

json.dump() writes a Python object as JSON directly to a file-like object, not to a string variable usable as a request payload.

json.load() reads JSON from a file-like object and returns a Python object - it is the file-based counterpart to json.loads(), not a serializer.
