transport.request [transport_request_examples]

It can happen that you need to communicate with {{es}} by using an API that is not supported by the client, to mitigate this issue you can directly call client.transport.request, which is the internal utility that the client uses to communicate with {{es}} when you use an API method.

::::{note} When using the transport.request method you must provide all the parameters needed to perform an HTTP call, such as method, path, querystring, and body. ::::

::::{tip} If you find yourself use this method too often, take in consideration the use of client.extend, which will make your code look cleaner and easier to maintain. ::::
