The HTTP method support passing different data types to them…and they will auto-detect the content type…and handle setting the content type header.…So we can pass in the mediaItem as is…and the underlying code will detect it as an object…and set the content type header…to application/Jason.…Let's finish this of by adding a call to .map…so we unwrap the HTTP response.…And for now we can just setup the function it takes…to have a response parameter and an empty body.…
We don't need any data off of this response for this app…but if we did we could handle that inside this function.…Now we can switch over to the…
