<br></blockquote></div><br><div>I made an api for the web requests- the call isn't so straightforward, all the information is sent in POST formatted a certain way and there's also a credentials part with a token and other bits with secrets used to auth the request. So for instance I call the list dir method in the api and get back a Response type object based on the web response. Is there still way I can defer the returning of that web call, or would I need to tear the api apart to use twisted deferred objects internally? or is this something Agent could deal with?</div>
