some questions regarding the API.
The API documented on the website covers some functions of Bitfinex.
From the available documentation, it looks like
- the API allows to place orders to the exchange section
- all three segments are supported, according to the API response to https://bitfinex.com/api/v1/symbols
- the API does not yet support any margin trading
- the API does not yet support the lending functions
Are these conclusions correct?
Are there plans to expose the missing functions at some point in the future? Especially will it be possible to control the margin trading via API ?
What are your priorities regarding those missing parts of the API? Will they come in some days some weeks some months?

(I don't intend to push you, rather I just want to judge the situation)
On a related note, at one point the documentation seems a bit confusing:
Say the client wants to make a request to POST
https://bitfinex.com/api/v1/order/newWith a payload of
(...)
To
authenticate a request, take
payload = parameters-dictionary -> JSON encode -> base64
signature = HMAC-SHA384(payload, api-secret) as hexadecimal
send (api-key, payload, signature)
These are encoded as HTTP headers
X-BFX-APIKEY
X-BFX-PAYLOAD
X-BFX-SIGNATURE
So does this mean you send a POST, but you put the actual request payload into a header field?
What are the contents of the body then? does this mean the body can remain empty for authenticated requests, while all non-authenticated requests are sent as GET ?
maybe pointing me to some piece of sample code especially for this aspect would be helpful.
Might be just a fragment of code, any language will do.
