BitFinex API call returns 400 bad request - "Could not find a key matching the given X-BFX-APIKEY" I dont know what I'm doing wrong, but everytime I try send post request "https://api.bitfinex.com/v1/balances" or some else I got this answer "Could not find a key matching the given X-BFX-APIKEY".

I was trying some aplication, make-online-request-sites, my own program and code from this page BitFinex API call returns 400 bad request. 

My api-key looks like dddd where d is digit.

Maybe I dont know how looks like key-api. This should be first column on this site https://www.bitfinex.com/account/api, right? Second is api-secret. Really... I cant understand what I'm doing wrong...
You see the API key once, when it's generated. 



You have to generate another one.

It's sorta mystifying that they would show the API secret whenever you look at that page, but only show the API key once. I dunno why they did that.
