client_id in Bitstamp's API

In Bitstamp's API documentation, a client_id is mentioned. It is used to generate a signature.

But I couldn't find how I can get that client_id.

Any hint on that? Many thanks.

Did you register for an API key via their instructions? They say:

To get an API key, go to "Account", "Security" and then "API Access". Set permissions and click "Generate key".`

Once you have the API key, you use a HMAC encoded of the API key, API secret, and your customer/client id. You should be able to get your client id by going to the "Account Balance" page, where I believe it's referred to as your "Customer ID".

Use this code to get idea. This is Ruby code

require 'open-uri' require 'json' require 'base64' require 'openssl' require 'hmac-sha2' require 'net/http' require 'net/https' require 'uri' def bitstamp_private_request(method, attrs = {}) secret = "xxx" key = "xxx" client_id = "xxx" nonce = nonce_generator message = nonce + client_id + key signature = HMAC::SHA256.hexdigest(secret, message).upcase url = URI.parse("") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true data = { nonce: nonce, key: key, signature: signature } data.merge!(attrs) data = data.map { |k,v| "#{k}=#{v}"}.join('&') headers = { 'Content-Type' => 'application/x-www-form-urlencoded' } resp = http.post(url.path, data, headers) console_log "" resp.body end def nonce_generator (Time.now.to_f*1000).to_i.to_s end 

The page where you change password on Bitstamp presents you your client id (contains letters and digits).

I have some probelm with bitstamp api
below is my code php

$message = $nonce.$client_id.$api_key; $signature = strtoupper(hash_hmac('sha256', $message, $secret_key)); $post_string = 'api_key='.$api_key.'&signature='.$signature.'&nonce='.$nonce; $url = ""; $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT, 4); curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string); $json = curl_exec($ch); if(!$json) { echo curl_error($ch); } curl_close($ch); $tempData = json_decode($json); print_r($tempData);<br> 

Output:

stdClass Object ( [error] => Missing key, signature and nonce parameters )
