• Code Example in Java to generate sig value:

   
	public class UrlParam implements Comparable<UrlParam> {
		String name;
		String value;
		public UrlParam(String name, String value) {
			this.name = name;
			this.value = value;
		}
		public int compareTo(UrlParam o) {
			return name.compareTo(o.name);
		}
	}

	String secretKey = "yourSecretKey";
	String apiKey    = "yourApiKey";
	long requestId   = System.currentTimeMillis();
        
	UrlParam param1 = new UrlParam("sk_user_id", "1235678");
	UrlParam param2 = new UrlParam("session_id", "KJDFSKDH134");
	String signature = generateSigValue(param1, param2);  // GENERATED SIG VALUE

	public  String generateSigValue(UrlParam... params)
	{

		// Add API key
		UrlParam[] paramsWithApiKey = new UrlParam[params.length + 1];
		paramsWithApiKey[0] = new UrlParam("key", apiKey);
		System.arraycopy(params, 0, paramsWithApiKey, 1, params.length);
		
		// sort params
		Arrays.sort(paramsWithApiKey);
		
		// Add sig and rid
		UrlParam[] paramsWithSigRid = new UrlParam[paramsWithApiKey.length + 2];
		System.arraycopy(paramsWithApiKey, 0, paramsWithSigRid, 0, paramsWithApiKey.length);
		paramsWithSigRid[paramsWithApiKey.length] = new UrlParam("sig", secretKey);
		paramsWithSigRid[paramsWithApiKey.length + 1] = 
                                     new UrlParam("rid", String.valueOf(requestId++)); 
		
		
		// concatenate parameter values
		StringBuilder sb = new StringBuilder();
		for (UrlParam param : paramsWithSigRid) {
			String value = param.value;
			if (value != null && !value.isEmpty()) {
				sb.append(value);
			}
		}
		
		// MD5 parameter values
		String toSigValues = sb.toString();	
		MessageDigest md = MessageDigest.getInstance("MD5");
		try {
			md = MessageDigest.getInstance("MD5");		
		} catch (Exception e) {
		
		}
		md.update(toSigValues.getBytes());
		byte[] digest = md.digest();

		StringBuffer hexString = new StringBuffer();

		for (int i = 0; i < digest.length; i++) {
			toSigValues = Integer.toHexString(0xFF & digest[i]);
			if (toSigValues.length() < 2) {
				toSigValues = "0" + toSigValues;
			}
			hexString.append(toSigValues);
		}
		return hexString.toString();
	 }

Note: This value will change after we analyze the API traffic data, growth, and performance. It will also change in the future once we introduce the pricing model for the API.
