Podium stores your data as objects containing JSON compatible key-value pairs. You can think of Podium data storage as your app's cloud database where each object is a row in that database.

Using Podium Data Storage you can perform GET and QUERY operations.

To get your nonce hash, you must create a hash-based message authentication code (HMAC) by SHA256 hashing your URL up to this point using your private key. In this example,

Public Key: KcIRoGC3WHdR29JhfN1cg
Private Key: 2ZWTeKi47fZwVPp6ds5nxUtvsvS3Hm2FLkadbcA8U2

The resulting hash is fd1552a4ce51aefe819c7196760b672f4a8c3f76c454ece62b9985c8bec40c1e

For PHP:

<?
    // set variables
    $public_key = 'KcIRoGC3WHdR29JhfN1cg';
    $private_key = '2ZWTeKi47fZwVPp6ds5nxUtvsvS3Hm2FLkadbcA8U2';
    $time = time();
    
    // set data var to the URL you have built so far
    $data = 'https://podium.io/api/v1/events/?request=close &lat=37.421641&long=-122.085502&public_key='.$public_key.' &date='.$time;
	
    // generate hash
    $hash = hash_hmac('sha256', $data, $private_key);
    
?>

For JavaScript (Appcelerator):

Note: You must include a third party script to generate the hmac hash. The following code uses crypto-js, hosted on google code, available here.

    // include cryptography script
    Ti.include("../../includes/CryptoJS_v3.1.2/rollups/hmac-sha256.js");
    
    // set variables
    var url = 'https://podium.io/api/v1/events/';
    var public_key = 'KcIRoGC3WHdR29JhfN1cg';
    var private_key = '2ZWTeKi47fZwVPp6ds5nxUtvsvS3Hm2FLkadbcA8U2';
		 		
    var currentTime = new Date();
    var time = Math.round((currentTime.getTime())/1000);
 		
    var data = url + '?request=close ⪫=37.421641&long;=-122.085502 &public;_key=' + public_key + '&date;=' + time;
    var hash = CryptoJS.HmacSHA256(data, private_key);

For Lua (Corona):

    -- set variables
    local public_key = "KcIRoGC3WHdR29JhfN1cg"
    local private_key = "2ZWTeKi47fZwVPp6ds5nxUtvsvS3Hm2FLkadbcA8U2"
    local t = os.date( '*t' )
    local time = os.time( t ) 
    
    -- set data var to the URL you have built so far
    local data = "https://podium.io/api/v1/events/?request=close &lat=37.421641&long=-122.085502&public_key=" .. public_key .. " &date=" .. time
    
    -- generate hash
    local crypto = require "crypto"
    local hash = crypto.hmac( crypto.sha256, data, private_key )
