Coinbase fetchBalance() missing some coin balances

See original GitHub issue

OS: Linux
Programming Language version: PHP 7.3
CCXT version: 1.38.13

$id = "\\ccxt\\kucoin";
$exchange = new $id();
$exchange->apiKey = "XXXX"; // testing API key
$exchange->secret = "YYYY";
$exchange->enableRateLimit = true;

for($balance : $exchange->fetchBalance()) {
	print_r($balance["total"]);
}

Error: Some coin balances are missing (e.g. LINK, ZRX). CCXT returns:

Array
(
[BAL] => 0
[REN] => 0
[UNI] => 17.79959553
[CELO] => 2.83389059
[YFI] => 0
[UMA] => 0
[REPV2] => 0

[ATOM] => 7.29854
[ZEC] => 0
[NMR] => 0
[XLM] => 135.5708257
)

And here is a screenshot from Coinbase dashboard (ZRX, LINK and more missing from CCXT output):

The API key was made properly, all balances are enabled (sorry for bad quality):

I tried with another Coinbase account which only holds ZRX and LINK, but it worked well. It looks like when there are many coins, not all get properly parsed or something like that?

Lastly, here is the verbose output:

@kroitor this is perfect! I was able to make it work using your suggested code.

@c0dehunter the problem is related to the way coinbase serves the account balances, since it’s not a conventional exchange (as opposed to coinbasepro or coinbaseprime). The support for coinbase in CCXT is rudimentary, we added it because the users wanted it, but we don’t expect it to comply with conventional exchange API standards. So, working with Coinbase from CCXT will require some custom code. In this particular case you will need to traverse the balances:

https://github.com/ccxt/ccxt/blob/master/examples/php/coinbase-fetch-all-balances.php

<?php

$root = dirname (dirname (dirname (__FILE__)));

include $root . '/ccxt.php';

date_default_timezone_set ('UTC');

$exchange = new \ccxt\coinbase(array(
    // 'apiKey' => 'YOUR_API_KEY',
    // 'secret' => 'YOUR_SECRET',
    "apiKey" => "GgYYlBYhyO08R75Q",
    "secret" => "Y2890ISIaEsHZLi80QaG2JoKly3jK6qR",
    // 'verbose' => true, // uncomment for debugging
    // https://github.com/ccxt/ccxt/wiki/Manual#rate-limit
    'enableRateLimit' => true, // rate-limiting is required by the Manual
));

$exchange->load_markets ();

// $exchange->verbose = true; // uncomment for debugging

$result = array();
$params = array();
$loop = true;
do {
    $balance = $exchange->fetch_balance($params);
    $pagination = $exchange->safe_value($balance['info'], 'pagination');
    if ($pagination === null) {
        $loop = false;
    } else {
        $next_starting_after = $exchange->safe_string ($pagination, 'next_starting_after');
        if ($next_starting_after !== null) {
            $params['starting_after'] = $next_starting_after;
        } else {
            $loop = false;
        }
    }
    echo $exchange->iso8601($exchange->milliseconds()) . "\n";
    $result = $exchange->deep_extend($result, $balance);
} while ($loop);

echo "======================================================================\n";
var_dump($result);

?>
