[Agapito78]

Hi, I'm getting the error message below when trying to update a product. I'm able to create a product but when I try to update I get the error below

Code: $clientID = "ck_9826vaba5e42366227f19y389ef456c92342c36d241g"; $clientSecretKey ="cs_9826vaba5e42366227f19y389ef456c92342c36d241g" $options = array ( 'debug' => true, 'return_as_array' => false, 'validate_url' => false, 'timeout' => 30, 'ssl_verify' => 2 );

$store_url = "https://www.twss.com.br/store";

$wc_api = new WC_API_Client ( $store_url, $clientID, $clientSecretKey, $options );
$retWoo = $wooapi->products->update("4555",array( 'title' => 'Yet another test product' ));
