Hiii,
I’m also having a problem with authentication. I got the error during generating the oauth token. Can you tell me what I’m doing wrong?

Please check below code:-

require_once (‘lib/hhb_.inc.php’);
$hc = new hhb_curl ( 'https://api.yelp.com/oauth2/token', true );$hc->setopt_array ( array (
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => http_build_query ( array (
‘grant_type’ => ‘client_credentials’,
‘client_id’ => ‘XXXXXXX’,
‘client_secret’ => ‘XXXXXXX’
) )
) );
$hc->exec ();$result = $hc->getStdOut ();

if(result) { data = json_decode($result); print_r($data);
}

[error] => stdClass Object
(
[code] => OAUTH_TOKEN_ENDPOINT_DEPRECATED
[description] => The oauth2 token endpoint has been deprecated and removed; you must use your API key for authentication instead. Please see https://www.yelp.com/developers/documentation/v3/authentication#where-is-my-client-secret-going for info & migration steps
)

Please let me know if you have any solution for this type of error in case of accessing the token…
