This is just a collection of functions written in different languages to create an access_token using your client credentials. It is meant to help people who are starting now with the API.
There are very good community created libraries that already deal with this OAuth flow and all the endpoint requests. Use this only if you want to create your own implementation or understand better how it works.
PHP
function createAccessToken($apiKey, $apiSecret, $region = 'us') {
$curl_handle = curl_init();
try {
curl_setopt($curl_handle, CURLOPT_URL, "https://$region.battle.net/oauth/token");
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, ['grant_type' => 'client_credentials']);
curl_setopt($curl_handle, CURLOPT_USERPWD, $apiKey . ':' . $apiSecret);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_handle, CURLOPT_HTTPHEADER, ['Content-Type: multipart/form-data']);
$response = curl_exec($curl_handle);
$status = curl_getinfo($curl_handle, CURLINFO_HTTP_CODE);
if ($status !== 200) {
throw new Exception('Failed to create client_credentials access token.');
}
return json_decode($response)->access_token;
} finally {
curl_close($curl_handle);
}
}
GScript (Google docs/spreadsheets)

};
var url = 'https://' + region + '.battle.net/oauth/token';
var response = UrlFetchApp.fetch(url, options);
return JSON.parse(response.getContentText()).access_token;
}
