I am very new to servicenow and if I need to post this somewhere else please let me know. I am trying to create an OAuth code flow from an external service. This is how I have my servicenow application registry configured:
When I make the OAuth code grant flow request everything works as expected and I receive the authorization code. However, when I grant type authorization_code request I am redirected to https://dev#.service-now.com/oauth_login.do URL and I do not receive an access token as expected.
I am making this request from a Laravel PHP controller so there is no user to complete the login page.
Here is a snippet of my PHP code:
$fields = [
'grant_type' => 'authorization_code',
'client_id' => $fields->client,
'client_secret' => $fields->secret,
'code' => $q['code'],
'redirect_uri' => "$hostUrl/externalurl/oauth/response",
'response_type' => 'code',
'state' => $q['state']
];
//url-ify the data for the POST
$fields_string = http_build_query($fields);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'cache-control: no-cache',
'content-type: application/x-www-form-urlencoded'
));
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
