Login to the application and navigate to /connector/client
Create new client and generate Client ID and Client secret
Once you have created the client, you may request an access token by issuing a POST request to the /oauth/token route
$http = new GuzzleHttp\Client;
$response = $http->post('https://erp.dstadvertising.com/oauth/token',
[
'form_params' => [
'grant_type' => 'password',
'client_id' => 'client-id',
'client_secret' => 'client-secret',
'username' => 'taylor@laravel.com',
'password' => 'my-password',
'scope' => '',
],
]);
