I am getting a 401 on Guzzle 4.2 and the same setup works on Postman. Code below.
// Create a client with a base URL $client = new GuzzleHttp\\Client([\'
$response = $client->get('GET', 'cloud.feedly.com/v3/streams/contents?streamId=user/user-id/category/global.all&count=1', ['auth' => ['YOUR_USERNAME', 'YOUR_PASSWORD']]);
The 401 error means you should authenticate yourself with a valid username and password
Regards
