How to perform Digest Authentication With Requests

$user = 'myusername';
$pass = 'mypass';
$BaseApiUrl     = 'myurl';

$headers = array('Accept' => 'application/json');
$options = array('auth' => new Requests_Auth_Basic(array($user, $pass)));
$request = Requests::get($BaseApiUrl, $headers, $options);
var_dump($request->status_code);
var_dump($request->body);

This is my code it gives error
int(401) string(28) "HTTP Digest: Access denied. "

You have
Basic/Digest Authentication

please provide step for Digest Authentication

Review the issue's PHP example, especially Requests_Auth_Basic and the Requests::get call, and inspect the repository's existing authentication documentation or examples. Clarify whether Digest Authentication is supported and document the correct usage if the project provides it; done means a newcomer can follow the documented steps without receiving the reported 401 response.
