Sending [] in URL Query Params get encoded

[Alex Richards]

I'm trying to use this library to interact with the Zendesk API. Using the following code, I'm requesting the Users endpoint with some query params in the URL ?role[]=agent&role[]=admin

However, when I have this code I get an error response back from Zendesk saying the params aren't correct.

Request to API

$req = Zttp::withHeaders([
    'Authorization' => 'Bearer MYTOKEN',
])->get('https://MYSUBDOMAIN.zendesk.com/api/v2/users.json?role[]=agent&role[]=admin');

dd($req->json());

Error from API

^ array:1 [▼
  "error" => array:2 [▼
    "title" => "Invalid attribute"
    "message" => "You passed an invalid value for the role attribute. Invalid parameter: role must be a string from api/v2/users/index"
  ]
]

If I look at the URL which Zttp actually sends it appears as:
https://MYSUBDOMAIN.zendesk.com/api/v2/users.json?role%5B0%5D=admin&role%5B1%5D=agent

I have also tried using:

    $req = Zttp::withHeaders([
        'Authorization' => 'Bearer MYTOKEN',
    ])->get('https://MYSUBDOMAIN.zendesk.com/api/v2/users.json', [
        'role' => 'admin',
        'role' => 'agent',
    ]);

and

    $req = Zttp::withHeaders([
        'Authorization' => 'Bearer MYTOKEN',
    ])->get('https://MYSUBDOMAIN.zendesk.com/api/v2/users.json', [
        'role[]' => 'admin',
        'role[]' => 'agent',
    ]);

Using this approach, Zendesk get's only one of the parameters.
Does anyone have any suggestions how I can get this working? Via the query params is the only way Zendesk will accept.

Have you tried sending the roles as an array instead?

$req = Zttp::withHeaders([
    'Authorization' => 'Bearer MYTOKEN',
])->get('https://MYSUBDOMAIN.zendesk.com/api/v2/users.json', [
    'role' => ['admin',  'agent'],
]);

Those last two examples won't work because they're defining duplicate keys on a PHP array.
