wp_remote_get and url parameters - php

Question

I'm trying to use an API with wp_remote_get which requires pagination.
Currently, my WordPress plugin calls the API the following way
$response = wp_remote_get( "https://api.xyz.com/v1/products" ,
array( 'timeout' => 10,
'headers' => array(
'Authorization' => 'Bearer xyz',
'accept' => 'application/json',
'content-type' => 'application/json'
)
));
$body = wp_remote_retrieve_body( $response );
return json_decode($body);
Now, if I change the URL from /products to /products?page_size=5&page=2, which works fine in Postman and other programs, i am not getting a response. Why is that? I checked the API documentation of wp_remote_get but am not figuring it out.

Typically you use curl command to GET the response but I would recommend you to use Guzzle PHP HTTP client to make your calls if you are making multiple of them.
You will have to compser install Guzzle.
composer require guzzlehttp/guzzle:^7.0
I am expecting that the autoloader class is loaded.
Once installed and you can use it as follows.
use GuzzleHttp\Client;
$client = new Client(
[
// Base URI is used with relative requests.
'base_uri' => https://api.xyz.com/v1/,
// You can set any number of default request options.
'timeout' => 10.0,
]
);
$url = 'products';
$payload = array(
'page_size' => 5,
'page' => 2,
);
try {
$request = $client->request(
'GET',
$url,
[
'query' => $payload,
]
);
$status = $request->getStatusCode();
$response = json_decode( $request->getBody() );
if ( 200 === $status ) {
echo $response;
}
} catch ( Exception $e ) {
echo $e;
}
You can change the $url and $payload for other queries.
