Laravel - How to pass variable as parameter to external API using guzzle - laravel

Question

I am using Laravel-5.8 and Guzzle to consume an external api:
public function index()
{
try{
$myparam = 'JKK123';
$client = new Client();
$res = $client->request('GET','https://examplet/tracking/$myparam', [
'query' => ['key' => 'jkkffd091']
])->getBody();
$geoLocation = json_decode($res->getContents(), true);
$currentLocation = collect($geoLocation)->sortByDesc(function ($data) {
return Carbon::parse($data['Timestamp'])->format('d-m-Y h:i:s');
})->first();
$currentLocationFilter = explode(',', $currentLocation['current_asset_position_coord'] ?? '');
dd($currentLocationFilter);
return view('index', [
'currentLocation' => $currentLocation,
'currentLocationFilter' => $currentLocationFilter,
'geoLocation' => $geoLocation
]);
}catch (Exception $exception) {
Log::error($exception);
return back();
}
}
I am trying to pass the variable as parameter to the API. I didn't put it directly because it changes. I just tried to test.
When I did this as shown in the code above
$res = $client->request('GET','https://examplet/tracking/$myparam', [ ...
and then
dd($currentLocationFilter);
I got:
array:1 [▼
0 => ""
]
But when I put the value directly,
$res = $client->request('GET','https://examplet/tracking/JKK123', [
I got the required result:
array:2 [▼
0 => "2.1234565432145"
1 => "1.7864321249555"
]
How do I paa the variable as parameter into the external API?
Thanks

Use double quotes for executing variable like this:
$res = $client->request('GET',"https://examplet/tracking/{$myparam}", [...
