Null data

[GiuniGiorgio01]

Hello, I wanted to report this fact, I'm doing everything via php, I followed the tutorial for php, I report the code:

$curl = curl_init();

curl_setopt_array( $curl, array( CURLOPT_URL => 'https://api.countrystatecity.in/v1/countries', CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => array( $this::$apiKey . ': ' . $this::$apiValue, ), ));

where $apiKey is 'X-CSCAPI-KEY' and apiValue is my key,

when I get the array response with: $response = json_decode( curl_exec( $curl ), true);

it gives me null, I was thinking that the problem is the api key I received,

When I copy paste the key from the email at the and of the character sequence there is an additional space, I thought that maybe its part of the key too?, in both ways, with or without it doesn't work

I've also tried to write the curl_setopt_array like this:

curl_setopt_array( $curl, array( CURLOPT_URL => 'https://api.countrystatecity.in/v1/countries', CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => array( 'X-CSCAPI-KEY: my_key', ), ));

neither this way it returns me any data...

what can I do?
