ACCESS THE VARIABLE FROM THIS STRING

I make ca curl request to paystack api and here is the result I get

{ "status": true, "message": "Authorization URL created", "data": { "authorization_url": "https://checkout.paystack.com/91ahxcwbqvfefrr", "access_code": "91ahxcwbqvfefrr", "reference": "4ge2lj12g1" } }

How do I access the value for status and authorization_url? Here is what I have tried

 //execute post
 $result = curl_exec($ch);

echo $result['status'];

Error: Illegal string offset 'status' then I tried

      //execute post
        $result = curl_exec($ch);

        $responds = json_decode($result, true);

        echo $responds;

ErrorException Array to string conversion

Here is the full code

        $url = "https://api.paystack.co/transaction/initialize";

        $fields_string = http_build_query($data);

        $ch = curl_init();
  
        //set the url, number of POST vars, POST data
        curl_setopt($ch,CURLOPT_URL, $url);
        curl_setopt($ch,CURLOPT_POST, true);
        curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            "Authorization: Bearer " . getenv('PAYSTACK_SECRET_KEY'),
            "Cache-Control: no-cache",
        ));

          //So that curl_exec returns the contents of the cURL; rather than echoing it
        curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); 
          
        //execute post
        $result = curl_exec($ch);
