I was trying to send sms with infobip with following way:

https://www.infobip.com/docs/api/channels/sms/sms-messaging/outbound-sms/send-sms-message

and i was also trying to get the delivery report with webhook so that i can store the log on my database

https://www.infobip.com/docs/api/channels/sms/sms-messaging/logs-and-status-reports/receive-outbound-sms-message-report

I have send the request in following way:

public function singleSMS($contacts,$sender,$communication)
    {
        $destinationsMapped = [];
        foreach ($contacts as $contact) {
          $destinationsMapped[] = ['to' => (string) $contact->contact_number];
        }

        $data = [
            'bulkId' => $communication->id,
            'messages' => [
                [
                    'destinations' => $destinationsMapped,
                    'from' => $sender->sender_number,
                    'text' => $communication->communication_text
                ]
            ],
            'notifyUrl' => 'https://test_url.com/infobip/sms/response',
            'tracking' => [
                'track' => 'SMS',
                'type' => 'MY_CAMPAIGN'
            ]
        ];
       
         $curl = curl_init();

            curl_setopt_array($curl, array(
                CURLOPT_URL => 'https://api.infobip.com/sms/2/text/advanced',

                CURLOPT_RETURNTRANSFER => true,
                CURLOPT_ENCODING => '',
                CURLOPT_MAXREDIRS => 10,
                CURLOPT_TIMEOUT => 0,
                CURLOPT_FOLLOWLOCATION => true,
                CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
                CURLOPT_CUSTOMREQUEST => 'POST',
                CURLOPT_POSTFIELDS => json_encode($data),
                CURLOPT_HTTPHEADER => array(
                    'Authorization: App 7447',
                    'Content-Type: application/json',
                    'Accept: application/json'
                ),
            ));

            $response = curl_exec($curl);
            Log::info(json_encode($data));
            curl_close($curl);

            return $response;
    }

I have stored the response from infobip in following way:

public function infobipResponse(Request $request)
    {
        $json = file_get_contents('php://input');

        $data = json_decode($json, true);

        Log::info(json_encode($responseArray));
        if ($data === null)
        {
            return response()->json(['error' => 'Invalid JSON data'], 400);
        }
        if (!isset($data['results']) || !is_array($data['results'])) 
        {
            return response()->json(['error' => 'Missing or invalid results data'], 400);
        }
        foreach ($data['results'] as $result) 
        {
            DB::table('communication_logs')->insert([
                'msgCount' => $result['smsCount'],
                'smscCost' => $result['price']['pricePerMessage'],
                'no_of_contacts' => $result['status']['id'],
                'communication_id' => $result['bulkId'],
                'created_at' => $result['doneAt']
            ]);
        }
        return response()->json(['status' => 'success']);
    }

Route:

Route::controller(InfobipController::class)->group(function() {
      Route::post('infobip/sms/response','infobipResponse');
    });

Sms send is OK, sms is sent to mobile successfullly. But the problem is I can’t get the delivery report response to notifyUrl.
Why’s that? What’s wrong with my above functionality?
