Backend:

```auto

        return view('student.course', compact('zoomSignature', 'zoomMeetingId'));
    }

    private function generate_signature($api_key, $api_secret, $meeting_number, $role)

        //build the headers
        $headers = ['alg' => 'HS256', 'typ' => 'JWT'];
        $headers_encoded = $this->base64url_encode(json_encode($headers));

        //build the payload
        $payload = [

            'role' => $role,
            'iat' => $now->timestamp,
            'exp' => $now->addSeconds(1800)->timestamp
        ];
        $payload_encoded = $this->base64url_encode(json_encode($payload));

        //build the signature
        $signature = hash_hmac('SHA256', "$headers_encoded.$payload_encoded", $api_secret, true);
        $signature_encoded = $this->base64url_encode($signature);

        $token = "$headers_encoded.$payload_encoded.$signature_encoded";

        // Log::debug($token);
        return $token;
    }

    private function base64url_encode($data)
    {
        return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');
    }
}

**Additional context**  
Already tried following the PHP signature generator mentioned at [Generate Signature](https://marketplace.zoom.us/docs/sdk/native-sdks/web/signature) which returns an invalid signature error. Then refactored backed signature logic to the above referring [SDK Authorization](https://marketplace.zoom.us/docs/sdk/native-sdks/auth/#generate-the-sdk-jwt)
