Hi,

I want to create a signature using PHP code from my back end. As per the documentation, I’m using php code to generate signature

function generate\_signature ( $api\_key, $api\_secret, $meeting\_number, $role){  
$time = time() \* 1000 - 30000;//time in milliseconds (or close enough)  
$data = base64\_encode($api\_key . $meeting\_number . $time . $role);  
$hash = hash\_hmac(‘sha256’, $data, api\_secret, true); \_sig = $api\_key . “.” . $meeting\_number . “.” . $time . “.” . $role . “.” . base64\_encode(hash); return rtrim(strtr(base64\_encode(_sig), ‘+/’, '-_’), ‘=’);  
}

To this function we need to pass meeting number, for testing purpose I am getting meeting id from zoom api “[https://api.zoom.us/v2/users/{userId}/meetings](https://api.zoom.us/v2/users/%7BuserId%7D/meetings)” which is provided in the documentation “[https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meeting](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meeting)”. But how to get a meeting id dynamically using ZOOM SDK…?? Can someone please guide me. I am stuck with this from past one week.

Thank you.

Hey @wikikidslimited,

To get a meeting ID dynamically you need to use the [Create Meeting API](https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingcreate) along with the Web SDK. 🙂

You cannot do it directly with the Web SDK.

Thanks,  
Tommy
