and this is my code

@mosamater32 hope you will be fine.

First thing please format the code section in your above post.

You need to create MeetingSDK App & then get SDK Key & Secret to generate the signature.

If you are using NodeJS then here is a sample of how to generate the signature.

const KJUR = require('jsrsasign');

function generateSignature(meetingNumber, role) {
    const iat = Math.round(new Date().getTime() / 1000) - 30;
    const exp = iat + 60 * 60 * 2

    const oHeader = {
        alg: 'HS256',
        typ: 'JWT'
    }

    const oPayload = {
        sdkKey: process.env.ZOOM_APP_KEY,
        mn: meetingNumber,
        role: role,
        iat: iat,
        exp: exp,
        appKey: process.env.ZOOM_APP_KEY,
        tokenExp: iat + 60 * 60 * 2
    }

    const sHeader = JSON.stringify(oHeader)
    const sPayload = JSON.stringify(oPayload)
    const signature = KJUR.jws.JWS.sign('HS256', sHeader, sPayload, process.env.ZOOM_APP_SECRET)

    return signature;
}

module.exports = {
    generateSignature
}

here is a guide how to migrate from JWT app to Meeting SDK app

important: if you create a new Meeting SDK app

and here an example, how to create the signature on your php server
