Make note of the Key ID which is required to generate client secret. Click on Download button to download your private key.

1. To generate client secret, use the following node js script

const fs = require("fs");
const jwt = require("jsonwebtoken");

const privateKey = fs.readFileSync("AuthKey_2AKZJ3L7T5.p8").toString(); //your downloaded private key path

const jwtToken = jwt.sign({}, privateKey, {
    algorithm: "ES256",
    expiresIn: "150d",
    audience: "https://appleid.apple.com",
    subject: "de.cidaas.testservice", //your service id
    issuer: "**********", //your 10-character Team ID which you obtained during app id creation
    header: {
        alg: "ES256",
        kid: "2AKZJ3L7T5" //your Key ID which you obtained during private key creation 
    }
});
console.log("secret:", jwtToken, "\n");

If you run this script, you will get your client secret, as shown below. Make note of this client secret.
