Manuel Moreira this sounds like a different issue than an expired JWT. For reference, below is what a working JWT looks like for my app. Perhaps you can compare yours to it to confirm you have the right header, field names, and data types.

Manuel Moreira did you try parsing your JWT and confirming it is properly formed? Try copy/pasting your JWT into https://jwt.io to make sure it is valid.

Check that your token is not expired. The "exp" field is specified in seconds since the UNIX epoch, so a token with exp = 12345678 expired sometime around February 1971. In TypeScript with the jsonwebtoken library, you could do something like:

import jwt, { SignOptions } from "jsonwebtoken";
const header = {
  alg:"HS256",
  typ:"JWT", 
  kid:zenDeskKid,
};

const options: SignOptions = {
  header,
  expiresIn: 60 * 60 * 6, // <-- this will convert to UNIX epoch time
};

const payload = {
  scope:"user",
  name: ...,
  email: ... ,
  external_id: ...,
};

var token = jwt.sign(payload, zenDeskSecret, options);
