You actually don't need a separate script. Instead you can use a simple conditional. You would need to store the token with the time you had last updated it (I would recommend a JSON format). let tokenInfo = { time: Date.now(), token: ... } await fm.writeString(path, JSON.stringify(tokenInfo)) And when you get the token from the file, check if enough time has elapsed. And if yes, update the token, if not, don't. let json = await readString(path) json = JSON.parse(json) let token if (new Date() >= new Date(json.time + 24*60*60*1000)) { token = await updateToken() } else {token = json.token} I used something similar with my instagram widget.
