How Can I increase the expiry time of Spotify token?

Question

Please advice how can I increase token expiry time While fetching data using spotify web API \"https://accounts.spotify.com/api/token\"

Answer 1

Access tokens expire after one hour. This expiry time is set on Spotify's side and can't be changed by the client.

You can refresh an access token if you're retrieving it using the Authorization Code flow. (The refresh token is practically valid forever, or until it has been manually revoked.)
