Production oauth token expires after one hour

[boas8087]

I tried getting fresh token from my application but failed how can I get a oauth token from my python based application or longer the duration of my oauth tokens?

The OAuth access tokens are good for two hours.

If getting an application token (client_credential) for accessing public data, you would need to mint a new token every two hours.

If getting a user token for private data (authorization_code), the authentication process will return both a 2-hour access token and an 18-month refresh token that is linked to the user account. When the 2-hour token expires, use the refresh token to mint another 2-hour token.
