I am using Google Drive API to get the list of files on my google drive. I've got it working by getting an access token, client id and client secret in google cloud platform. My issue is, the token expires in 3600. I've tried this endpoint, https://www.googleapis.com/oauth2/v4/token

and put this in the request body,

{
  "client_id": "client_id",
  "client_secret": "client_secret",
  "refresh_token": "access_token",
  "grant_type": "refresh_token"
}

but is only returning

{
    "access_token": "new_access_token",
    "expires_in": 3552,
    "scope": "https://www.googleapis.com/auth/drive.file https://www.googleapis.com/auth/drive",
    "token_type": "Bearer"
}

which doesn't refresh the token life.

is there anything I'm missing?

I am using it on postman first so that I can know it's working properly.

any help is appreciated.

    Access tokens expire after an hour this is intentional. I believe with postman you are going to have to manually request a new access token when it expires. I don't think its going to automatedly refresh it for you. Have a look at this if it doesnt help let me know and i will give it ago.

Access tokens expire after a set time, and you need to make a call to request a new access token, using the refresh token you received. Generally, refresh tokens last longer and don't expire in a while, while access tokens are short lived.

This link is to the Google API doc: https://developers.google.com/identity/protocols/oauth2/web-server#offline

This is an SO similar question with useful information, and a useful answer: How to generate access token using refresh token through google drive API?

Basically, you can make an API call from postman to request for a new access token every time you need one (and use it in Postman for the call you need to make)

Turns out, you need to get refresh token from https://developers.google.com/oauthplayground/. You also need to authorize the redirect uri from Google Cloud Platform. Thanks for the guides. really helped a lot.
