Hi Latha, Access tokens have an expiration time <https://developers.google.com/adwords/api/docs/guides/authentication#access_token_expiration>. If you are using the token after it has expired, you would get a OAUTH_TOKEN_INVALID error. You should then use the refresh token to get a new access token or to refresh an expired token. If you are using any of the client libraries <https://developers.google.com/adwords/api/docs/clientlibraries>, by default, the expired access token gets automatically refreshed.
I hope this helps.
