Hello Hari, Could you try and regenerate the refresh token again by following this guide <https://developers.google.com/adwords/api/docs/guides/authentication>? You can refer to the example from the Java client library <https://github.com/googleads/googleads-java-lib> for generating the credentials. Additionally, could you confirm if you're generating the refresh token in every API call? If so, please note that there is a limit <https://developers.google.com/identity/protocols/OAuth2#expiration> of 50 refresh tokens per user per account. If you're trying to generate a refresh token above the specified limit, they will be invalidated. Let me know if that works for you.
