Hi,
Thank you for reaching out to the Google Ads API support team.
Upon reviewing your concern, I understand that you are encountering an UNSUPPORTED_VERSION error while performing API requests for your account. You mentioned that you changed from version 14 to 16 but are still getting the same error. Please note that v16 is also deprecated and will sunset by January 2025. I would recommend upgrading to v17, the latest version of the Google Ads API, which enables you to use the new features introduced in each release. For information regarding Deprecation and sunset, you can refer to this link.
