Hi İbrahim,
Thank you for reaching out to our support team.
However, my apologies as there is currently no way via the AdWords API to retrieve the remaining budget of your accounts. You may need to reach out to the Google Ads Product team for further assistance on how to get this information.
You can reach their team via the
? icon > Get help link while logged in to your Google Ads account, or you may also contact the product experts via the
Google Ads Help Community forum for guidance.
I hope this helps.
Best regards,
Peter
Google Ads API Team
