Hi Dhruv,
Thank you for reaching out! Yes, you can remove a child account via Google Ads API by using
MutateCustomerManagerLink within
CustomerManagerLinkService. If you set the Update operation with status INACTIVE, you can terminate the link between the manager and the child account.
Let me know if you have any additional questions.
Regards,
Danica Calusin, Google Ads API Team
