Hi Sendwebpush services,
Thank you for reaching out to the Ad Manager API support team, this is Madhushree.
Upon checking, I am afraid that It is not possible to add a subdomain to a site through the Ad Manger API, It is available only in Ad Manager 360(UI) as of now. However, I have raised a request to add this feature in the API with the rest of our team, please follow our
blog post and
release notes for updates.
Regards,
