Hi,
Thank you for reaching out to the Google Ads API support team.
Yes, you can create campaigns for accounts that you manage, as well as for accounts client by your sub-managers. From the same page, you can also quickly change a campaign’s budget, status, and name or jump directly to the campaign to make other changes. For more details, you may refer to this
article.
Additionally, it is not always mandatory that a child account must specifically belong to a manager account in a hierarchy.
I hope this information is helpful. Let us know if you have any further questions.
