A Microsoft API that provides programmatic access to Microsoft Advertising to manage large campaigns or to integrate your marketing with other in-house systems.
Hello Balavenni
Thank you for using our Microsoft Advertising Learn Q&A Platform!
Thank you for your patience while we reviewed your question regarding ad group creation under a campaign with BudgetPaused status in the Microsoft Advertising API.
Across the Microsoft Advertising platform, there is normally no restriction preventing advertisers from creating ad groups under paused campaigns. Pausing a campaign (whether manually paused or system‑paused due to budget depletion) stops ad delivery but does not block structural changes such as adding ad groups.
Because of this, it would not make possible for the API to impose a restriction on creating ad groups only when a campaign is BudgetPaused, the expected behavior is that you should still be able to create ad groups in this scenario.
Although the official API documentation does not explicitly confirm support for this specific case, it also provides no indication of any restriction or error code tied to BudgetPaused that would block ad group creation. The documentation only explains what BudgetPaused means (i.e., ads will not serve due to depleted budget) but does not list structural limitations.
Additionally, the Campaign Management API documentation does not define any error codes or constraints that would prevent adding ad groups under campaigns in this status.
I hope above information was helpful for you! Our support teams are pleased to engage in more in-depth discussions about your account through phone, chat, or email to offer review assistance, please see our support page to reach out!
