## Properties
**ad_type** | **AdType** | (enum: single) |
**ad** | **serde_json::Value** | The persisted Ad document. |
**message** | **String** | |
**warnings** | Option<**Vec<String>**> | Present when Meta created the ad set differently from the request: Meta kept the ad set without the requested `whatsappPhoneNumber` in its promoted_object (the ads still carry it on their WhatsApp button), or the ad set joined a CBO campaign (`existingCampaignId`) whose own bid strategy applies, so a different `bidStrategy` or a `roasAverageFloor` that strategy cannot take was not applied. | [optional]
