Create Ad Extension

Fallback Microsoft Ads ad extension create tool for types with no dedicated operation. Use this only when no focused operation covers the extension you need; if one exists, such as microsoft_ads_create_sitelinks or microsoft_ads_create_callouts, always use that dedicated operation instead. It takes a raw Microsoft ad extension object carrying a Type, which reaches the types that have no operation of their own: call, location, price, promotion, app, review, action, flyer, logo and filter link. Optionally attaches the new extension to campaigns or ad groups in the same run. The object is sent to Microsoft unchanged, so a rejection is Microsoft validating the payload rather than a Markifact fault: check the required fields for that extension type and fix the object.

Inputs

Field	Type	Required	Default	Description
`account`	object or array of object or MicrosoftAdsAccountItem or string or integer	Yes	-	Select the Microsoft Ads account to create the ad extension in.
`extension`	object or string	Yes	-	The ad extension object, as JSON, exactly as the Microsoft Advertising Campaign Management API version 13 defines it, sent unchanged to its AddAdExtensions operation. It must carry a Type naming one of: ActionAdExtension, AppAdExtension, CallAdExtension, CalloutAdExtension, FilterLinkAdExtension, FlyerAdExtension, ImageAdExtension, LocationAdExtension, LogoAdExtension, PriceAdExtension, PromotionAdExtension, ReviewAdExtension, SitelinkAdExtension, StructuredSnippetAdExtension. For example a call extension is {“Type”: “CallAdExtension”, “CountryCode”: “GB”, “PhoneNumber”: “01420 561661”, “IsCallOnly”: false}. The Type value is also the name of Microsoft’s data object for that extension, so searching their Campaign Management reference for that name gives the exact fields and which are required. Id, Status and Version are set by Microsoft and are rejected on create.
`level`	string or SelectableOption	No	-	Optionally attach the new extension straight away: ‘ACCOUNT’, ‘CAMPAIGN’ or ‘AD_GROUP’. Leave empty to create it unattached and attach it later with microsoft_ads_apply_ad_extension_to_entities.
`campaign_ids`	array of string or SelectItem	No	-	Campaigns to attach to. Required when level is CAMPAIGN.
