Creating promotionLine in Product Ads using AdGroupAdService

[pidus]

Hi,

I am trying add a promotionLine to an existing product-ad using Adwords API  v201109 . My outgoing and incoming soap's are listed below (with intentionally obfuscated data) but it is still not resulting in creation of a promotionLine. Any ideas?

Hi,

The Ads objects (ProductAds, TextAds, ImageAds, etc) are immutable in the system by design. Instead you need to delete and re-create your Ad.

Best,
