Mutating Resources

The Google Ads API provides a few different ways for mutating resources, depending on your use case. Each resource has a corresponding service that lets you specify mutate operations for that specific resource type. For example, the Campaign resource has a corresponding CampaignService.MutateCampaigns endpoint for mutating campaigns.

Another option is the GoogleAdsService.Mutate endpoint, which essentially wraps a series of individual mutate calls on the resource services and provides the following benefits:

• Grouped actions across different resource services. Normal calls can only execute operations against a single resource service.
• Temporary resource names. Combine operations to create an entity and its child entities in a single request.

With these two properties, you can use GoogleAdsService.Mutate to, for example, create an entire campaign structure only if every step along the way succeeds.

Key Point: Generally, cross-account mutating is not allowed; an account cannot mutate objects that it didn't create, unless it is the manager of the client that created the object.
