Currently, campaign goals are not supported through the AdWords API. However, creating of Search Campaign is supported and you can still implement your marketing strategies through the API by using the
Remarketing,
Bidding and/or
Targeting. To create a search campaign, you have to set the
advertisingChannelType field to
SEARCH. You may refer to this
guide for more information on creating campaigns which also includes complete
sample code.
