16.1. KeywordEstimatorService Messages and Responses

The KeywordEstimatorService will provide traffic estimates for campaigns, AdGroups, and keywords. Table 16-1 shows the request objects, requests, and responses used for each of these types of estimates.

Table 16-1. Messages and responses for different kinds of estimates

AdWords object	Request object	Request message	Output response
Campaign	CampaignRequest	estimateCampaignList	CampaignEstimate
AdGroup	AdGroupRequest	estimateAdGroupList	AdGroupEstimate
Keyword	KeywordRequest	estimateKeywordList	KeywordEstimate

With an AdWords API client authenticated and instantiated, your code needs to:

1. Create a request object.

2. Provide the request object in a request message (which can contain multiple request objects).

3. Obtain estimate information from the response message.

These steps are illustrated in Figure 16-1.
