GetKeywordCategories Service Operation - Ad Insight

Gets the keyword categories to which the specified keywords belong.

Request Elements

The GetKeywordCategoriesRequest object defines the body and header elements of the service operation request. The elements must be in the same order as shown in the Request SOAP.

Request Body Elements

Element Description Data Type
Keywords An array of keywords for which you want to determine the possible keyword categories that each keyword belongs to. The array can contain a maximum of 1,000 keywords, and each keyword can contain a maximum of 100 characters. string array
Language The language in which the keywords are written. You must set this element to English. string
MaxCategories The number of categories to include in the results. The maximum number of categories that you can request is 5.

The default is 5.
PublisherCountry The country code of the country/region to use as the source of the category data.

You must set this element to US.

Request Header Elements

Element Description Data Type
AuthenticationToken The OAuth access token that represents a Microsoft Account user who has permissions to Bing Ads accounts. string
CustomerAccountId The identifier of the account that owns the entities in the request. This header element must have the same value as the AccountId body element when both are required. string
CustomerId The identifier of the customer that contains and owns the account. If you manage an account of another customer, you should use that customer ID instead of your own customer ID. string
DeveloperToken The developer token used to access the Bing Ads API. string
Password The Bing Ads managed user's sign-in password. string
UserName The Bing Ads managed user's sign-in name. You must not set this element to a Microsoft account or email address. string


The UserName and Password header elements are deprecated. In future versions of the API, Bing Ads will transition exclusively to Microsoft Account (email address) authentication. For more information, see Authentication with OAuth. UserName and Password are still required for Bing Ads managed credentials, but they are not applicable for Microsoft account authentication. To authenticate a Microsoft account, use the AuthenticationToken] header instead of UserName and Password.


The CustomerAccountId and CustomerId are required for most service operations, and as a best practice you should always specify them in the request.

Response Body Elements

Element Description Data Type
