News Search API upgrade guide


On October 30, 2020, the Bing Search APIs moved from Azure AI services to Bing Search Services. This documentation is provided for reference only. For updated documentation, see the Bing search API documentation. For instructions on creating new Azure resources for Bing search, see Create a Bing Search resource through the Azure Marketplace.

This upgrade guide identifies the changes between version 5 and version 7 of the Bing News Search API. Use this guide to help you identify the parts of your application that you need to update to use version 7.

Breaking changes


  • The endpoint's version number changed from v5 to v7. For example,

Error response objects and error codes

  • All failed requests should now include an ErrorResponse object in the response body.

  • Added the following fields to the Error object.

    • subCode—Partitions the error code into discrete buckets, if possible
    • moreDetails—Additional information about the error described in the message field
  • Replaced the v5 error codes with the following possible code and subCode values.

Code SubCode Description
ServerError UnexpectedError
Bing returns ServerError whenever any of the sub-code conditions occur. The response includes these errors if the HTTP status code is 500.
InvalidRequest ParameterMissing
Bing returns InvalidRequest whenever any part of the request is not valid. For example, a required parameter is missing or a parameter value is not valid.

If the error is ParameterMissing or ParameterInvalidValue, the HTTP status code is 400.

If the error is HttpNotAllowed, the HTTP status code 410.
RateLimitExceeded Bing returns RateLimitExceeded whenever you exceed your queries per second (QPS) or queries per month (QPM) quota.

Bing returns HTTP status code 429 if you exceeded QPS and 403 if you exceeded QPM.
InvalidAuthorization AuthorizationMissing
Bing returns InvalidAuthorization when Bing cannot authenticate the caller. For example, the Ocp-Apim-Subscription-Key header is missing or the subscription key is not valid.

Redundancy occurs if you specify more than one authentication method.

If the error is InvalidAuthorization, the HTTP status code is 401.
InsufficientAuthorization AuthorizationDisabled
Bing returns InsufficientAuthorization when the caller does not have permissions to access the resource. This can occur if the subscription key has been disabled or has expired.

If the error is InsufficientAuthorization, the HTTP status code is 403.
  • The following maps the previous error codes to the new codes. If you've taken a dependency on v5 error codes, update your code accordingly.

Object changes

  • Added the contractualRules field to the NewsArticle object. The contractualRules field contains a list of rules that you must follow (for example, article attribution). You must apply the attribution provided in contractualRules instead of using provider. The article includes contractualRules only when the Web Search API response contains a News answer.

Non-breaking Changes

Query parameters

  • Added Products as a possible value that you may set the category query parameter to. See Categories By Markets.

  • Added the SortBy query parameter, which returns trending topics sorted by date with the most recent first.

  • Added the Since query parameter, which returns trending topics that were discovered by Bing on or after the specified Unix epoch timestamp.

Object changes

  • Added the mentions field to the NewsArticle object. The mentions field contains a list of entities (persons or places) that were found in the article.

  • Added the video field to the NewsArticle object. The video field contains a video that's related to the news article. The video is either an <iframe> that you can embed or a motion thumbnail.

  • Added the sort field to the News object. The sort field shows the sort order of the articles. For example, the articles are sorted by relevance (default) or date.

  • Added the SortValue object, which defines a sort order. The isSelected field indicates whether the response used the sort order. If true, the response used the sort order. If isSelected is false, you can use the URL in the url field to request a different sort order.
