We are thrilled to let you know that Bing Ads API Version 13 is now generally available in production to all our customers worldwide!
With the availability of Bing Ads API version 13, version 12 is deprecated and will sunset by October 31, 2019. We will sunset i.e., shut down all the v12 service endpoints (Ad Insight, Bulk, Campaign Management, Customer Billing, Customer Management and Reporting services) on October 31st. Please migrate to the v13 services as soon as possible to avoid any disruption to your tools once the v12 services are sunset.
As with any version upgrade you’ll want to read the migration guide for details about new features and potential breaking changes.
