Google last week announced the sunset dates of the Doubleclick Bid Manager (DBM) API v1.1 Line Item service and the sunset of all deprecated DBM API services.
Deprecated DBM API services include the entirety of DBM API v1 and DBM API v1.1 Structured Data File (SDF) Download service. The sunset date is February 26, 2021.
According to Google, the sunset was originally scheduled for June 15, 2020, but it was postponed due to COVID-19.
For the Line Item and SDF Download services, Google recommends the use of the new Display & Video 360 API. The reporting service will still be Available in v1.1 after February 26, 2021.
Advertisers still using DBM API v1 Reporting service must migrate to v1.1.
