Microsoft Advertising has extended the UET Conversions API event submission period from 7 days to 90 days. This change allows advertisers to send server-side conversion data for events occurring up to 90 days ago, accommodating long sales cycles and delayed conversions.
According to the updated Microsoft Advertising help page, the submission limit of 90 days is distinct from the conversion goal’s attribution window, within which events must fall to be attributed.
