Timestamp validation

What you need to know and do

What you need to know and do
Change summary	Effective October 30, 2026, data submitted to the `/data/advertiser` and `/data/thirdparty` endpoints with an invalid `TimestampUtc` value will be rejected and returned as a failed line under a new error code, `InvalidTimestampUtc`. Data is considered invalid when it is either: A timestamp whose expiration (`TimestampUtc` + `TTLInMinutes`) is more than 1 hour in the past. A timestamp more than 1 hour in the future.
Action required	To avoid dropped records, make sure the timestamp in UTC on submitted data reflects a current, non-expired value before October 30, 2026. For details, see Timestamp in UTC

Data Usage and Spend API integration

What you need to know and do
Change summary	Scheduled data usage reports will soon be replaced by the Data Usage and Spend API. Use it to access third-party data usage and insights on demand, including gross revenue, impression counts, and data costs. The API returns data on demand, so you no longer have to wait for emailed reports. NOTE: Finance reporting remains unchanged and remains the source of truth for billing.
Action required	None, but if you have a Data Supplier Agreement (DSA), we recommend switching to the API. For details, see Third-party data usage and spend.
