RTB Bid TTL: warning when buyer expiry isn’t mapped
What’s new
If you set a minimum bid TTL (or min/max TTL on an RTB group) and the buyer response does not map an expiry or TTL field, Moja now shows a warning.
The warning is informational. You can still save a setup that uses default TTL only.
When expiresAt or ttlSeconds is mapped, the warning does not appear.
How to use it
Open Targets and create or edit an RTB target.
Go to Bid TTL Settings and set a minimum remaining TTL.
Check Response Mapping for a buyer expiry or TTL field.
If none is mapped, read the warning on Bid TTL Settings and on Response Mapping, then map the buyer field or keep default TTL on purpose.
On an RTB group, the same warning can appear at group level and on each target that has a TTL threshold without a mapped expiry.
Impact
You can tell whether Moja is using a buyer-provided bid expiry or falling back to default TTL, before you assume freshness is enforced from the buyer.
