Outbound RTB XML Transient Tag Fix
Released: July 9, 2026
Multi-step XML RTB requests now populate transient and custom tag values consistently across request steps.
What changed
XML-formatted multi-step outbound RTB requests can now pass values extracted from an earlier XML response into a later request.
XML attribute-style keys and other non-standard response keys are handled correctly in request mappings.
This improves reliability for multi-step XML RTB integrations that reuse values across steps.
