At Vistar, we support currency conversion that allows third-party DSPs to bid on non-US inventory available in Vistar’s Supply Side Platform (SSP). Vistar works with media owners that have inventory available in a number of countries. While some third-party DSPs may only support bidding in United States dollar (USD), Vistar can seamlessly convert bid responses in USD to the currency of the media owner (and vice versa).
Vistar uses the Open Exchange (OXR) to retrieve the daily exchange rates and use for currency conversion.
Bid request and response process
