Welcome to OpenRTB for publishers. Real-time bidding (RTB), also known as OpenRTB, enables programmatic bidding on individual ad impressions in real-time auctions. Buyers programmatically purchase inventory on an open exchange that lets many buyers bid in auctions on inventory from multiple publishers. OpenRTB is a highly effective way to reach large audiences through open exchange programmatic buys. This section contains everything publishers need to integrate PubMatic's oRTB implementation into their workflow.
