Introduction

Real-time bidding (RTB), also referred to as OpenRTB, is the programmatic means of enabling bidding of individual ad impressions through real-time auctions. Inventory is purchased on an open exchange, allowing many buyers to bid on inventory from multiple publishers in an auction. This can be a highly effective way to get access to large audiences through open exchange programmatic buys.

 

PubMatic supports Ad Serving integration using OpenRTB 2.3, as well as a proprietary API. This documentation covers the OpenRTB Ad Serving integration. The latest OpenRTB 2.3 specifications are available at  http://www.iab.com/rtbproject .
