Bid Request Lifecycle

The following page describes the lifecycle of a bid request as it flows through the various components of the system.

1. The exchange sends a bid request to the router where it is parsed by the exchange connector
2. The router relays the bid request to the Augmenter
3. The augmenter returns augmentations("+") to the router
4. The router sends augmented bid request("BR+") to the bidding agent
5. The bidding agent computes a bid and returns it to the router
6. The router relays the bid back to the exchange
7. The exchange (or Ad Server) sends a win notification to the Ad Server Connector

• The Ad Server Connector forwards the win to the post-auction service

1. The post-auction service forwards the win notification to the agents

Additionally bid requests, wins as well as other events such as clicks are also forwarded to the logger for persistence.
