Supply Side Partners issue HTTP POST messages containing OpenRTB bid requests. These requests are automatically forwarded to Demand Side Partners, and the The Agency marketplace collects bids based on demand. The bids, containing the creative and tracking pixel, are collected into OpenRTB bid response messages and are sent as the HTTP response body to the original HTTP POST. The ad and tracking pixel, located within the bid response object, are ready for immediate display.
Supply Side Partners will configure their servers to issue bid requests during retrieval of web content. The ad markup will be provided in the bid response. Returning the ad markup inside the web content will acknowledge the bid response as the selected winner via the resource request for the tracking pixel. The following example illustrates a request and response for a simple banner ad:

required Array of bid objects; each bid object relates to an imp object in the bid request. Note that, if supported by an exchange, one imp object can have many bid objects. |
|
seat: |
string |
optional ID of the bidder seat on whose behalf this bid is made. |
|

optional "1" means impressions must be won/lost as a group. Default is "0". |
|

object |
optional This object is a placeholder that may contain custom JSON agreed to by the parties in an OpenRTB transaction to support flexibility beyond the standard defined in this specification. |
Individual bid objects must contain the HTML ad markup that is to be displayed if the bid wins the auction in the "adm" field. Any impression tracking pixels for the purposes of bookkeeping and reporting should be included in this markup. The ad markup may contain OpenRTB substitution macros which will be replaced by the The Agency marketplace with the corresponding value (See Substitution Macros).
|

string |
required ID for the bid object chosen by the bidder for tracking and debugging purposes. Useful when multiple bids are submitted for a single impression for a given seat. |
|
impid: |
string |
required ID of the impression object to which this bid applies. |
|
price: |
float |
required Bid price in CPM. Note: Although this value is a float, OpenRTB strongly suggests using integer math for accounting to avoid rounding errors. |
|
adid: |
string |
optional ID that references the ad to be served if the bid wins. |
