1. Overview

1.1 Summary

• This guide covers details of the Server-to-Server RTB integration protocol system that operates between Partner (Demand-Side, Bidder) and Dable (Supply-Side).
• The guide defines the Open RTB-based Object models (including Bid Request and Bid Response) and Attributes supported by Dable RTB.

1.2 Base Open RTB Specification

• Open RTB API Specification Version 2.5
• Open RTB Dynamic Native Ads API Specification Version 1.2

1.3 Basic Auction on the Dable Exchange

1. Dable sends Bid Requests to Partners (hereinafter referred to as Bidders).
2. Bidders place a bid through Bid Response. a. Returns “No-Bid” response in case not bidding on the request b. Considered as No-Bid If no response is received within a time period, which is agreed upon in advance and stated separately
3. Dable determines a winning bid (winner and its price) in real-time.
4. The winner’s ad is served to the user.
5. The user’s browser calls the Open RTB Native’s Event Tracker.

1.4 RTB Server-To-Server Protocol

• The request/response protocol uses HTTP POST Method and JSON Body.
• HTTP Request Headers
  • [Required] Open RTB Version (ex: x-openrtb-version: 2.5)
  • Data Format (ex: Content-Type: application/json)
• HTTP Response
  • HTTP Response (Status Code)
    • Bid: 200 (with JSON body)
    • No Bid: 204 (Leave empty or enter reason in JSON body with 200 OK)
    • Error: 400

2. Important Integration Notes

2.1 Note regarding impression tracking

seatbid.bid.adm.native.eventtrackers - This attribute enables the Bidders (DSPs) and third-parties to continuously track ad impressions.

2.2 Multiple bid responses and multiple seat bids

Bidders (DSPs) may send multiple bids in a seatbid. These are collected in the bid array in the seatbid object. Dable reviews all bids from all seats, excluding the ones that are in the blocklist or invalid. The highest bid among the valid bids wins the auction.

2.3 OpenRTB Native Specification

Dable RTB supports Native Ads 1.2 for OpenRTB. Please refer to the following important notes.

• native.request is a string
• Bidders must use a serialized string in the adm field (as noted by OpenRTB) to return ad markup

3. Dable BidRequest Specification

4. Dable BidResponse Specification

RTB responses contain bids that reference specific impressions within a bid request. Bids are in essence an offer to buy. The bid response consists of the top-level bid response object and optional objects that depict the specific bids. An empty HTTP response constitutes a no-bid and is in fact the most bandwidth friendly form of this signal although returning a response with a “no-bid reason” is encouraged. A malformed response or a response that contains no actual bids will also be interpreted as no-bid.

lurl	string		Loss notice URL called by the exchange when a bid is known to have been lost. Substitution macros may be included. Exchange-specific policy may preclude support for loss notices or the disclosure of winning clearing prices resulting in ${AUCTION_PRICE} macros being removed (i.e., replaced with a zero-length string).

7. Contents Checking Process

7.1 Contents Post-checking

• All contents that won in Dable RTB may be subject to post-checking process.
• Landing URL that won Dable RTB may be called once, or once in every hour at the maximum. Number of calls may increase if Dable chooses to check manually.
• Basically, Landing URL is the URL of Link Response Object included in adm.
• When a URL is called during post-checking process, ${AUCTION_PRICE} macro in the URL will be replaced to 0 and a parameter (&dable_check=1) will be added to the URL. (*We recommend adding a logic that prevents the Landing URL with the&dable_check=1 parameter from being included in actual performance measuring and cost.)
• If a content has been found with issues during the post-checking process, the content may not be able to participate in future biddings.
• If calling a URL fails (User Agent returns 403 response), post-checking process may be considered as a fail.
