MoPub OpenRTB 2.5 and Native 1.2 Integration Guide

Important: Please review the changelog periodically for updates!

1. Overview

Summary

This doc serves as an integration guide and FAQ for our OpenRTB 2.5 + Native Ads 1.2 specs. Please consult the document on the demand support center and the changelog at the bottom of this guide for the latest updates.

If there is a conflict between this integration guide and your existing agreements with MoPub and Twitter, your agreements supersede this guide document.

Basic Auction on the MoPub Exchange

  1. MoPub receives an ad request from a mobile device.
  2. MoPub makes an HTTP POST request to all partner bidder HTTP endpoints. Each bidder must respond within the number of miliseconds passed in the bidrequest.tmax field.
  3. MoPub runs a second-price auction based on all the valid responses from the bidders.
  4. MoPub pings the winning bidders nurl(s) to notify the DSP of a win.
  5. MoPub sends down the winning bid’s HTML and imptrackers or burl to the client.
  6. The mobile device pings the imptrackers or burl URL(s) after the ad markup is rendered.

See section 2.4 for more information on nurls and impression tracking.

IMPORTANT: All fields are populated in the bid request if available. We never pass null values or empty strings. If a parameter is noted as not always being passed, that parameter may not always be present in the bid request. For example, if the request doesn’t contain an SDK version, we omit it from the request.

It’s possible that an attribute is marked “not always passed” when there is a very low probability of this happening; for example, country is passed 99% of the time.

2. Important Integration Notes

2.2 burl, nurl, and Impression Tracking Updates

MoPub is making some important changes in the RTB 2.5 implementation to more closely align to the OpenRTB standard and introduce new ways for bidders to consistently track impressions for themselves and 3rd parties. Starting with this release, the following is available:

  1. bidresponse.seatbid.bid.burl - this standard OpenRTB field is one of two options that allows a bidder to submit a single impression tracker that will be sent on the impression / charge event for the ad.

  2. bidresponse.seatbid.bid.ext.imptrackers[] - this existing extension field is one of two options that allows a bidder to submit 1 or more impression trackers that will be sent on the impression / charge event for the ad.

Leveraging either field above will ensure bidders (and 3rd parties) minimize discrepancies with MoPub’s invoices. * The logic for sending trackers in these two fields is identical. * This does not apply for native. Bidders are required to use the native.imptrackers array to submit impression trackers instead.

  1. bidresponse.seatbid.bid.nurl - this is an optional variable to notify a bidder when they won the auction. This does not guarantee that an impression is served, nor does MoPub charge when this tracker is sent
    • The nurl is fired server-side.
  2. bidresponse.seatbid.bid.ext.nurls[] - this optional extension field allows a bidder to submit multiple nurl trackers to optionally notify third parties of the win.
    • Note that if both the nurl and the array are provided, we only use what is present in the array field.

2.3 Multiple Bid Responses and Multiple Seat Bids

DSPs are encouraged to send multiple bids for each seat represented in the bid response. These are collected in the bid array in the seatbid object. We consider all bids from all seats, exclude the ones that do not match blocklist or are invalid, and take the highest of the remaining eligible bids across each seat.

bidresponse.seatbid.seat technical requirements:

  • Alphanumeric (azAZ09)
  • Max length of 40 characters
  • Ideally min 8 characters

Note: We currently support only 1 impression per auction, so these bids would all be competing for that single impression.

2.4 OpenRTB Native Specification v1.2

This update includes support for the Native Ads 1.2 sub-specification for OpenRTB. We have a few important notes regarding this update for MoPub’s exchange:

  1. Bidders have two options for returning ad markup:
    1. (preferred method) As a JSON object in the bid.adm_native field
    2. as a serialized string in the bid.adm field (as noted by OpenRTB)
  2. MoPub is adding support for the ‘Sponsored By’ data asset type, the eventtrackers, clicktrackers, and plcmttype fields.
  3. MoPub is requiring a minimum width and height of 80x80px for the icon asset. A value of 80 is passed in the bid request assets.img.wmin and assets.img.hmin.
  4. Main image and icon image height and width are required in the bid response image object.
  5. Current bidders in MoPub’s native ads can map the data fields to the following asset object ids:
    • 1 = title
    • 2 = main image
    • 3 = icon
    • 4 = text
    • 5 = ctatext
    • 6 = starrating
    • 7 = VAST
    • 8 = sponsored by

3. Bid Request Variables and Definitions

Please ensure you have the OpenRTB 2.5 Specification Guide available while consulting below. This document contains information and nuances specific to MoPub’s implementation and its expected that you also follow the guidelines presented in OpenRTB when unchanged.

Notes:

  • The following section naming follows OpenRTB for simplicity.
  • All fields are populated in the request if available. We will never pass null values or empty strings. If a parameter is noted as “always passed”, that parameter will always be present; otherwise, it may not be present in all requests. For example, if the request doesn’t contain an SDK version, we will omit that field from the request.
  • Types and descriptions from OpenRTB are not included below.
  • Any objects and attributes from OpenRTB not supported by MoPub are noted by strikethrough font.

${AUCTION_CURRENCY} The currency used in the bid (explicit or implied); for confirmation only.
${AUCTION_PRICE:B64} Settlement price using the same currency and units as the bid, encoded with Base 64 encoding. Example: MC4x and MC40MQ are the base 64 encodings of "0.1" and "0.41" respectively
${AUCTION_MBR} Market bid ratio = clearance price/bid price. If auction has no winner we will send “undefined”. Only supported in seatbid.bid.lurl.
${AUCTION_LOSS} Loss reason codes. Refer to list List 5.20. Only supported in seatbid.bid.lurl.
${AUCTION_MINIMUM_BID_TO_WIN} The minimum bid that the bidder would have needed to win the auction. Supported in both seatbid.bid.lurl and seatbid.bid.nurl.

4.4 Sending nbr When Not Bidding

Preferred for bidder to send a bare minimum bid response object when not bidding but providing nbr. For example:

{
  "id": "123",
  "nbr": 5
}

In this case the bidder would send back an HTTP 200 response code 200 with this barebones response object.
