Getting Started

Flipkart Commerce Cloud’s Ad monetisation service (FCC AdMon Service) enables you to monetise your properties such as website, MSite, and Apps (Android and iOS) by selling ad spaces. Presently, the supported advertising content includes ‘Display ads’ on your properties (websites, mobile apps) across geographies and across publishers.

Who can integrate with Ad-Tech Services?

  1. You’re a Flipkart Commerce Cloud Customer
  2. You have subscription or trial access to FCC Ad Monetization product
  3. You own one or more consumer properties – website, mobile app (Android/iOS), mSite

How can I integrate with FCC AdMon Service?

OpenRTB is the main integration process for working with the FCC AdMon Service.

Details required to be onboarded on FCC AdMon Service

Network Details

Each network, an aggregation of demand from advertisers and supply from publishers, has to be onboarded on the FCC AdMon Service. The details required for network onboarding have to be shared offline.

Inventory Details

The monetizable ad inventory available on the web/app has to be onboarded as supply constructs on the FCC AdMon Service. The ad inventory needs to be defined according to the guidelines mentioned in this document.

Creative format Specifications

Specifications for the creative formats that need to be supported and integrated into the FCC AdMon service have to be shared offline. These include:

  • Channels supported for given Creative Format (Desktop, Msite, IOS, Android, Tablet)
  • Image Dimensions supported for given Creative Format ( Height and Width of the image)

Advertiser Account Details

For an advertiser who wants to advertise on the Publisher, there will be an advertiser account, the details can be shared offline and the account admin will onboard the account. The details required for the advertiser account onboarding can be found in this document itself.

Key-Value Pair User Segments for Targeting (Optional)

Key-value pair targeting will be provided as a feature to the publishers to define custom targeting criteria such as demographics, behaviour etc. When an Ad request will come from a publisher that has key-values in the request, demand that targets those key-values will be eligible to serve for that Ad request.

Defining Key-Value pairs

Pre-defined list of key-values has to be shared by the publisher for segment definition and to be used for targeting in demand creation in ad serving. All the possible values for a particular key will have to be shared by the publisher. For example:

  • Age
    • 18-32
    • 33-60
  • Gender
    • Male
    • Female
    • Unknown

The publisher will pass the same “key-value” pair in the ad request against which the applicable campaigns based on the targeting criteria will be selected.

CDN Details

Each network, an aggregation of demand from advertisers and supply from publishers, will provide access to their CDN to upload the creatives so that Ads can be served efficiently.

Fallback Banner

Each publisher needs to have a fallback mechanism where if an Ad banner is not served due to any reason, then a default banner can be shown for that slot. The dimensions of the fallback banner should be defined as per the dimensions of the slot.

Getting Started with OpenRTB

FCC Ad Monetisation service supports the integration specifications for OpenRTB 2.5. We have also provided example requests and responses to make it easier for you to understand the integration process.

Introduction to OpenRTB

OpenRTB project provides open industry standards for communication between buyers of advertising and sellers of publisher inventory. The overall goal of OpenRTB is and has been to create a lingua franca for communicating between buyers and sellers.

The following figure illustrates the OpenRTB interactions between an exchange and its bidders. Ad requests originate at publisher sites or applications. For each inbound ad request, bid requests are broadcast to bidders, responses are evaluated under prevailing auction rules, and a winner is selected. The winning bidder is notified of the auction win via a win notice. Ad markup can either be included in the bid prospectively or in response to the win notice.

A separate billing notice is also available to accommodate varying policies enacted by exchanges that are beyond the scope of the OpenRTB specification (e.g., billing on device delivery, viewability, etc.). The win notice informs the bidder’s pricing algorithms of a success, whereas the billing notice indicates that spend should actually be applied. A loss notification is also available to inform the bidder of the reason their bid did not win.

The URLs for win, billing, and loss notices and the ad markup itself can contain any of several standard macros that enable the exchange to communicate critical data to the bidder (e.g., clearing price).

For the purpose of integration with the FCC AdMon Service, only Bid Request and Bid Response are relevant.

Supported Ad Formats

FCC AdMon Service supports Native display ads format.

API Integration Guidelines

Introduction

The FCC AdMon Server to Server API spec allows publishers to integrate with FCC AdMon Service directly from their server. This document lays out the Ad request, response structures and the parameters included in each of them to enable publishers to integrate with FCC AdMon Service .

API Endpoint

Publishers can use the following endpoints to integrate with the FCC AdMon Service:

v1/dsp/getBids?client=publisherId

HEADER PARAM:

X-AUTH-TOKEN: This is the unique Authentication Key generated on FCC’s end and shared with the client. Inorder to get the response successfully, passing this header in the request will be crucial

X-PERF-TEST: true, for non-production & performance testing flows and false, for production flows

Publisher ID will be shared after the network is onboarded

Recording events on the Ads

The FCC AdMon service tracks the ad interaction events only when the trackers are fired. The events that are tracked are:

  1. Impression: This event has to be fired when the ad is loaded on the client (app/site)
  2. View: This event has to be fired when the ad is in the viewable port for the user. Viewability can be defined by the publisher. (Recommended: IAB guidelines – ad which appears at least 50% on screen for more than one second.)
  3. Click: This event has to be fired when the user clicks on the advertisement.

To record impression/ view /click on the ad, follow these steps:

  1. Get the list of URLs for that event for the ad from the ad markup.
  2. For each tracker url, do the following:
    1. Send a GET request to the urls, with an http client.
    2. Retry up to 5 times if the url fails, with an exponential backoff defined by retryTime * Uniform[0, 1], and retryTime doubled for every failure with start retry time as 1 second.

The tracker events have to be fired in real time so that the budget and frequency capping systems can work.

Impression Tracker

This event is to be fired when the tenant ( website / Mobile App SDK receives the Ad Bid response). This event helps in calculating the efficiency of serving Ads.

Type: GET

Sample: https://host:port/adImpression?pl=encryptedPayload

Query Params

Description

pl

This will contain the encrypted data generated while serving.

View Tracker

This event is to be fired when the Ads become visible on the viewport of the user. This event helps in calculating the performance of serving Ads.

Type: GET

Sample: https://host:port/adView?pl=encryptedPayload&vst=[STARTTIME]&vet=[ENDTIME]

Query Params

Description

pl

This will contain the encrypted data generated while serving.

vst

This is the start time of the view event i.e the instance when the banner comes into the view port for the first time.

vet

This is the end time of the view event i.e the instance when the banner comes out of the view port.

Click Tracker

This event is to be fired when the Ads are clicked by the user. This event helps in calculating the performance of serving Ads.

Type: GET

Sample: https://host:port/adClick?pl=encryptedPayload&et=[EVENTTIME]

Query Params

Description

pl

This will contain the encrypted data generated while serving.

et

This is the event time i.e when the click event is triggered.
