Google Open Bidding

Introduction

InMobi is a certified bidder on Google Open Bidding (GOB), supporting integration via both Google Ad Manager (GAM) and AdMob across in-app, web, and CTV inventory. This server-side integration uses the OpenRTB protocol and does not require an SDK.

Requirements

To successfully integrate InMobi with Google Open Bidding, ensure you meet the following prerequisites:

  • Active account on GAM or AdMob for Mobile App and GAM 360, Google AdX, and GAM SMB (with CTA/Click to Accept feature only) for Web.
  • App-ads.txt / ads.txt setup (recommended).
  • Supported Ad Formats:
    • Mobile App: Banner, Video (any format), and Native
    • Web: Banner, Instream and Outstream Video, and Native
  • For SDK-based integrations, see Google AdMob and Google Ad Manager.

Configure Google Console

After setting up your InMobi account, you must enable InMobi on your Google dashboard and start sending us traffic. Use the toggles below to view platform-specific integration instructions.

Note

To complete the Google Open Bidding setup, you must view and sign the partnership agreement, fill out the onboarding form, and acknowledge the bidding agreement.

If you already have an InMobi account, you won’t need to fill out the onboarding form again. Instead, you will see a message indicating that an account already exists. This is based on the Google Publisher ID passed by Google, which InMobi uses to identify existing accounts.

Note

All payments and billing-related communication will be made to the intermediary - Google Open Bidding. Contact your intermediary for all billing/payment-related queries.

Integration Request Approval

Since Open Bidding does not require an SDK integration, InMobi must approve your request before going live. Once your setup is complete, share your Google Publisher ID with your InMobi Customer Success Manager or email googlebidding@inmobi.com.

Note

Contact InMobi for approval only after completing your setup. Approval activates ad requests, and incomplete setups will result in failed ad responses. If your status shows as Rejected, it can be reversed. This is not permanent and may be due to previous manual clean-ups of pending requests.
