  • To create accounts for Google OB, use the link above-mentioned instead of, as this link only helps you monetize with InMobi via different integrations besides Google OB.
  • If you have an existing account with us, you must still create a new one with a new account name and email ID. If you try using your existing account name and email ID, the system will throw an error.

Verify Your InMobi Account

Follow the instructions below to verify your InMobi Account:

  1. Check your registered email inbox or spam folder for a verification email from InMobi.
  2. Click Get Started. Your browser directs you to set your password.
  3. Enter your new password and click Set password. Your browser redirects you to the InMobi Publisher Dashboard Sign Up page.
  4. Click Log In.
  5. Enter your email address and click Next.
  6. Enter your password and click Log In. Your browser directs you to the dashboard homepage.


  • Resend Invite: If you haven’t received the verification email, click the Resend button on the InMobi Publisher Dashboard Sign Up page and resend the invite.
  • Forgot Password: If you have forgotten your password, follow the instructions to create a new one.

Step 2: Update Billing Information

To update your company details and payment information, follow the instructions below:

  1. From the left navigation panel, select Finance > Payment Settings > Payment Information.
  2. Click Edit Payment Information and enter the required details.
  3. Click Save.

You have successfully updated your company and billing information.


All payments and billing-related communication will be made to Google directly by InMobi. We require you to fill in this information on the InMobi account for customer identification and correspondence only. You can contact the Google team for all billing/payment-related queries. For more information on billed impression and revenue tracking, see your Google account.

Step 3: Add Inventory and Placements

To register your published app, website, or unpublished app with InMobi on Google OB, see Add Your App or Website.

If your apps have been added and you would like to create new placements specifically for bidding on Google, follow the instructions below:

  1. Search for the app or website on which you want to create a placement and click + Add a placement.
  2. Select an ad unit. For more information on our ad units, see Ad Units.
  3. Ensure the Audience Bidding toggle is on, and the Google Open Bidding option is the default partner selected in the dropdown.


  • Create only one placement per ad format.
  • If you can’t find the Google Open Bidding option in the dropdown, your account cannot be used for Google OB. Follow Step 1 to create an account specific to Google OB. For more information, contact your Customer Success Manager or write to

Step 4: Upload InMobi’s App-ads.txt Entries

Adding InMobi as an authorized seller to your app-ads.txt file is highly encouraged to protect your inventory and let your buyer know which sellers can sell your in-app inventory. Not completing this step will limit the number of DSPs able to buy your inventory.

Follow the instructions below to copy or download the list of entries from the InMobi Publisher Dashboard:

  1. From the left navigation panel, select My Account > Manage App-ads.txt.
  2. From the Manage App-ads.txt sub-tab, copy or download the curated list of direct and reseller entries.
  3. Add the entries to your app-ads.txt file.


  • You will be unable to add our curated list of sellers to your app-ads.txt file if you haven’t updated your billing information. Refer to Step 2 to complete this.
  • If you monetize any mobile-web inventory, contact to receive InMobi’s ads.txt entries.

Step 5: Add InMobi as a Yield Partner and Create Yield Groups on Google

After setting up your InMobi account, you must enable InMobi on your Google dashboard and start sending us traffic. Follow the instructions below:

  1. Add InMobi as yield partner/bidder for Open Bidding.
  2. Set up yield groups at an ad format (banner/video) and inventory type (web/in-app) level, and then add InMobi as a yield partner to this group.

If you use Google Ad Manager for Google OB, see the following topics:

If you use AdMob for Google OB, see Add a bidding ad source.


If you are using Google Ad Manager (GAM) SMB or AdMob, you will be prompted to fill out this form as a part of the Onboard Online /Sign Partnership Agreement on your Google Dashboard. InMobi’s terms for Google Open Bidding are listed at the bottom of this form. If you use GAM 360 (premium), you will NOT be shown this prompt on the Google Dashboard. Hence, we recommend filling out the form for faster onboarding.

After completing all five steps, request your Customer Success Manager or write to to approve your OB request by sharing the following: InMobi Account Name, InMobi Account ID, Google Publisher ID, and your Country of Registration. Once your request is approved, the integration is complete, and we will start receiving traffic from you.

Additional Instructions for GDPR

Follow the additional instructions below about GDPR settings on your Google dashboard for higher monetization results. The following configuration applies to traffic from European Economic Area and publishers using AdMob/GAM CMP for GDPR consent purposes. Google CMP provides two ways of adding ad partners on their AdMob/GAM platform:

  • Commonly used ad partners
  • Custom ad partners

InMobi is not part of ‘Commonly used ad partners’ by default, and you must add it manually by selecting Custom ad partners.

Follow the instructions below to enable InMobi under Custom ad partners on your Google dashboard.

  1. On the Google Dashboard, select Privacy & messaging GDPR Settings Review your ad partners.
  2. Select Custom ad partners and then InMobi from the list and save the setting.
