Invite a child publisher

Publishers can request access to another publisher's inventory. The publisher requesting access is known as a "parent publisher." The publisher who shares their inventory is a "child publisher."

Parent publishers can send invites to one or more child publishers. 

Note that the MCM child network approval process usually takes a few days, but in some cases it can take 2-4 weeks.

For details on the status of child publishers during the onboarding process, go to Check child publisher readiness.

Invite multiple child publishers

You can invite up to 1000 child publishers at once. To get started, we suggest inviting a smaller number and gradually increasing it until you’re familiar with the process. 

To invite multiple child publishers, you use a CSV file. You can upload a single file for Manage Inventory and Manage Account children. For Manage Inventory entries, don’t include revenue share data or you’ll get an upload error.

1. Click Admin, then MCM, then Child publishers.
2. Click Upload child publishers.
3. (Optional) To review the required format, click Download sample CSV file.
4. Choose an upload option:
   • Click Browse and select your CSV file.
   • Drop your CSV file into the box.
5. After your file uploads, click Confirm.

If any error messages appear after your upload, correct the file and upload it again.   

Follow up on an invitation

Until the child accepts the parent’s invite, the parent can’t view any detailed status information for the child. 

An invitation is valid for 90 days. If the child doesn’t accept the invitation within 90 days, you can resend the invitation. If you need to change the proposal, withdraw the invitation so the child’s status becomes inactive, and send a new invitation.
