Hi Romain,
Thank you for reaching out to us.
As per this article (https://support.google.com/admob/answer/13420272?hl=en&sjid=18313676657718273234-AP), under the "Set up your ad sources " after you create your ad unit id, you can set up bidding sources (https://support.google.com/admob/answer/13407143) and waterfall sources (https://support.google.com/admob/answer/13404328). Just remember that the type of source you set up determines how they bid for your impressions. Bidding sources place bids in real-time and compete in a single auction, while waterfall sources are called individually in the order of their eCPM, which is set by you.
