Mediation management
Stay organized with collections
Save and categorize content based on your preferences.
The AdMob API lets you manage your AdMob Mediation setup programmatically.
You can create and update mediation
groups
, add ad source
instances
, and
provide the ad unit
mappings
to enable calls
to multiple third-party networks
.
The following activities are available through the AdMob API and UI.
With the AdMob API you can:
- Create apps, link them to app stores, and add ad units.
- Create ad unit mappings for all of the waterfall ad sources you want included
in your setup.
- Create a mediation group with geo targeting and waterfall ad sources with
their associated ad unit mappings.
- Update a mediation group's ad sources, ad unit mappings, and eCPM values.
A mediation group can have many ad source instances, each having their own ad
unit mapping. For instance, mediation group A
could have the following lines:
- Ad source
B
with eCPM $10 and ad unit mapping b
- Ad source
C
with eCPM $8 and ad unit mapping c
- Ad source
D
with eCPM $6 and ad unit mapping d
The hierarchy of objects and maps is as follows:
