For debugging and logging purposes, successfully loaded ads provide a
ResponseInfo object. This object contains information about the ad it loaded.
Each ad format class has a property responseInfo which is populated after
it loads.
Properties on the ResponseInfo include:
Property
Description
adapterResponses
The list of AdapterResponseInfo containing metadata for
each adapter included in the ad response. Can be used to debug the
waterfall mediation and bidding execution. The order of the list matches
the order of the mediation waterfall for this ad request.
Returns the AdapterResponseInfo corresponding to the adapter
that loaded the ad.
mediationAdapterClassName
Returns the mediation adapter class name of the ad network that loaded
the ad.
responseId
The response identifier is a unique identifier for the ad response. This
identifier can be used to identify and block the ad in the Ads Review Center (ARC).
responseExtras
Returns extra information about the ad response. Extras may return the
following keys:
creative_id: The creative ID of the selected ad. Returned
for reservation ads only.
line_item_id: The line item ID of the selected ad.
Returned for reservation ads only.
Adapter Response Info
AdapterResponseInfo contains metadata for each adapter included in the ad
response which can be used to debug the waterfall mediation and bidding
execution. The order of the list matches the order of the mediation waterfall
for the ad request.
For each ad network, AdapterResponseInfo provides the following
properties:
Property
Description
adapterClassName
A class name that identifies the ad network.
credentials
A string description of adapter credentials specified in the
Ad Manager UI.
adError
Error associated with the request to the network. Null if the network
successfully loaded an ad or if the network was not attempted.
latencyMillis
Amount of time the ad network spent loading an ad. 0 if the
network was not attempted.
description
A log friendly string version of the AdapterResponseInfo.
