prebid-mobile-android Question: Default battr values in ad request payloads

Hi Prebid team,

We checked our implementation and we don’t explicitly set any battr values in the SDK. However, in every partner request body payload, the response from our request contains:

"battr": [1,3,5,8,9,10,11,14,17]

We understand it’s possible to override these values, but we’d like to confirm:

Is including this default battr intentional behavior on the Prebid Server side?

Thanks for your guidance!

Hi @ChrisHuie, following up on the above question, can you confirm if this is intended behavior?

Hi @andriiginting !

Prebid Server doesn’t modify the battr field—that’s part of the publisher’s business logic—so this isn’t intended behavior.

From your description, it looks like these attributes are being added via the stored request. You should contact your hosting provider to find out why the server is adding battr attributes.

Hi @YuriyVelichkoPI, I see. So, is there a possibility that the battr value we send through the SDK will be different from the one defined by the publisher?

Hi @andriiginting ! I'm sorry, but can you describe in detail what is happening? I can't see the full picture now of which party and when sets or changes the battr.
