Got it.
How about mapped as string instead of object and put encoded json string like below ?
"bidder_response-body": "{\"bid_response\":{\"responses\":[{\"member_id\":104,\"exclusive\":false,\"no_bid\":true,\"no_price_reduction\":false,\"price\":0.0,\"bidder_revshare\":0.0,\"bidder_minimum_cpm\":0.0,\"creative_id\":0,\"custom_macros\":[],\"buyer_currency\":\"USD\",\"auction_id_64\":7475650378184842386,\"pixel_type\":\"null\"}]}}"
I put the data successfully, can I search it using value in the json data ? ( e.g : no_bid : true ) )
Thanks
