Override ad unit sizes in bid request

Type of issue

Question/Feature Request

Description

Is it possible to override adunit sizes for a specific bid request in that ad unit. Looking at the example below, my adunit accepts 2 sizes. I only want the first bid request to be able to bid on 300x250 sizes.

The primary use case for this is to allow for premium inventory sizes that I would only allow certain partners to bid on. Or if we have a partner with lower quality ads, we don't let them buy the larger inventory sizes

var adUnits = [
        {
            code: 'test-ad',
            sizes: [[300, 250], [300, 600]],
            bids: [
{
                    bidder: 'onedisplay',
                    sizes: [[300,250]],
                    params: {
                        dcn: '2c9d2b50015a5aa95b70a9b0b5b10012',
                        pos: 'header'
                    }
                },
                {
                    bidder: 'onedisplay'
                    params: {
                        placement: '3611253',
                        network: '9599.1',
                        bidFloor: '0.80',
                        keyValues: {
                            test: 'key'
                        }
                    }
                }
            ]
        }
    ];

@mmilleruva
I believe you can do this with labels http://prebid.org/dev-docs/publisher-api-reference.html#labels

You'd define a subset of sizes on the label and then label the bidder and it should get the subset of sizes in the request.

Actually not sure that's going to work @mkendall07. Labels aren't associated with sizes -- they're just tags that can be used to conditionally include/exclude bids. The sizeConfig feature supports overriding sizes, but that would be for all bids in the AdUnit.

I think that for a single bid in the AdUnit to have a subset of sizes, the bidder adapter would need to support that. Apparently not many do. So I think this is an enhancement request to allow per-bidder override of the sizes seen by each adapter.

@bretg almost all adapters are sending all possible sizes configured on adUnit to bid request.
If your bid supports only 300x250 you wont get any other sizes in response, you just have to setup placement in onedisplay member zone.
