PAAPI support for nested component auction #1160

Open ghost opened 4 months ago

ghost commented 4 months ago

Can PAAPI support more than 2-levels of auction?

looks like PAAPI only supports upto 2-level auctions (a top-level auction plus a 2nd-level component auctions). In today's contextual bidding flow, there can be more than one SSP between the publisher and the DSP. Assuming the top-level auction is run by the publisher/their ad-tag/their-adServer/etc (ie not one of the SSPs), then it is impossible for each of the SSPs to participate in the same PAAPI auction as they would in the contextual auction.

Put it differently, I would like to run a 3-level auction in PAAPI:

level1: top-level auction by the publisher-adServer level2: component auction by the SSP (SSP1) which the publisher is directly connected to level3: component auctions by each of the SSPs (eg SSP2, SSP3) that get requests from SSP1

if I construct an auction config as outlined above and call runAdAuction, it fails with TypeError: Failed to execute 'runAdAuction' on 'Navigator': Auctions listed in componentAuctions may not have their own nested componentAuctions.

Has anyone run into this or considered multi-level auction in PAAPI flow?

No, we do not support more levels of auction.

@johnzhang-amzn, you might find the references in https://github.com/WICG/turtledove/pull/251 of interest. TURTLEDOVE started out with only a single-level auction, a local decision over the demand coming through a single SSP.

@dmdabbs I saw #251 . That was the doc that made to realize the limitation and our test to confirm.

Any plans to relax that to allow multiple-levels of auction?

Not for me to answer. I provided that link to indicate that what we have now was requested/negotiated some time ago and at this point in the process is probably what it's going to be.

If there was the option that there could be multi level component auctions, it would be interesting for Bidswitch to host one on behalf of SSP's and trading pairs that currently trade via BSW on Ortb
