Line Item 2.0 Bidding Object Bug Fix

What is it? A fix to an issue discovered regarding 2.0 line item endpoints when using a PATCH call to adjust bidding object keys. Previous behavior was that any change to bidding.pacing, bidding.custom, or bidding.bid_shading_control bidding object keys would reset bidding.pacing_behavior, bidding.multiplier, and bidding.catchup_behavior back to their default values. With this fix, bidding.pacing_behavior, bidding.multiplier, and bidding.catchup_behavior will only reset to default values when a change is made to bidding.strategy.

How am I affected? On March 31, 2025, a fix will be implemented that will no longer reset bidding.pacing_behavior, bidding.multiplier, and bidding.catchup_behavior when a PATCH call is made to update bidding.pacing, bidding.custom, or bidding.bid_shading_control. Any change to bidding.strategy will continue to reset bidding.pacing_behavior, bidding.multiplier, and bidding.catchup_behavior back to their default values. The affected endpoints are listed below:

• /line-items/bulk
• /line-items/bulk/validate
• /line-items/{id}

Update to Advertiser 2.0 PATCH Required Fields

What is it? A fix has been made to an identified bug that was allowing for the use of the advertiser PATCH method to update active advertisers without specifying the advertiser category or advertiser domain. Due to exchange requirements, those fields are required to be declared on the advertiser level to ensure that information is always being passed.

How am I affected? On March 31, 2025, a fix will be implemented that will prevent using the PATCH method to update active advertisers if they don't have a declared advertiser category or advertiser domain. The affected endpoints are listed below:

• /advertisers/{id}
• /advertisers/bulk
• /advertisers/bulk/validate

Ads.txt Targeting Key Update

What is it? On March 11th, 2025, Beeswax will add support for app-ads.txt into the existing ads.txt targeting key.
