Remove The Legacy /auction Endpoint

[SyntaxNode]

Type Of Issue

Feature Removal

Description

PBS-Go still implements the original /auction endpoint, utilizing a custom data model instead of OpenRTB. This endpoint has long been deprecated and removed from public facing documentation. It is difficult to maintain and is barely used. Hosts report less than 0.1% of all requests are using the endpoint. It's time has come.

Proposal

Remove the original /auction endpoint in a phased approached as follows:

• 0.179.0: Include a config to enable the /auction endpoint, defaulting to true. Hosts should experiment with setting this option to false in staging/testing environments to ensure there are no surprises when it's removed.
• 0.180.0: Change the default to false. Hosts may set the flag to true if they encounter an unexpected problem.
• 0.181.0: Remove the endpoint entirely and all related code, including all adapter Call methods.

[SyntaxNode]

Discussed in the Preber Server Commitee. There is no opposition to this plan.

[SyntaxNode]

PBS-Go 0.179.0 was released as planned with a new config option enable_legacy_auction to disable the legacy /auction endpoint. It defaults to true, but will default to false in the upcoming 0.180.0 release.

[SyntaxNode]

PBS-Go 0.180.0 was released as planned where enable_legacy_auction now defaults to false. All code supporting the legacy endpoint will be removed in 0.181.0.

[SyntaxNode]

Removal of the /auction endpoint code has been delayed to 0.182.0 to give bidders a bit more time to review their adapters.

[SyntaxNode]

The legacy /auction is fully removed in 0.182.0.
