Matthew Etherington and Christian Dailly were the Hammers' heroes with the goals which knocked Town out 2-1 on aggregate.
Palace made sure of their place in the final 24 hours earlier with a dramatic penalty shoot-out victory over Sunderland.
Sunderland won the second leg 2-1 after losing 3-2 at Selhurst Park, but they lost 5-4 on penalties and will be back in Division One next season.
Since his Christmas arrival Iain Dowie has led Palace from fourth bottom to the post-season knockouts in a run that has included victories over all their play-off rivals.
