Germany paid reparations as part of the hated Versailles Treaty following WW1 - and they were quite burdensome, as well as despised. But note a distinction: Germany signed a peace treaty to end WW1 (and to stave off complete defeat).
But in WW2, the allies were determined to completely defeat Germany, occupy her and find ways to keep her from being aggressive again - so in WW2, Germany was completely defeated and occupied. So after WW2, Germany didn't pay "reparations" exactly - there was no similar treaty to Versailles, with specific payment requirements. But that doesn't mean that Germany didn't pay in other ways.
