I have a Macbook Air 2017 with 512GB SSD and I want to put the drive in a 2018 MacBook Pro that came with only 128GB.

What do I need to do this?

You can’t do this.

The 2018 MacBook Pro storage is soldered to the logic board and is very different from the proprietary M.2 interface of the 2013-2017 MacBook Air computers. This applies to both the 15-inch and 13-inch models.

You either have to get an MacBook Pro with greater internal storage or you can remove the SSD from the 2017 and put it into an external enclosure; that’s if the 2017 MBA is otherwise useless. If it still has life, then get an external drive for additional storage.
