How do you create a "coinbase tx"? Can it be built via createrawtransaction or can it only be created in code? Then I don't fully understand how to build this transaction.

Create it manually: createrawtransaction doesn't allow you to set the script of the input.

Code:

version: 02000000
marker: 00
flag: 01
txIns:
num: 01
in-1:
txid: 0000000000000000000000000000000000000000000000000000000000000000
index: ffffffff
