  You can add as many payment methods as needed to a given account (across one or multiple plugins). You can specify for each payment call the payment method to use, or leave it blank to use the default.
  
  Each payment method in Kill Bill has a unique uuid associated to it. Use this uuid to change the default payment method on the account (in this example, the payment method id `a91161b0-d159-11e3-9c1a-0800200c9a66` becomes the default one):
