   The https://github.com/killbill/killbill-litle-plugin[Litle&Co. plugin] on the other hand expects some fields like the `paypageRegistrationId` (using Litle's tokenization service):
   
  
positive.code:      "http://127.0.0.1:8080/1.0/kb/accounts/268983f2-5443-47e4-a967-b8962fc699c5/paymentMethods?isDefault=true"

  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):
  
negative.code: 
  The payment method will be marked as inactive in Kill Bill. The actual deletion of the information is plugin specific (delete the information in the gateway, etc.).
  
  Note that by default you cannot delete the default payment method on an account (because it is assumed to be used for recurring payments). If you really want to delete it though, you can pass the query parameter deleteDefaultPmWithAutoPayOff=true to the previous call. This will delete it and set the account in AUTO_PAY_OFF (invoices won't be paid automatically anymore).
