Implementation notes

• Create use case (e.g. CapturePayPalPaymentUseCase or CapturePayPalOrderUseCase) in the payment bounded context. It should:
  • Receive an OrderID (string) as parameter
  • load the Order with the OrderId
  • call the CaptureOrder method of the API. This will return the transaction ID
  • add the transaction id to the order
  • store the order
  • If everything went well, return a success result object with the payment id and transaction id
  • If the API call failed, or something was not found in the database, return an error result object
• Test cases may be:
  • order not found
  • API call failed
