Remove inventory with a Transaction message
To remove specific property or itineraries from inventory, use a Transaction
message in the root element <Transaction>.
In the Transaction message, specify the following settings for each itinerary
you want to remove in the <Result> element:
- Set <Unavailable>with the reason child element, for example,<NoVacancy>.
- Set <Taxes>to "0"
- Set <OtherFees>to "0"
Optional: Set <Baserate> to "-1"
The following example removes several itineraries, for example, remove 1-night stays for several different dates for hotel "1123581321" from inventory:
<?xml version="1.0" encoding="UTF-8"?>
<Transaction timestamp="2023-05-23T16:20:00-04:00" id="42">
  <Result>
    <Property>1123581321</Property>
    <Checkin>2023-05-23</Checkin>
    <Nights>1</Nights>
    <Unavailable>
      <NoVacancy/>
    </Unavailable>
    <Tax currency="USD">0</Tax>
    <OtherFees currency="USD">0</OtherFees>
  </Result>
  <Result>
    <Property>1123581321</Property>
    <Checkin>2023-05-24</Checkin>
    <Nights>1</Nights>
    <Unavailable>
      <NoVacancy/>
    </Unavailable>
    <Tax currency="USD">0</Tax>
    <OtherFees currency="USD">0</OtherFees>
  </Result>
  <!---Sending <Baserate> is optional with <Unavailable> -->
  <Result>
    <Property>1123581321</Property>
    <Checkin>2023-05-25</Checkin>
    <Nights>1</Nights>
    <Baserate currency="USD">-1</Baserate>
    <Unavailable>
      <NoVacancy/>
    </Unavailable>
    <Tax currency="USD">0</Tax>
    <OtherFees currency="USD">0</OtherFees>
  </Result>
</Transaction>
As this example shows, you must explicitly set the <Unavailable> with the
reason for each itinerary (combinations of check-in dates and number of
nights) for which the room is unavailable. In addition, you must set the
<Taxes> and <OtherFees> to 0. Setting <Baserate> to -1 is optional.
To remove a Room Bundle, delete the <RoomBundle> element from the
<Result>.
