# Booking tracking

[](#)  [ API reference ](https://documentation.netstorming.net/api-reference)     [ Hotels ](https://documentation.netstorming.net/api-reference/hotels)     [ Bookings ](https://documentation.netstorming.net/api-reference/hotels/bookings)      Booking tracking    

Once the booking request has been sent, and once the feedback has been received by the client system, the system will keep up to date the client back-end using **tracking** messages.

In this case is the **TOWeRS** system that will contact the client one sending tracking messages to the requested URLs. If the response mode has been set to xml then the tracking message has the following structure:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<envelope>
    <header>
        <version>1.7.2</version>
        <timestamp>20250901101327</timestamp>

                <pax title="MR" initial="G" surname="ROSSI" age="5"/>
                <prices>

                    <extrabedprice nett="40.25"/>
                    <cotprice nett="10.00"/>
                </prices>
            </room>
        </details>
 </query>
</envelope>
```

The **type** attribute has been set to the **track** value. The heading does not contain any user or password details in order to avoid that, if the wrong URL is passed, those data are not shared with some third parts. There are more tags here compared with availability response and booking request.

The **supplier** tag reports the name of the supplier of the hotel and the referece number in **code** attribute: it has to been reported in the voucher unless retrieved from the **TOWeRS** system.

The **invoiced** tag reports, in its **by** attribute, the code of the office that will issue the invoice bound to the referred booking; the current existing office codes will be listed in a specific document.

The **booking** tag reports in its **code** attribute the booking number in the **TOWeRS** system. Those references must be used later to cancel the booking. The **status** tag reports the status value in its **code** attribute. Possible values for status are:

- **pnd** for pending;
- **cnf** for confirmed;
- **cxl** for cancelled;
- **rej** for rejected

The **deadline** tag reports, in its **date** attribute, the day within you won't be charged.

Tag **prices** are usually present only with **cnf** status. In other statuses those details could not be present yet or they could have been already removed.

**Please note** that the **reference** tag can optionally contain a new attribute, **hcn**, wich reports the Hotel Confirmation Number (if available).
