# Property Management System (PMS)

Your PMS sends availability, rates, and restrictions to SiteMinder, which distributes them across booking channels. Reservations created on those channels flow back to your PMS automatically.

> **API used:** 
>
> [**pmsXchange**](/pmsxchange-api/pmsxchange-api.md) - availability, rate and restriction updates, and reservation management.

{% hint style="success" %}
**PMS integrations require a pilot property before going live.**

A single property is connected to production to validate that everything works correctly in a live environment before scaling to additional properties.

### What you need to build

#### Core

Core functionality is required to go live and enables the essential data exchange required to go live.

* [Rooms and Rates (SM → PMS)](/pmsxchange-api/reference/rooms-and-rates/sm-to-pms.md)
* [Availability (PMS → SM)](/pmsxchange-api/reference/availability.md)
* [Reservations Push (SM → PMS)](/pmsxchange-api/reference/reservations/push.md) or [Reservations Pull (SM → PMS)](/pmsxchange-api/reference/reservations/pull.md)

#### Additional

Additional functionality extends your integration beyond core certification scope. These are not required to go live but are recommended to deliver a complete PMS integration.

* [Rates OBP or PDP (PMS → SM)](/pmsxchange-api/reference/rates/pms-to-sm.md)
* [Restrictions (PMS → SM)](/pmsxchange-api/reference/restrictions/pms-to-sm.md)
* [Payment Transaction Record](/pmsxchange-api/reference/payment-transaction-record.md)

#### **UltraSync&#x20;**<mark style="color:orange;">**Beta**</mark>

*Advanced bidirectional sync between PMS and SiteMinder.*\
\
UltraSync extends pmsXchange by enabling real-time updates in both directions. SiteMinder can push rates and restrictions to your PMS, and your PMS can upload reservations directly to SiteMinder.

{% hint style="warning" %}
**Prerequisite:** To implement UltraSync `Rates OBP or PDP (SM → PMS)` and `Restrictions (SM → PMS)`, you must first implement `Rates OBP or PDP (PMS → SM)` and `Restrictions (PMS → SM)` from the Additional functionalities tier above.
{% endhint %}

* [Rooms and Rates (PMS → SM)](/pmsxchange-api/reference/rooms-and-rates/pms-to-sm.md)
* [Rates OBP or PDP (SM → PMS)](/pmsxchange-api/reference/rates/sm-to-pms.md)
* [Restrictions (SM → PMS)](/pmsxchange-api/reference/restrictions/sm-to-pms.md)
* [Reservations Upload (PMS → SM)](/pmsxchange-api/reference/reservations/upload.md)
* [Reservations Import](/pmsxchange-api/reference/reservations/import.md)
