# SMX

Connect your application to SMX API to access reservation, availability, and rate data and be listed in the Hotel App Store.

SMX provides hotel applications with a single, standardised connection to the SiteMinder Platform and its network of PMS providers — delivering reservation data, modifications, cancellations, and guest check-in/check-out statuses in real time. Connected apps are listed in SiteMinder's Hotel App Store, giving direct access to thousands of hotel customers.

### Key Benefits

* **Single Integration:** Connect to multiple PMSs through one standardised API — no proprietary integrations required.
* **Data Access at Scale:** Receive real-time reservation data, guest statuses, modifications, and cancellations across all connected properties.
* **Hotel App Store Visibility:** Become discoverable by hotels and grow your customer base within SiteMinder's global ecosystem.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developer.siteminder.com/smx-api/smx-api.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
