Quick Start
Everything you need to begin building with SiteConnect API.
SiteConnect connects your booking channel with SiteMinder's distribution platform. Through SiteConnect, your channel can provide room type and rate plan mapping configuration, receive availability, restrictions, and rates from SiteMinder, and push reservations, modifications, and cancellations.
API Components:
Configuration: Rooms and Rates
Inventory: Availability, Restrictions, Rates (PDP and OBP)
Reservations: Push
Explore all components in the API Overview.
Before You Begin
Partnership Required
Access to SiteConnect requires an active partnership agreement with SiteMinder. Once your agreement is in place, you will receive your test environment details.
You don't need to wait for your test environment to start development. You can begin building and testing immediately. See Make Your First Call below or explore requests directly in the Postman collection.
What You'll Provide to SiteMinder
Before SiteMinder can set up your test environment, provide the following:
Inventory SOAP endpoint
Your HTTPS endpoint URL for Rooms and Rates, Availability and Restrictions, and Rates
Credentials
username and password for SiteMinder to authenticate against your Inventory SOAP endpoint
Hotel Code
HotelCode
What You'll Receive from SiteMinder
Once SiteMinder has received your details, we will provide:
Reservation SOAP endpoint
Credentials
username and password
Identifier
RequestorID (Channel Code)
Hotel Test Account
Platform that includes pre-configured room types and rate plans, an inventory simulator to push availability, restrictions, and rates, and to verify pushed reservations.
Set Up Your Environment
Authentication
SiteConnect uses channel-level authentication — one set of credentials covers all properties. Credentials are passed via wsse:UsernameToken for SOAP requests.
API Specification Files
SOAP (WSDL)
Inlined (recommended for .NET): https://tpi-cm-siteconn.preprod.siteminderlabs.com/reservation-gateway/services/siteconnect_v1.1.0_inlined.wsdl
Use the inlined WSDL for .NET clients — the standard version may cause issues with wsdl.exe or svcutil.exe due to OTA specifications.
Make Your First Call
The first component every SiteConnect integration must implement is Rooms and Rates — SiteMinder calls your endpoint to retrieve the room type and rate plan mapping configured in your system for a given property. This mapping is the foundation for all subsequent inventory and reservation operations.
SiteMinder initiates this call — your endpoint must be live, accepting incoming requests, and returning a valid room and rate configuration in the response before we can set up your dedicated test environment.
Validate credentials
Your endpoint must validate the wsse:UsernameToken on every incoming request. If the credentials do not match, return the following error response:
Invalid Username and/or Password — Return this error when the wsse:Username and wsse:Password in the incoming request do not match your configured credentials.
Validate hotel code
Your endpoint must verify that the HotelCode in the request matches a property configured in your system. If not found, return the following error response:
Hotel not found for HotelCode=XXXXXX — Return this error when the HotelCode in the incoming request does not match any property configured in your system.
You're ready for the next step. Once your endpoint handles the scenarios above, share with us your endpoint URL, credentials, and hotel code. We'll set up your dedicated test account to continue development.
Explore with Postman
SiteMinder's SiteConnect Postman workspace contains collections and environments to help you build, test, and validate your integration for certification. Fork the collections and environments to your own Postman account to get started.
