Official API

Does SiteMinder have an official API?

SiteMinder has APIs, but the ones that change rates, availability and restrictions or deliver reservations are for technology partners who sign a partnership agreement and certify each API (checked 11 Oct 2026). A hotel can generate its own key only for the read-only Direct Booking API.

Common use cases

What can an AI agent do in SiteMinder?

Cotlet is best for independent hotels and small groups without a certified PMS or RMS who want their AI agent to change rates, restrictions and availability and read reservations and reports without running or fixing a server.

Update rates for busy dates

The city marathon is on 6 and 7 December. Raise every base room rate by 25% for 5 to 7 December on all channels, but keep the Standard Double at no more than 210. Your agent calls list_room_rates, get_inventory and update_rates.
Set minimum stay and closed to arrival for peak dates

For Christmas, close all room rates to arrivals on 24 and 25 December and set a 3-night minimum stay from 23 to 27 December on every channel that supports it. Your agent calls list_channels, list_room_rates, update_restrictions and close_dates.
Fill gap nights between bookings Runs: Daily

Every morning, find single and two-night gaps between bookings in the next 60 days that our minimum stay blocks, and lower the minimum stay on those nights so they can sell. Your agent calls list_room_rates, get_inventory, list_channels and update_restrictions.
Daily arrivals list from SiteMinder Runs: Daily

List every reservation checking in tomorrow, with channel, room and total, as a table. Your agent calls list_reservations and get_reservation.
Weekly channel performance and pace report Runs: Weekly

Every Monday, compare last week's bookings by channel with the week before, and tell me how the next 30 days pace against last year. Your agent calls get_booking_performance, get_pace_report and get_rate_parity.
Close rooms and dates when rooms go out of order

We have a burst pipe in rooms 201 to 204: drop Standard Double availability by 4 for the next two weeks. Your agent calls get_inventory, update_availability and close_dates.
Check rate parity across OTAs Runs: Weekly

Check rate parity for the next 30 days and tell me where Expedia undercuts our direct rate. Your agent calls get_rate_parity.

Endpoints

What is the SiteMinder API?

Cotlet's SiteMinder API exposes 12 endpoints for your own SiteMinder account: list room rates, list channels, get inventory, list reservations, get reservation, get booking performance, get pace report, get rate parity, update rates, update availability, update restrictions and close dates. The list_room_rates endpoint returns room types and their room rates, with derived rates and the channels each one is mapped to. Each endpoint takes simple JSON inputs like from, to or room_rate_ids and works both as an MCP tool for agents and as a REST call for scripts.

POST

list_room_rates

Room types and their room rates, with derived rates and the channels each one is mapped to.

read

Returns every room type with its room rates. A derived rate shows the base rate it follows; SiteMinder does not let you set derived rates by hand. Use the IDs from here in get_inventory and the update tools.

POST /api/v1/siteminder/list_room_rates

Input

No parameters.

POST

list_channels

Connected booking channels with status and the data each channel rate supports.

read

read

Returns what the inventory grid shows, one row per date: rate, availability and restrictions for each room rate. Pass channel to see the values sent to one channel instead. SiteMinder shows only today and future dates here. A dash in the grid, returned as null, means the channel rate does not support that data.

POST

update_rates

Set the rate for room rates or channel rates over a date range. Goes live on mapped channels.

asks first write

Sets one nightly rate for the room rates you list, on all mapped channels or only the channels you name. Derived rates cannot be set; they follow their base rate by their own rules. Channels receive updates only inside their maximum update period. If a two-way PMS, RMS or CRS sends rates to SiteMinder, it overwrites this change. Large updates can take a few minutes. By default you confirm each call; you can switch that off for this tool.

POST /api/v1/siteminder/update_rates

Input

Input: update_rates
Parameter	Type	Description
room_rate_ids required	string[]	Room rate IDs from list_room_rates.
from required	date	First date of the range. Today or later.
to required	date	Last date of the range.
rate required	string	New nightly rate, as a decimal in the property currency.
channels	string[]	Only these channels. Default: the room rate for all mapped channels.
days_of_week	string[]	Only these weekdays (mon, tue, wed, thu, fri, sat, sun). Default: all days.

POST

update_availability

Set the number of rooms to sell per room type over a date range, for all channels.

asks first write

Sets rooms available per night for a room type. SiteMinder manages availability at room type level, so it applies to every channel; to limit one channel, use close_dates or update_restrictions. Availability 0 closes the whole room type and all its rates. If a two-way PMS, RMS or CRS sends availability to SiteMinder, it overwrites this change. By default you confirm each call; you can switch that off for this tool.

POST /api/v1/siteminder/update_availability

Input

Input: update_availability
Parameter	Type	Description
room_type_ids required	string[]	Room type IDs from list_room_rates.
from required	date	First date of the range. Today or later.

POST

update_restrictions

Set stop sell, minimum or maximum length of stay, closed to arrival or closed to departure.

asks first write

Sets the restrictions you pass for the room rates and dates you give, on all mapped channels or only the channels you name. Set stop_sell, cta or ctd to false to remove them. Not every channel rate supports every restriction; unsupported ones are listed under skipped. A connected two-way PMS, RMS or CRS overwrites restrictions set in SiteMinder. By default you confirm each call; you can switch that off for this tool.

POST /api/v1/siteminder/update_restrictions

Input

Input: update_restrictions
Parameter	Type	Description
room_rate_ids required	string[]	Room rate IDs from list_room_rates.
from required	date	First date of the range. Today or later.
to required	date	Last date of the range.
restrictions required	object	Any of stop_sell, cta, ctd (boolean), min_los, max_los (integer).
channels	string[]	Only these channels. Default: all mapped channels.

asks first write

Applies a stop sell for the dates you give: to every room rate, to the room rates you pick (all their channel rates close), or to one channel. Other rates and channels stay open. To reopen, call update_restrictions with stop_sell set to false. A connected two-way PMS, RMS or CRS overwrites stop sells set in SiteMinder. By default you confirm each call; you can switch that off for this tool.

Setup

How do I connect SiteMinder to Claude Code, Codex or Cursor?

Connecting SiteMinder takes three steps: request access, sign in to SiteMinder once, then add one MCP server or call the REST API with the same key.

MCP REST API

1
Create an account

Sign up and add SiteMinder in the console. Your API key is there too.
2
Sign in to SiteMinder once

Open the connect page from the console and sign in to SiteMinder the way you always do. We keep the session, never your password, and you can revoke it anytime.

Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

Ask your agent
Prompt
```
The city marathon is on 6 and 7 December. Raise every base room rate by 25% for 5 to 7 December on all channels, but keep the Standard Double at no more than 210.
```
Ask in plain words. Your agent finds the SiteMinder tools on the server and calls them for you; anything that reaches other people waits for your OK unless you switch that off for a tool.

Export your API key
Shell
```
export COTLET_API_KEY="cotlet_..."
```
Your scripts use the same API key as your agent. Keep it in an environment variable, never in your code.

Alternatives

Is there a SiteMinder MCP server on GitHub?

SiteMinder publishes no MCP server (checked 11 Oct 2026). A hotel without a certified PMS or RMS changes rates in the inventory grid or Bulk update, reads the Reservations tab and Insights reports, and downloads reservations as CSV by hand.

Reservations and reports	Filter the Reservations tab, download CSV, open Insights	Your agent reads reservations, booking performance, pace and parity as data
When SiteMinder changes	You learn the new screens	Our team tests it daily and fixes it for you; failed calls are free
Your SiteMinder session	Your browser, signed in by you with MFA; when it expires you sign in again	Encrypted in an EU vault, limited to the actions you allow, revoked in one click; if it expires, your agent gets a link to sign in again

siteminder.txt

SiteMinder has APIs, but the ones that change rates, availability and restrictions or deliver reservations are for technology partners who sign a partnership agreement and certify each API (checked 11 Oct 2026). A hotel can generate its own key only for the read-only Direct Booking API.
Cotlet provides a hosted MCP server and REST API for SiteMinder: 12 tools (8 read, 4 write).
Access       Request access at https://cotlet.dev/app/signup?app=siteminder; we email the API key.

MCP server   https://cotlet.dev/mcp/v1
REST base    https://cotlet.dev/api/v1/siteminder
Auth         Authorization: Bearer <COTLET_API_KEY>. Listing endpoints and schemas needs no key; calling an endpoint needs one.
Tools        list_room_rates, list_channels, get_inventory, list_reservations, get_reservation, get_booking_performance, get_pace_report, get_rate_parity, update_rates, update_availability, update_restrictions, close_dates
Confirm      update_rates, update_availability, update_restrictions, close_dates (by default the user approves each call; the user can switch this off per tool, e.g. for scheduled automations)
Markdown     https://cotlet.dev/integrations/siteminder-api-mcp-server.md

How access works:
1. The user requests access at https://cotlet.dev/app/signup?app=siteminder (SiteMinder is pre-selected). Each request is reviewed and the API key is sent by email.
2. The user signs in to SiteMinder once in a browser. An agent cannot do this step.
3. The API key goes into the MCP client or the REST call as a bearer token.

Fits: people who want a hosted SiteMinder server that someone else maintains, including non-developers.

Policy: Cotlet never stores passwords, never solves CAPTCHAs, never bypasses MFA.
Company: legal details in the Terms of service at https://cotlet.dev/terms. Contact contact@cotlet.dev.
Session: the user signs in to SiteMinder in a browser; Cotlet keeps only the session, AES-256 encrypted, revocable in the dashboard at any time.
Terms: the user stays responsible for following SiteMinder's terms; Cotlet is not affiliated with SiteMinder.

Automations

Can SiteMinder automations run on a schedule in n8n, Make or Zapier?

Yes. Cotlet does not replace your automation platform: it gives it a SiteMinder connection it does not have, with the same API key as your agent. Write actions ask for your OK by default; switch that off in your dashboard for the tools you choose, for example to fill gap nights between bookings, and the schedule runs on its own. Cotlet runs in the cloud, so it keeps going while your computer is off.

Where to run SiteMinder automations through Cotlet, and how to schedule them
Where	How to connect	How to schedule
Your AI agent	Add https://cotlet.dev/mcp/v1 with your API key.	A scheduled agent run, for example a Claude Code routine.
n8n	MCP Client node with https://cotlet.dev/mcp/v1, or an HTTP Request node to https://cotlet.dev/api/v1/siteminder/{tool}.	Schedule Trigger node.
Make	HTTP module: POST https://cotlet.dev/api/v1/siteminder/{tool} with an Authorization: Bearer header and a JSON body.	Scenario schedule.
Zapier	Webhooks by Zapier: POST https://cotlet.dev/api/v1/siteminder/{tool} with the same header and body.	Schedule by Zapier trigger.
Your own script	POST https://cotlet.dev/api/v1/siteminder/{tool} with your API key.	cron or GitHub Actions.

About Cotlet

Company details: The legal name, address and registration numbers of the company behind Cotlet are in the Terms of service. Terms
Your session: You sign in to SiteMinder yourself, in your browser.

What we never do: Store passwords, solve CAPTCHAs or bypass MFA.

About Cotlet

Frequently asked questions

How do I get access?

Request access and pick SiteMinder. Cotlet reviews each request and emails you your API key.

Do I need to be technical?

No. You sign in to SiteMinder once in your browser and paste one command into your agent, or one URL into n8n. Your agent can walk you through it. There is no server to install, update or fix.

Is a hosted server safe? My SiteMinder session would leave my computer.

Cotlet keeps your SiteMinder session encrypted with AES-256 in an EU vault, isolated to your account and used only for the tools you allow: read only, or read and write. The AI model never sees it, and you revoke it in one click. A local server keeps the same session in a file on your computer, readable by any program you run, and needs a fresh sign-in whenever it expires.

Does it work if my hotel has a connected PMS or RMS?

Reads work either way. For changes, SiteMinder says a two-way PMS, RMS or CRS overwrites manual updates in the inventory grid, so rates, availability and restrictions are changed in that system. Cotlet changes the same grid you do, so use the write tools only for data your PMS does not sync.

Can it cancel or change a channel reservation?

No. SiteMinder says channel bookings from Booking.com, Expedia and other OTAs cannot be cancelled in the platform; the guest or you must cancel at the channel. Cotlet reads reservations and does not change them.

Does it return guest emails, phone numbers or card details?

No. Since 22 Sep 2026 SiteMinder shows guest contact and card details, and allows reservation downloads, only on a trusted device (SiteMinder Help: Trusted devices). get_reservation leaves those fields out.

Can my agent post or send messages in SiteMinder without asking me?

No. Every call to update_rates, update_availability, update_restrictions or close_dates waits for your OK by default. For scheduled automations you can switch confirmation off per tool in your dashboard, for example only for approvals.

Can I use the SiteMinder API in n8n?

Yes. Add https://cotlet.dev/mcp/v1 with your API key in n8n's MCP Client node, or call https://cotlet.dev/api/v1/siteminder/{tool} from the HTTP Request node.

Give your agent access to SiteMinder.
