What is a MARSHA code and how do I find the one for a specific property?

MARSHA (Marriott Automated Reservation System for Hotel Accommodations) codes are the 5-letter property identifiers Marriott uses internally for every hotel in its portfolio. You can find a property's MARSHA code from Marriott's own booking flows or property documentation. Pass the code as the property_id parameter to get_hotel.

Marriott has a developer program. Why would my team use Integuru for property data?

Marriott's official developer API access requires an approved partnership application and is scoped to specific use cases. Integuru provides an alternative path for teams that need hotel property data programmatically without going through a formal partnership process, and delivers results via the same direct HTTP request model as all other Integuru integrations.

Will the integration break if Marriott updates its website?

Frontend UI changes do not affect Integuru because the integration communicates directly with Marriott's backend HTTP endpoints. If an underlying endpoint changes, Integuru's 24/7 on-call team detects and repairs the integration automatically.

Overview

Integuru's Marriott integration provides production-ready HTTP API access to Marriott, the global hotel brand operating more than 30 brands across 140 countries, covering 1 action: get_hotel. The action takes a single required parameter, property_id, which is the 5-letter MARSHA (Marriott Automated Reservation System for Hotel Accommodations) code that uniquely identifies every property in Marriott's portfolio.

MARSHA codes are required. Marriott's property lookup is keyed on MARSHA codes, not on property names or addresses. You need the 5-letter code for the specific hotel you want to retrieve before calling this action.

Travel-tech engineers use this integration to pull structured property data for Marriott hotels programmatically without navigating the Marriott website or relying on manual lookups. Integuru connects via direct HTTP requests, delivering responses in under 3 seconds with a 99.9%+ success rate. See the TripleSeat integration for event and venue management in the hospitality sector, or browse the full integrations catalogue.

Use Cases

Integuru's Marriott integration lets you retrieve structured hotel property data for any Marriott property by its MARSHA code.

Property data retrieval: Call get_hotel with a 5-letter property_id (MARSHA code) to retrieve structured data for that Marriott property.

Setup Notes

Integuru's Marriott integration authenticates against https://www.marriott.com/. Integuru handles the login session automatically.

The get_hotel action requires a single parameter: property_id, the 5-letter MARSHA code for the target property. Marriott assigns a unique MARSHA code to every property in its portfolio. This code is distinct from hotel names or numeric identifiers. Locate the correct MARSHA code for your target property before calling the action.
