HTNG (Hotel Technology Next Generation)

HTNG (Hotel Technology Next Generation) is a non-profit trade association and standards body that develops open technology specifications for the hospitality industry. Founded in 2002 and later aligned with the American Hotel & Lodging Association (AHLA), HTNG brings together hoteliers, technology vendors, OTAs, and system integrators to create interoperability standards that reduce the cost and complexity of connecting hotel technology systems.

What HTNG does

HTNG organises industry workgroups that produce open technical specifications across areas including:

• PMS-to-channel connectivity — protocols for passing availability, rates, and restrictions (ARR) between Property Management Systems, Channel Managers, and CRS platforms
• PMS-to-POS integration — standards for posting restaurant, spa, and parking charges to guest folios
• Loyalty and guest profiles — formats for transferring guest history and membership data between brands, properties, and third parties
• Cybersecurity — guidelines for securing guest-facing systems and payment environments in line with PCI DSS requirements
• Contactless and mobile services — specifications for digital key, mobile check-in, and in-room technology

Why it matters

Before open standards existed, connecting a hotel's PMS to a CRS, channel manager, or OTA required expensive bespoke integrations that could take months to build and were fragile to maintain. HTNG specifications — alongside those from the OpenTravel Alliance — provide a common technical language that reduces integration time, lowers switching costs for operators, and encourages a more competitive vendor ecosystem.

For OTAs and distribution platforms, HTNG-compliant hotel partners deliver more accurate real-time inventory, rate, and restriction data, which directly reduces overbooking risk and improves the guest experience on the platform. For hotel operators, compliance with HTNG standards makes it easier to adopt new technology without full re-integration.
