Hotel PMS API. Open REST API for Developers

Open API

Pick any tool. Own your data. Build exactly what your hotel needs.

Your hotel runs on a dozen tools. Make them work as one.

Connect Yanolja Cloud Solution to the systems your team already uses. 650+ integrations are live today, from channel managers to accounting to payments. Or build your own, with documented endpoints, a free sandbox, and sample code that runs the first time.

One API. Your whole stack connects through it.

The tools your hotel runs on connect through a single API. Yanolja Cloud Solution runs your PMS, channel manager, booking engine, and POS. Everything else you use plugs into the same connectivity layer.

Built on one platform. Open to your stack.

Four APIs. Everything partners build on.

Connectivity API

Bookings, rates, inventory, guest profiles, housekeeping, financials. Read and write, both ways.

Channel Manager API

Push to OTAs and metasearch. Pull bookings from connected channels. Rates, restrictions, availability.

Booking Engine API

Power direct bookings on your own widget. Availability, packages, promotions, payments.

POS API

Menu, orders, sales, vendor purchases. Modern REST. One café or twenty outlets.

Full capability details: Read, create, and update by module in the developer docs

Per-property credentials. Yours to rotate, restrict, or revoke.

Every integration connects with its own API key, scoped to your hotel. TLS 1.2 or higher on every request. Rotation, IP restrictions, and revocation built in. Full mechanics in the developer docs.

Booking events, pushed to your endpoint.

New booking. Modification. Cancellation. Yanolja Cloud Solution pushes the event to your endpoint automatically. No polling. No batch jobs. Your partner systems stay in sync.

Proven where it matters.
