Connect Your World to Rental Ninja: Introducing the Client API

Do you use multiple tools to run your rental business? A channel manager here, a pricing tool there, maybe a custom website or an in-house system built just for your operation? If so, you've probably felt the friction — data that doesn't sync, manual exports, workflows that break the moment something changes. What if your tools could just talk to Rental Ninja directly? That's exactly what the Rental Ninja Client API is built for.

What Is the Client API?

The Client API is a programmatic interface that gives you — or your tech team — direct access to your Rental Ninja data. Instead of logging into the platform to check availability or export bookings, you can connect any external system to Rental Ninja and automate the exchange of information in real time.
Think of it as a direct line between Rental Ninja and the rest of your world.
It's built on industry-standard technologies (OAuth 2.0 authentication, HTTPS, JSON responses) and designed to be straightforward to integrate — whether you're a property manager working with a developer, a software company building on top of Rental Ninja, or an enterprise running a custom tech stack.

When your system does X, Rental Ninja knows about it. When Rental Ninja knows Y, your system reacts.
That's the power of an open API.

**What Can You Actually Do With It?**

The API is organized around four core capabilities. Here's what each one unlocks in practice.

1. Rentals Management — Your Properties, Always in Sync

List all your properties and pull full details: name, currency, pricing range, minimum stay, booking window, fees. Anything you see in Rental Ninja, your systems can see too.

Practical example: Your custom website always shows up-to-date property info — no manual updates, no outdated descriptions. The moment you change something in Rental Ninja, it's reflected everywhere.

2. Pricing & Availability — Push Your Own Rates

This is where things get really interesting for operations running dynamic pricing. You can read and write daily pricing data for up to 3 years ahead: nightly rates, extra guest charges, minimum stay per day, and check-in/check-out restrictions.

Practical example: You run your own revenue management logic — maybe a custom algorithm, maybe a spreadsheet-driven model — and you want those prices to live in Rental Ninja automatically. With the API, you push your rates directly, and Rental Ninja applies them. No copy-pasting. No human error.

The first time you update pricing via the API, Rental Ninja automatically sets your pricing model to 'api' for that property — a clean handoff from manual to automated.

3. Bookings Access — All Your Reservation Data, Your Way

Pull all your bookings with powerful filters: by status, by channel (Airbnb, Booking.com, direct...), by date range, by property. Each booking response includes everything — guest details, pricing, fees, taxes, commissions, and timestamps.

Practical example: Your accounting software automatically pulls confirmed bookings each night. Your CRM gets notified when a new reservation comes in. Your operations dashboard shows real-time occupancy across all properties. All of this without anyone lifting a finger.
It's read-only, which means your data stays safe — no accidental edits from external systems.

4. Booking Engine — Build Your Own Booking Experience

This is the most powerful module. With the Booking Engine API, you can build a fully custom booking flow — your own design, your own brand, your own UX — while Rental Ninja handles everything underneath.

The flow works like this:

  1. Search available properties for given dates and guests
  2. Get check-in dates available for a specific property
  3. Get check-out dates based on the selected check-in
  4. Request a quote — a full price breakdown including all fees and taxes
  5. Reserve — create the booking and redirect the guest to Stripe for payment
  6. Confirm — handle the success or cancellation result

Practical example: You have a direct booking website with your own design. Instead of embedding a generic widget, you build the entire experience your way — search, results, calendar, pricing summary, checkout — and the API does the heavy lifting. Your brand, your flow, Rental Ninja's engine.

Who Is This For?

The Client API is especially valuable for:

  • Property managers with custom websites who want a fully branded booking experience without relying on third-party widgets
  • Companies using external pricing tools who need to push rates directly into Rental Ninja
  • Operations teams running their own dashboards who want live booking and occupancy data
  • Software developers and integrators building products on top of Rental Ninja
  • Enterprise and franchise operations managing large portfolios who need system-to-system automation

If you've ever thought "I wish Rental Ninja could just connect directly to our system" — this is the answer.

Getting Started

Getting access is straightforward. You'll receive a Client ID and a Client Secret from Rental Ninja, which you exchange for an access token (valid for one year). From that point, every API request is a standard HTTPS call with that token in the header.

The API supports up to 300 requests per minute, includes clear error codes for every scenario, and returns consistent, well-structured JSON responses. Full documentation is available at docs.rental-ninja.com.

If you're a developer, you'll feel right at home. If you're a property manager working with a developer or tech partner, this gives them everything they need to build a solid integration.

The Bigger Picture

Every feature we build at Rental Ninja is aimed at the same goal: giving you more control over your operation, and freeing you from tasks that shouldn't require your attention.
Triggers let you automate your communications. Smart Pricing optimizes your rates. The Client API opens the door to connecting Rental Ninja with every other tool in your stack — so that your entire operation works as one, not as a collection of disconnected pieces.
