API & SDK built for the car rental software industry

Add Hannk to the rental software you already build.

Hannk gives car rental management software providers and operators a full API and SDK ecosystem for integrating digital rental, keyless mobile vehicle access, telematics, GPS intelligence and supported remote vehicle control — without replacing the core rental management system.

Built for integration

API, SDK and event-driven integration let software providers add Hannk capabilities to their own rental products.

One integration layer

Connect rental and vehicle workflows through Hannk rather than building separate integrations for every digital-rental capability.

API-led architecture

Exchange reservation, driver, vehicle, access and operational data between Hannk and existing rental platforms.

SDK integration

Use Hannk SDK components and integration tooling to accelerate implementation of supported customer and vehicle experiences.

Events & webhooks

Use event-driven workflows so changes in a rental or vehicle state can be reflected in connected systems.

White-label friendly

Software providers can keep their own interface and customer relationship while using Hannk technology behind the experience.

Modular or end-to-end

Integrate the capabilities you need or connect the complete digital rental journey.

For software producers

Make connected rental functionality part of your own platform

Hannk is designed for companies that develop rental management software as well as rental operators themselves. A software provider can integrate Hannk and expose digital rental, keyless access, telematics and vehicle-control capabilities through its existing product experience.

The objective is simple: your software remains the system your customer knows; Hannk supplies the connected rental technology underneath it.

Integration scope

From reservation events to the connected vehicle

The integration layer is designed around the entities rental software already understands: reservations, vehicles, authorised drivers, rental periods and branches. Hannk can then connect those records with digital access permissions, telemetry, location events, inspections and other digital-rental workflows.

Developer experience

Designed to reduce integration friction

Hannk provides API and SDK routes so integration teams can choose the approach that best fits their product architecture. Implementation scope depends on the functions being deployed, the target vehicle estate and the workflow required.

Frequently asked questions

Can an RMS provider integrate Hannk without replacing its software?

Yes. That is a core use case for the Hannk developer platform. Existing rental software can remain the primary operator interface while integrating selected Hannk services.

What can be integrated?

The ecosystem is designed to cover digital rental workflows, mobile/keyless vehicle access, telematics and GPS data, geofence and vehicle events, supported remote actions, inspections and associated rental events.

Do we have to integrate everything?

No. Hannk can be introduced as selected capabilities or as a broader connected digital-rental layer.

Does Hannk support event-driven integration?

Yes. The platform is designed to support API and event/webhook-driven workflows between Hannk and connected rental systems.
