API & webhooks
An API your team can actually build on
Every screen in Rentlica is powered by the same public REST API and webhooks you get. No shadow integration layer.

Versioned public API
Webhooks
Bookings, vehicles, agreements
OpenAPI
Interactive developer docs
The dashboard is a client of the same public REST API you get — versioned endpoints for vehicles, bookings, locations, and agreements, plus webhooks on record changes. API keys authenticate via Clerk; OpenAPI docs live at /docs. Rate limits and audit logs are included on the €59/month Business plan.
What you get on the desk
The same API we use
The dashboard is a client of the public API. You are not on a lesser integration path.
Webhooks for the events that matter
Bookings, vehicles, and agreements can notify your other systems when they change.
Docs that match the product
OpenAPI spec and interactive documentation so implementers are not guessing field names.
Rate limits and audit logs
Integrations stay observable. You can see who called what when something looks off.
