Public API documentation
Public API documentation
This is the official documentation for the QUiCK public API — the single source of truth for everything you need to build with our platform.
Whether you're integrating for the first time or looking up a specific endpoint, you'll find what you need here:
Check the connection, identify your company and upload an expense document — in about five minutes.
Create an API token and learn how to send it with every request.
Browse every endpoint, request and response shape, straight from the OpenAPI contract.
See what changed in the public API over time.
Look up what an API field or concept means, in Hungarian or English.
This documentation is a work in progress, and new sections are being added regularly. What's already published has been carefully reviewed, so you can rely on it as you build.
