API Reference

How to get started with Slick

Welcome to Slick

The Slick API allows anyone to create, send and manage invoices and expenses for themselves or on behalf of their customers.

Slick was built from the ground up for developers, so if you have any feedback or find any bugs, we want to hear about them on [email protected]

Sending your first invoice

You can create and then send an invoice in 2 API calls. But we recommend doing a few other things first to make it easier to get things done in future.
