# Introduction

> An intro for showcasing Setle API endpoints

## Welcome

Welcome to the Setle API Reference. This section provides information on how to interact with Setle’s API endpoints. Here, you’ll find documentation on every endpoint, including request and response formats, parameters, authentication methods, and example calls.

## Getting Started

To begin using the Setle API, ensure you have your `Client Credentials` (client\_id + client\_secret) ready and refer to our [Authentication](/api-reference/authentication) section for instructions on how to retieve an access token with them. You can follow along with our [Quickstart](/quickstart) or dive straight into the API endpoints yourself!

## Support

If you have any questions or need further assistance, [our support team](https://setle.app/en/contact-us) is always here to help. Also if you are missing something in our documentation please let us know!
