# API Reference

> Complete reference for the Atlas Payment API

The Atlas API is organized around REST. Our API has predictable resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

## Base URL

All API requests should be made to:

```
https://api.atlaspay.cc/functions/v1
```

## Authentication

The Atlas API uses API keys to authenticate requests. You can view and manage your API keys in the [Dashboard](https://atlaspay.cc/dashboard/api-keys).

Include your API key in the `Authorization` header:

```bash theme={null}
Authorization: Bearer sk_test_your_api_key
```
