# Introduction

> Get started with the Decisionly API to automate dispute filing

The Decisionly API is organized around [REST](https://en.wikipedia.org/wiki/REST). The API has resource-oriented URLs, accepts [JSON-encoded](https://www.json.org/json-en.html) request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

## Test Mode

You can use the Decisionly API in test mode, which doesn't affect your live data or interact with the card networks. The API key you use to authenticate the request determines whether the request is live mode or test mode.

## Getting Started

To get started:

1. Create a new API key from your [settings page](https://decisionly.com/settings)
2. Read the [Quickstart](/quickstart) guide to learn how to make your first request
3. Explore the API reference to learn about available resources and endpoints

## Base URL

All API requests should be made to:

```
https://api.decisionly.com/v2/issuer
```
