# How do I use the OpusDNS sandbox to test the API?

## Using the OpusDNS Sandbox for API Testing

**The OpusDNS Sandbox** is a completely separate environment where you can safely test our API and dashboard **at no cost and with zero risk**. It’s ideal for integrating your system with OpusDNS and experimenting with features before using the live production environment. ([Learn more](https://help.opusdns.com/what-is-the-opusdns-sandbox-environment-and-why-should-i-use-it?hsLang=en))

#### 1. Creating a Sandbox Account

You can create a free OpusDNS sandbox account by registering at [app.sandbox.opusdns.com/signup](https://app.sandbox.opusdns.com/signup).

Once registered, you will have access to a sandbox dashboard at [app.sandbox.opusdns.com](https://app.sandbox.opusdns.com) which is similar to the production system (app.opusdns.com) and operates entirely within the isolated sandbox environment.

#### 2. Accessing the Sandbox Dashboard

Your sandbox dashboard at [app.sandbox.opusdns.com](https://app.sandbox.opusdns.com) allows you to:

- [Create an API Key](https://help.opusdns.com/how-do-i-generate-an-api-key-to-use-the-opusdns-api?hsLang=en) for testing. Please make sure to **save your API Key credentials**<https://help.opusdns.com/how-do-i-generate-an-api-key-to-use-the-opusdns-api?hsLang=en>
- Test API actions such as domain creation and transfers, as well as all associated services
- Monitor the impact of your API usage
- Explore the dashboard UI without impacting your actual domain inventory

#### 3. Using the Sandbox API

After registering your sandbox account and [generating a sandbox API key](https://help.opusdns.com/how-do-i-generate-an-api-key-for-the-sandbox?hsLang=en), you can refer to our **API reference at** [developers.opusdns.com](https://developers.opusdns.com).

The sandbox and production environments share the **same API code base**, but differ in the **base URL** used for API requests.

To ensure your requests are sent to the sandbox environment, use the following **base URL** (you can also select this URL at the top of the API reference):

`https://sandbox.opusdns.com`

Since the production and sandbox environments use similar dashboards and the same API, always double-check **which system you are working in** before performing any action. When using the API, make sure to **verify your current base URL** to ensure your requests are sent to the sandbox environment.
