# Developer Sandbox

Set up the sandbox environment to allow building and testing in the testnet.

### Process:

1. Developers create a new API key of the sandbox environment through the production frontend Dashboard.&#x20;
2. Developers use the sandbox API key to access the sandbox API with the sandbox URL.&#x20;
3. The API for the sandbox environment needs to be verified by checking the sandbox secret key to access the sandbox environment.

Adding a whitelisted IP for the sandbox server is required, which is the only allowed access for the IP address of the production environment to terminate any unauthorized access.

#### Features:

* Show sandbox data on the Developer Portal
* Allows developers to test transactions in testnet without spending any real assets/funds during integration.
