# Testing REST API

You can test your custom chaincode REST APIs right from within the Spydra console. You can also test the APIs from any REST API client like Postman.

{% hint style="info" %}
The pre-requisite is that your custom app should already be deployed on a Network.
{% endhint %}

### 1. Create an API key

* Navigate to the Network
* Go to API key page from the Side menu
* Generate an API key for the Organization
* Copy the API key
