# API Keys

An API Key is a unique identifier that allows your applications to access specific issuance and verification templates via the Gataca Studio APIs.

### Create an API Key 

1. Go to the **"API Keys"** section in the left menu and click **"Create API Key."**
2. Configure the API Key:

* **API Key Name**: Choose a name for your API Key.
* **DID**: Select the DID associated with the API Key. This determines which administrators can access it.
* **SSI Operations**: Select the credential issuance template you want to link to this API Key.
