# Authentication

To make API calls, an API key associated with a user who has the necessary permissions to perform the desired action in the selected workspace is required.

## Generating an API Key

To generate a new API key, navigate to Settings and User Settings. In the **API Key** section select the "Create" Button. The key will only be displayed at the time of creation, so ensure you save it in a secure location, as it cannot be retrieved later.

You can define an expiration date to an api key.
{% endhint %}

## Using the API Key

To authenticate your API requests, include the API key in the header using the following format:

**Headers**

| Name          | Value               |
| ------------- | ------------------- |
| Authorization | `Api-Key <API_KEY>` |
