# Create API key

Creating an API key is necessary for using the Mattermix API. To create one, head to the *API* tab in your *Account* and click on the *Create key* button to create a new API key.

Once the new API key is created, a modal will open with the new key. For added security, this is the only time you can view the key, so copy the value and keep it in a secure place. **Treat your API key like a password and do not expose or share it with anyone**.

{% hint style="warning" %}
**Warning:** Delete your API key and create a new one if it is accidentally shared or exposed to the public.
{% endhint %}

You can now use your API key to [authenticate API requests](/api/authentication.md).
