# API Keys



Every request to the Surface API needs an API key. A key is scoped to one environment and can reach every resource in that environment.

## Creating an API Key [#creating-an-api-key]

1. Log in to your Surface account.
2. Go to **Settings** > **API Keys**.
3. Click on **+ Add API Key**.
4. Give your key a name and click **Create**.
5. **Copy and note down the API key** immediately, as it won't be shown again.

<Warning>
  A key is shown once, when you create it. Store it somewhere secure. If you lose it, create a new one.
</Warning>

## Using Your API Key [#using-your-api-key]

Include your API key in the `x-api-key` header for all API requests:
