# configure

The `configure` command is used to configure CLI parameters, such as your API key.

Typically, you'd configure your API key upon initialization: `blocks init --key <api-key>`, but you'll use `configure` if blocks is already initialized and you need to update your key.

<CodeGroup>
  ```bash bash theme={null}
  blocks configure --key <api-key>
  ```
</CodeGroup>

You can also use `blocks configure` for an interactive experience.
