After enabling the plugin, go to the API keys plugin management page, click `Add API key`, fill in the relevant information, and click Save to create an API key.
## Using an API key
Add the `Authorization` field to the request header, with the value of `Bearer ${API_KEY}`, to access all `NocoBase` APIs using the API key.
> Warning: When using the `Docker` image to use `NocoBase`, make sure you have configured the [APP_KEY](https://docs.nocobase.com/api/env#app_key) environment variable, otherwise the API key will be invalid after each restart.
