The environment variable names can be suffixed by `_FILE` to reference a file instead of a value.
More information [here](/lego/dns/#configuration-and-credentials).
The Global API Key needs to be used, not the Origin CA Key.
## Description
You may use `CF_API_EMAIL` and `CF_API_KEY` to authenticate, or `CF_API_TOKEN`.
### API keys
If using API keys (`CF_API_EMAIL` and `CF_API_KEY`), the Global API Key needs to be used, not the Origin CA Key.
### API tokens
If using [API tokens](https://api.cloudflare.com/#getting-started-endpoints) (`CF_API_TOKEN`), the following permissions are required:
* `Zone:Read`
* `DNS:Edit`
