API Token The preferred authorization scheme for interacting with the Cloudflare API. Create a token. **Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY
API Email + API Key The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key. **Example:**X-Auth-Email: user@example.com The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys. **Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194
