Enable
To enable Total TLS - which issues individual certificates for your proxied hostnames - follow these instructions:
To enable Total TLS in the dashboard:
- Log into the Cloudflare dashboard ↗.
- Choose your account and domain.
- Go to SSL/TLS > Edge Certificates.
- For Total TLS, switch the toggle to On and - if desired - choose an issuing Certificate Authority.
To enable Total TLS with the API, send a PATCH
request with the enabled
parameter set to your desired setting (true
or false
).
You can also specify a desired certificate authority by adding a value to the certificate_authority
parameter.
-
Total TLS certificates follow the Common Name (CN) restriction of 64 characters (RFC 5280 ↗). If you have a hostname that exceeds this length, you can create an Advanced Certificate via API to cover it.
