Enable

To enable Total TLS - which issues individual certificates for your proxied hostnames - follow these instructions:

Dashboard

To enable Total TLS in the dashboard:

1. Log into the Cloudflare dashboard ↗.
2. Choose your account and domain.
3. Go to SSL/TLS > Edge Certificates.
4. For Total TLS, switch the toggle to On and - if desired - choose an issuing Certificate Authority.

API

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.

Aspects to consider

• 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.
