ACME External Account Binding

POST https://www.digicert.com/services/v2/key/acme-eab

Use this endpoint to generate a key identifier and HMAC key for ACME External Account Binding (EAB). Use these credentials with an ACME client that supports EAB (like CertBot) to automate the deployment of OV or EV TLS/SSL certificates.

Danger

We only display your EAB credentials once. You cannot recover lost EAB credentials. If you lose access to your credentials, you must regenerate them.

Certificates with the CanSignHTTPExchanges extension

If the certificate profile option (see Certificate profile options) for HTTP Signed Exchange is enabled for your CertCentral account, you can use ACME to automate deployment for certificates with the CanSignHTTPExchanges extension. For most accounts, this certificate profile option is not enabled by default. To enable this option, contact your account representative or the Support team.
