Container for the parameters to the ImportCertificateAuthorityCertificate operation. Imports a signed private CA certificate into ACM Private CA. This action is used when you are using a chain of trust whose root is located outside ACM Private CA. Before you can call this action, the following preparations must in place:

  1. In ACM Private CA, call the CreateCertificateAuthority action to create the private CA that that you plan to back with the imported certificate.

  2. Call the GetCertificateAuthorityCsr action to generate a certificate signing request (CSR).

  3. Sign the CSR using a root or intermediate CA hosted either by an on-premises PKI hierarchy or a commercial CA..

  4. Create a certificate chain and copy the signed certificate and the certificate chain to your working directory.

The following requirements apply when you import a CA certificate.
