This endpoint can be used to retrieve a DigiCert Order associated with a certificate, provided there is a working DigiCert CertCentral integration in place. When invoked, we look for the order information using the CertCentral API. If we obtain a response, this endpoint will pass through the results back in its response. The full documentation for the response is available in DigiCert's API documentation.
Please note that, before invoking the CertCentral API, we can't tell if a certificate is the configured DigiCert account. If it's not, you will see a 404 response. We have also noticed that CertCentral sometimes responds with a 503 status code for a certificate that resides in someone else's account. That might happen if you attempt to fetch order information for a managed/third-party certificate issued by DigiCert. We try to detect this case early by checking the certificate before talking to CertCentral.
There is no caching of order information at present, but we anticipate that it will be added in a future release.
