Update for Openprovider API – Getting information about DCV validation

0 min read

According to the changes made by Comodo for DCV validation methods, we have updated returned values for API method retrieveOrderSslCertRequest.

The structure of the parameter additionalData is the following now:


There are new fields sha256, fileLocation and fileContents for HTTP(s) validation and dnsrecord and dnsValue for DNS type of validation.

For the cases when you use a previously used CSR for a reissue, renewal or new order, Comodo will add a unique value to the file contents or the DNS record to prevent that the old one is re-used without knowing. An example for a DNS record in such a case:


That is why we highly recommend you to use values returned in the new fields fileContents and dnsValue instead of generating values for DCV validation on your side.
