Update for Openprovider API – Getting information about DCV validation

In accordance with the changes made by Comodo for DCV validation methods, Openprovider has updated returned values for the API method retrieveOrderSslCertRequest.

The structure of the parameter additional data is now as follows:

This API update consists of three new fields that have been added:

• sha256, fileLocation and fileContents, for HTTP(s) validation.
• dnsrecord and dnsValue for DNS type of validation.

For these 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. They do this to prevent that the old one is re-used without knowing. You can see example for a DNS record in such a case below:

_c7fbc2039e400c8ef74129ec7db1842c.example.com CNAME c9c863405fe7675a3988b97664ea6baf.442019e4e52fa335f406f7c5f26cf14f..comodoca.com

This 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.
