Where can I find a description of the document format for extracting from the FSIS USRN?

Question

SOAP

We need to automate the process of obtaining an extract from the FSIS USRR through the Rosreest web service, which is talked about everywhere, but there is no information describing the direct interaction protocol.
Interaction through third-party services providing the Rosreest API is known to us, but is not suitable.
We have not been able to receive a response from the registry for the fifth day already.
It would be great to find more or less complete information on the entire interaction process, since the only starting point of which we currently have is this document https://rosreestr.ru/site/upload/documenty/doc_doc... which describes general details of interaction, but there is no information on the format of the document (for a request) for obtaining an extract from the USRN.
The document itself with a description of the protocol was described before the formation of the USRN (maybe someone knows a more up-to-date source with a description of the protocol?).
We are interested in the trace. information:

• Where can I find the most up-to-date information about the Direct Interaction Protocol (or do we use the most up-to-date one available)?
  
• Where can I find the document format for generating a request for an extract from the USRN?
  
• How to automate the encryption process (the given document describes the manual execution of this process in Appendix #2 using the CryptoARM program). I found this instruction https://armrus.org/extranet/forum-egrn-kluba/index... (is it fair in our case?).
  

For help with the difficulties that have arisen (due to the lack of information), we express modest, financial gratitude.

Answer 1

There is some information on the FSIS USRN API. Is your question still relevant?
On the Rosreestr website itself, we managed to find the following:
Agreement on interaction when the User connects to the web services of Rosreestr and on the conditions for using the services and systems of Rosreestr: https://rosreestr.ru/upload/Doc/10-upr/%D0%A1% D0%B...
Instructions for connecting to Rosreestr web services: https://rosreestr.ru/upload/Doc/10-upr/%D0%98%D0%B...
Rules for interaction with FSIS USRN via web services (API description): https://rosreestr.ru/upload/Doc/10-upr/%D0%9F%D1%8... The
information is dated 2018, that is, in theory it should be up to date.
What is missing for completeness is that since SOAP is used, descriptions of xml request schemas are needed. I found them, but I'm not sure of their relevance.
I have an e-mail in my contacts. If you have any questions, write, I will be happy to discuss this topic, since I myself am now puzzled by it)
