How to set up API Streaming of Mortgages

I want to set up an API to live stream registered and satisfied mortgages from Companies House (which CHS tell me is no problem with the right knowledge and know-how)
However, I do not know how to create an API to do this which is why CH have suggested that I post this topic on their forum.
Can anyone help with either creating an API to stream mortgage data from Companies House or pointing me in the right direction with software requirements.
We intend to import these mortgages into our CRM database.
