How to get data from my OWN .NET Web API application to ZOHO CRM and insert or update the records periodically

Hi,
 I have a Query. I am looking to populate my custom model inside the ZOHO CRM by getting data from my own api such as https: samplewebsite.net/api/test. I need to repeat this operation periodically.

I need to see an example of how to do it. I also need information about a way to make it automatic.

My application is in .NET API with back end in SQL server hosted in azure. 

The response from my site is JSON



Thanks
