AWS IoT Rule - HTTP Destinations Authentication

Question

I have an IoT project where device sends telemetry data to AWS IoT Core. And I used AWS IoT Core Rules to read data from topic and send it to my own webservice deployed in some other place. When I am try to add authentication in HTTP Rule, it is showing SigV4 based authentication. What is that and how to use it ? Do I need to any code changes in my webservice ?

Answer 1

After some investigation I cam to know, that sig4 is used to call AWS services, not other webhooks. So I am planning to invoke, Lambda and push the data
