2.How to connect our POS application with RestFull API?
3.Do we need to have any SDK to connect with RestFull API?Do we need to install any app (on Clover mini device or in our machine) for integration to work with CLover Mini Device(USB Pay Display App or Secure Network Pay Display App)?
4.Could you please send the link with examples to work with ReSTfull API?
The Clover Web API is accessible as long as you can make HTTP requests. However, to take payments remotely through a Clover device, you will need to use one of the Remote Pay SDKs. The Clover Web API does not provide an interface for initiating payments on a Clover device.
Here are the links to the Web API resources in case you still want to take a look. Unfortunately there's not an example application I can point you to.
