API Activity in community edition

I am unable to create a bot for API activity in community edition.
Version : 17.5.5

Hi Rahul,

Please share the steps you are performing to call an API activity.

I created an app first for REST api, and i gave endpoint url as follows:
endpoint url : http://dummy.url/

To run an API i selected this app and gave the name of API e.g.
if API is http://dummy.url/abc
i gave the name as “abc” ,
and i configured one out parameter also to capture the result.
