How to call external application REST API from Jira

[Nakul]

Would like to understand how to get issue (story) details from Jira in to an external application? 

Can we call the external application REST API from Jira using web hooks?

here is my use case:

1. Identified issues from Jira shall get transferd into an external application.

2. Any updates in Jira for the issues shall be updated into the external application.

The external application provides create and update REST API and we want to call them from Jira

Hi @Nakul 

Yes, you can use webhooks to communicate with external application. When triggered a webhook send POST request to your application with JSON included (if configured) with information about the issue. But your application has to be able to serve that requests, parse JSON and perform all necessary action (create\update from source info). Here is more info about webhooks:
