get ticket id in jsx

[Lilian Allio]

I'm starting to create an application in Jira(JSX), to help to resolve a ticket, but for that I need the ticket id, but I don't know how to do it. 

For example, i'm in a ticket, i click on a button on the app and i want to get the ticket id where I am.

Hi Lilian - Welcome to the Atlassian Community!

I assume you don't mean the ticket/issue key (like ABC-123) but the actual ID of the issue. If you run a query/filter and then export it to CSV (with default fields) you should see the ID as well as the Key.
