JIRA webhook is sending only user_id and user_key in post request

Hi all, I am new to JIRA webhook and want to capture all events.  As per link below

https://developer.atlassian.com/server/jira/platform/webhooks/ , I have registered my url here.But when I change in any issue, webhook fires the event but it is sending user_id and user_key in post request . I am unable to see event information. Can any one tell me where the problem is?

maybe check if you exclude the json body
