I want to add webhook to issues in jira using API but parent clause is not supported

[Username]

In below code parent clause in jql_filter is not supported even though it works in jira account when i try to add webhook manually, why?

    @staticmethod

    def add_issue_webhook(project_key, issue_key):

        user_id = session.get('user_id')

        if not user_id:

            return ('Not authenticated'), 401

        user_token = UserToken.query.filter_by(user_id=user_id).first()

        if not user_token:

            return ('No tokens found for the authenticated user'), 400

        access_token = user_token.access_token

        headers = {

            'Authorization': f'Bearer {access_token}',

Welcome to the community, @Username 

I see some conflicting API references online. You might try something like this example and see if it's better:

{
  "name": "my first webhook via rest",
  "description": "description of my first webhook",
  "url": "https://www.example.com/webhooks",
  "events": [
    "jira:issue_created",
    "jira:issue_updated"
  ],
  "filters": {
    "issue-related-events-section": "Project = JRA AND resolution = Fixed"
  },
  "excludeBody" : false,
  "secret" : "G8j4166a5OkXRD4WbqV3"
}

Note the "filters" dictionary instead of the "jqlFilter" string. Both forms are referenced in the documentation.

actually I am using OAuth2.0 app and for that, i need jql_filter else it shows error [{'errors': ['Empty JQL search not supported']}]},

I am trying to add webhook to specific issue inside project then whenever child issue is created in that issue i want that event to trigger webhook and currently i am using 

jql_filter = f'project = "{project_key}" AND issuekey = "{issue_key}"'

but in this webhook is triggered when selected issue is updated but doesnt when any child issue is created, is there a way to get triggers when child issue are created too
