I can't get events for webhook

[Daniel Bedoya]

Hello everyone.

I'm trying to set up a webhook via API to receive events from my project. This is the curl request I'm attempting:

curl --location 'https://api.atlassian.com/ex/jira/cloud_id/rest/api/3/webhook' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer bearer_token' \
--data '{"url": "https://webhook.site/5975cd73-75db-433c-aaf0-283782da5928", "webhooks": [{"events": ["jira:issue_created", "jira:issue_updated", "jira:issue_deleted", "comment_created"], "fieldIdsFilter": null, "jqlFilter": "project != null"}]}'

But I'm not receiving any events at the specified URL. Does anyone know what I might be doing wrong?
