Clockwork Customization Example: Send Email When Worklog Created
This automation rule checks for manually-created worklogs and sends an email to notify manager/designated user.
Navigate to Project Settings > Automation.
Click Create Rule > Create rule from scratch.
Select Work Logged as the trigger.
Click Next.
Select the Send Web Request action.
Web Request URLs - Remember to correct your Jira URLs https://your_jira_url.atlassian.net/rest/api/3/issue/{{triggerissue.key}}/worklog/{{worklog.id}}?expand=properties
HTTP method - GET

Add a header. Here you need to create the API token. It can be done on this Jira page. Next, you need to encode it in Base64. You can use this page to do that. The value to encode should have the format: your@email.adress:API_Token
Key - Authorization
Value - In value please put “Basic encoded_Base64_token” (without quoting)
Add {{smart values}} condition:
First value: {{webResponse.body}}
contains
Second value: tracking_mode=manual
Add Action: Send Email
