We provided WebHook variables so that users can include some information on the URL. However some of them is not working although documented.

• https://developer.atlassian.com/jiradev/jira-apis/webhooks#Webhooks-VariablesubstitutioninthewebhookURL

Variable mentioned on the documentation

${board.id} 
${issue.id} 
${issue.key} 
${mergedVersion.id} 
${modifiedUser.key} 
${modifiedUser.name} 
${project.id} 
${project.key} 
${sprint.id} 
${version.id}

Variable showing when creating a new WebHook

${attachment.id}
${board.id}
${comment.id}
${issue.id}
${issue.key}
${mergedVersion.id}
${modifiedUser.key}
${modifiedUser.name}
${project.id}
${project.key}
${sprint.id}
${version.id}
${worklog.id}

So far the tested working is only on the variable below:

${issue.id}
${issue.key}
${project.id}
${project.key}

Steps to replicate

1. Create a webhook and assigned one of the variables listed, eg attachment.id
   • https://requestb.in/123456?id=${attachment.id}
2. Create a request bin
3. Fire an event that triggers the webhook configured above

Expected Result

Returning the attachment id on the ticket that triggers the event.

Actual Result

Empty Result returned

Workaround

There are no workaround for this, however, the changes will be capture in the body if the event is of the same type. Eg, attaching an issue will fire an update event and carries the information on the body of the request.
