In some post functions you can use tags that will be replaced with the Jira issue values. For example:
Smart value | Content |
|---|---|
{issue.key} | The issue key |
{issue.fields.project.key} | The project key |
{issue.summary} | The issue summary |
{issue.fields.customfield_10061} | The value of the custom field with id 10061 |
The JSON representation of the issue is used to create the smart values for a given issue.
