Automate Cascading Field Values in Jira Cloud

Summary

Update cascade custom field options in Jira Cloud using automation.

Solution

Setting a cascading (parent/child) select field via Automation fails with a JSON parsing error unless the payload nests child inside the parent correctly. Two valid syntaxes are below — one by option name, one by option ID.

Syntax 1 with option names:

{ "update": { "customfield_10265": [ { "set": { "value": "Parent 1", "child": { "value": "Child 1" } } } ] } }

Syntax 2 with the option IDs:

{ "update": { "customfield_10265": [ { "set": { "id": "10125", "child": { "id": "10132" } } } ] } }

Get parent/child option IDs from the Issue custom field options REST API. Replace customfield_10265 with your field ID.

To confirm it works, run the rule on a test issue and verify that both the parent and child cascade values are set (check the audit log for a JSON error if not).
