Hey @krishna7,

At the moment, these are the supported field type:

- DATE, NUMBER, SELECT, TEXT, TEXTAREA, OWNER

Having said that, our team is working on a new version of the [Automation API | Custom Workflow Actions](https://developers.hubspot.com/docs/api/automation/custom-workflow-actions) and I’d be happy to check in with the internal team to see if radio selection will be part of the new feature. I’ll keep you posted with update here!
