This page describes how to customize your workflow for conditions and validators.

Writing Conditions and Validators

Conditions and validators are important components in workflow customization. They have no side effects and are written in the Jira Expressions language, a subset of Javascript created by Atlassian.

Runtime User & Issue

Conditions and validators execute when the user activates a transition, and the issue is in scope.

Return Codes

Expressions must return a boolean statement, signaling the condition or validator passed the system check.

Validator Message

The validator message is static. It can be defined but not dynamically formatted.
