Workflow concepts [workflows-concepts]

Concept and reference material for the components that make up a workflow definition. Use this section when you need to know what a specific trigger or step accepts, what its output looks like, or how templating expressions are evaluated.

• Triggers: Manual, scheduled, alert, and event-driven triggers.
• Steps: Action, flow control, AI, data, and composition steps.
• Templating engine: Liquid templating syntax and custom filters.
• Reference: Quick-reference pages for the workflow YAML surface. Cheat sheet, A-Z step type index, context variables, and the Liquid filter catalog.
• Authorization: Whose privileges authorize a workflow run and what the run's API key can access.
