# Workflows

> Automate processes by connecting agents, tools, and external services into repeatable workflows.

Workflows let you automate multi-step processes inside your EK project. You define a trigger — the event that starts the workflow — and then chain together agents, tools, conditions, and outputs into a sequence that runs automatically.

EK has two workflow builders. V1 is the original implementation, still fully supported. V2 is the current builder, with a broader set of triggers, a visual drag-and-drop canvas, execution debugging, and version history. New workflows should be built in V2.

<Warning>
  Workflow Builder V1 is deprecated and will be removed on **September 7, 2026**. A migration tool is available in the V1 interface to move existing workflows to V2. See the [V1 Deprecation Notice](/changelogs/feature-deprecations/workflows-v1-deprecation) for the full timeline and migration guidance.
</Warning>
