What is ECA in Drupal — And Why You Should Know It

If you've been building Drupal sites, you've probably written custom modules just to send an automated email or build a simple approval flow.
What if you didn't have to?
That's what ECA is for.

ECA = Events, Conditions, Actions
It's a Drupal module that lets you build automated workflows from the admin panel — no custom PHP needed.
The mental model is simple:

When this happens → check this → do this

Real example:

Event: User submits a form
Condition: User role is "Student"
Action: Send a welcome email + assign them to a group

Zero code. Built visually in minutes.

Why Developers Love It

Visual interface — flowchart style, easy to debug and explain to clients
Covers most use cases — form submissions, entity changes, user login, scheduled triggers
Works with popular modules — Webform, Views, Token, Rules
Exportable — save workflows as config, reuse across projects

Quick Install

composer require drupal/eca drupal/bpmn_io
drush en eca eca_base eca_content eca_user eca_form eca_ui bpmn_io
drush cr

Then go to Configuration → ECA and you'll see the visual workflow builder.

Bottom Line
ECA replaces hours of custom module development with a visual, maintainable workflow anyone on your team can understand.
In the next post I'll walk through building a real automated email reminder with ECA — step by step.
Follow so you don't miss it.

Have a workflow you're currently solving with custom code? Drop it in the comments — might be the next tutorial.
