Workflow

• A user wants to sign up for a workshop/event
• Once registered, he needs to pay his ticket and is then approved for the workshop
• A confirmation mail is sent with details

Implementation

We "simulate" the payment gateway here, of course

• We have synchronous triggers (user on site sends registration form)
• There are also async triggers, e.g. status update from payment provider
• We also trigger async events and queue jobs, e.g. for sending emails

Let's try it

Register for the event

A real life example can often be 10-20x larger in complexity.
