The four kinds
One automation can use several
Triggers stack. You do not pick one and give up the rest. The same automation can run every night at nine, run again when a webhook fires, and run once more when you press the button. All three paths hit the same code. The trigger only decides when the work starts, never what the work does. This helps more than it sounds like it would. You can always press the button to watch your automation run while you build it. And when you add a schedule three weeks later, you do not rebuild anything.Your workspace sleeps, and that is fine
Your workspace pauses when nothing is happening. That is why you can leave a dozen automations sitting around without paying for idle time. It also means a timer running inside the machine would die with it. So the platform keeps the clock for you and owns the public URLs. When your schedule ticks, when someone calls your webhook, or when mail arrives, the platform wakes your workspace and hands over the event. You lose nothing while it sleeps.Waking takes a few seconds. A trigger can land 10 to 60 seconds after the event
that caused it. That is normal. Do not build anything that needs to fire at an
exact second.
