How this workflow works, step by step

1 Trigger Calendar change

The workflow starts when Google Calendar or Outlook Calendar signals "calendar change". Carly is listening continuously, so the run begins within seconds of the event.
2 Filter Event = busy

Carly drops anything that doesn't match: event = busy. The flow only continues for relevant items.
3 Action Update slots

Carly takes action: update slots. This is the visible outcome of the workflow.

When to use this template

You want this work to happen consistently without anyone remembering to do it.
You're already using Google Calendar and Outlook Calendar, and the manual version of this is eating real minutes a week.
You want a visible canvas you can audit and edit — not a black-box agent doing things you can't see.

When not to use it

This task only happens once or twice a month — the setup cost won't pay back.
The decision in the middle of the flow needs human judgment every single time, not just on edge cases.
Your stack doesn't include any of the apps above and you don't want to wire a generic HTTP step.

Questions teams ask before building this

How long does this workflow take to set up?

Most teams have "Block busy time on your Carly booking page" running in under 10 minutes. Copy the prompt on this page into an email to carly@usecarly.com and Carly wires the workflow together for you, including authenticating Google Calendar.

Can I edit this template after Carly builds it?

Yes. Every workflow lives on the Carly canvas where you can rename steps, change conditions, swap LLM models, add filters, and re-route branches. Templates are starting points, not locked recipes.

What if I use a different tool than the ones in this template?

Carly connects to 200+ tools, plus a generic HTTP node for any API that doesn't have a native integration. Tell Carly your stack when you send the prompt and she'll pick the right connectors.

Does this run automatically once it's built?

Yes. The trigger at the start of the workflow fires automatically — on a schedule, on an inbound email, on a webhook, on a calendar event, whatever this template specifies. Carly handles the listening; you only step in when a step is gated on you.
