Calendly to GHL: Trigger Specific Workflows by Event

Question from Reddit user:

Is there a way to connect specific calendly events to ghl events so that certain workflows are triggered?

I use zapier, is that necessary?

I don’t use the ghl calendars simply for aesthetic reasons.

My current situation is using calendly to zapier to lead connector but the leads are getting updated to have the same tag for different events, even when I list in the zap to tag that event accordingly.

I also have the calendar for the sub account linked to my google calendar that’s synced with my calendly.

The short answer is:

How can I connect specific Calendly events to GoHighLevel events to trigger workflows?

Yes, you absolutely can and should connect specific Calendly events to distinct GoHighLevel (GHL) workflows, and the issue you are facing with Zapier applying the wrong tags is a very common limitation when relying on a single Zap that handles multiple Calendly event types.

While Zapier isn’t strictly necessary, it is the simplest method, and your current problem likely stems from either your Zap’s logic not properly reading the unique event name or slug from Calendly’s data payload, or from a failure to create a separate Zap or a multi-step path/filter within one Zap for each Calendly event type.

The definitive solution for granular control, especially if you have many Calendly event types, is to use the Calendly API and the HighLevel API to build a direct, custom webhook and scripting pipeline that ensures a unique identifier from Calendly is always mapped to a specific action, like tagging or a workflow trigger, in GHL.

The long answer is:

Your current setup, while functional, is demonstrating the tagging fragility of relying on a single, generalized Zapier connection for different Calendly events.

When a booking occurs, Calendly sends a payload of data to Zapier.

That payload contains a specific field that identifies the scheduled event, usually the event name or event slug.

To ensure the correct tag is applied in GHL, your Zap needs to have a filter or a path for each specific Calendly event.

For instance, you should have a Zapier Path A that says “If Calendly event name is ‘Discovery Call,’ then apply tag ‘Discovery Call Scheduled’ in GHL” and a Zapier Path B that says “If Calendly event name is ‘Onboarding Session,’ then apply tag ‘Onboarding Scheduled’ in GHL.” If your current Zap isn’t using these conditional paths, it’s just defaulting to a single action and applying the same tag every time, regardless of the event.

To move beyond this manual Zapier setup and achieve true, reliable separation, the best long-term solution is an API-based architecture.

This involves using the Calendly DataLayer or API and the HighLevel API together.

You would set up a webhook in Calendly to fire to a custom endpoint hosted on a server-side platform like Stape or Google Cloud Platform.

This custom script receives the Calendly webhook data, which explicitly includes the unique event URI, time, and attendee information.

The script then uses the HighLevel API to create or update the contact and, crucially, programmatically assign the correct tag or execute a specific workflow using the Add/Update Contact endpoint with a workflow ID based on the Calendly event URI.

You can even use Google Tag Manager to push custom data to this server endpoint when the booking confirmation page loads.

This direct API pipeline bypasses Zapier’s intermediate logic, guarantees data integrity, ensures your tags are unique to the event, and is highly scalable, making it the superior way to trigger the correct GHL workflows every single time.
