Calendly → Slack Workflow Triggering Twice for Each Appointment

Hey everyone,

I’ve got a Pabbly Connect workflow where every time we book an appointment in Calendly, it sends the details to Slack. The problem is, for every single booking, I get two Slack notifications instead of one.

When I tried to fix this by reconnecting the Calendly trigger, I got the following warning:

“Do you wish to resend the request again?
You have already used the event ‘Invitee Created (Organization)’ of ‘Calendly’ for this workflow. If you resend the request, duplicate data for the same event may arrive. This may affect your workflow by making it execute multiple times for the same event.
Do you still want to resend the request again?”

I’m assuming this is what’s causing the duplicates, but I’m not sure how to properly fix it without breaking the workflow.

Here’s the workflow link for reference:

Any idea how to stop this from triggering twice per appointment?

Thanks in advance!

Hi @oscarbnihrane,

The issue you are describing occurs when a user clicks on 'Save & Send Test Request' multiple times. This, in turn, creates multiple webhooks in Calendly, leading to the workflow being executed multiple times.

To fix this issue, you need to disable your current workflow, clone it, and set up the Calendly trigger step in the new workflow. Make sure to click the 'Save & Send Test Request' button only once while setting up the trigger step.
