captured through a webhook and cleaned to keep only important details like event ID, user ID, RSVP status and time.**\n\n**Attendee information is saved in Airtable using upsert logic, which prevents duplicate records and keeps RSVP status up to date.**\n\n**The workflow then counts how many people are marked as attending for the event.**\n\n**This count is compared against the event\u2019s maximum capacity.**\n\n**If the capacity is reached or exceeded, the workflow checks whether the team has already been notified.**\n\n**If no alert was sent earlier, a Slack message is sent to inform the team that the event is full.**\n\n**Finally, Airtable is updated to record that the capacity alert has been sent, preventing duplicate notifications.**\n\n## Setup Steps\n\n**Create a webhook to receive Facebook RSVP events.**\n\n**Normalize the incoming data using a Set node.**\n\n**Store or update attendee records in Airtable.**\n\n**Count confirmed attendees and compare with event capacity.**\n\n**Send a Slack alert when capacity is reached and mark it as sent.**" }, "typeVersion": 1 } ], "active": false, "settings": { "executionOrder": "v1" }, "versionId":
