Automate Payment Confirmation & Abandoned Registration Follow‑Up (Google Sheets + WhatsApp)

Introduction

Turn event sign‑ups into confirmed attendees by instantly checking payment status, saving details, and sending the right WhatsApp message at the right time ✅

Trigger Event

A new registration hits your webhook from a checkout page or form.

Actions

• The workflow checks if the registration is for the targeted course and whether payment was completed.

• If payment is PAID:

  • Save the attendee’s name, email, phone, amount, currency, order ID, and course details in Google Sheets with a PAID status and timestamp.
  • Send a WhatsApp welcome message with event date/time and a helpful link.
  • Create/update the contact in your messaging CRM and add them to the right group for future updates.
  • Send a lightweight notification to your internal system for tracking.

• If payment is NOT completed (abandoned):

  • Save the lead in Google Sheets with an Abandoned status and timestamp for follow‑up.
  • Send a WhatsApp nudge with course info and a link to complete registration.

Outcome: every registrant is captured, confirmed attendees get details immediately, and abandoned sign‑ups receive timely prompts to convert.
