Sync Stripe payments to GoHighLevel with GPT-4o email, Slack, and Sheets logging

Description

Who It's For
Agencies, service businesses, and GoHighLevel users who want to automatically update their CRM, notify their team, and send a professional invoice to the customer the moment a Stripe payment lands.

How It Works
Webhook receives the Stripe payment event
Configure Variables node sets your Slack channel, GHL pipeline stage ID, and Google Sheet ID in one place
OpenAI writes a professional invoice summary email based on the customer name, payment amount, and product purchased
Gmail sends the invoice summary to the customer
HTTP Request node calls the GoHighLevel API and moves the contact to the paying client pipeline stage
Slack notifies your team with the customer name, payment amount, and updated pipeline stage
Google Sheets logs the customer name, email, amount, product, and timestamp for bookkeeping

Set Up Steps
Update the Configure Variables node with your Slack channel name, GHL pipeline stage ID, and Google Sheet ID
Set up an HTTP Header Auth credential in n8n with your GoHighLevel API key and connect it to the Update GoHighLevel Contact node
Connect your Gmail, OpenAI, Slack, and Google Sheets credentials to each node
Point your Stripe webhook to the webhook URL generated by the Stripe Payment Webhook node
Activate the workflow

Stripe account with webhook configured
OpenAI API key
Gmail account with OAuth credential
