📦 Use Case
Example Product: AI-Powered Social Media Content Generator & Publisher
When a customer buys this product through PayPal, this automation:

Listens for a successful payment event
Fetches order details via API
Sends an HTML email with the template attached
Promotes your other offerings with embedded links

🔧 Prerequisites
You’ll need:
An n8n instance (self-hosted or n8n Cloud)
A PayPal developer account
PayPal OAuth2 credentials configured in n8n
Your product hosted as a downloadable .json file (Oracle, Dropbox, GitHub, etc.)
SMTP email credentials in n8n

🧠 Step-by-Step Setup

1. Webhook Trigger
   Node: Webhook
   Listens for a POST request from PayPal’s webhook for PAYMENT.CAPTURE.COMPLETED events.
   📌 Add the webhook to your PayPal Developer App > Webhooks.

2. Wait
   Node: Wait
   Adds a brief delay to ensure the payment is completely processed before continuing.

3. Filter Event Type
   Node: Switch
   Processes only when the event is PAYMENT.CAPTURE.COMPLETED.

4. Fetch Order Details
   Node: HTTP Request
   Retrieves the order information from PayPal's Orders API.
   URL format:
   https://api.paypal.com/v2/checkout/orders/{{ order_id }}

5. Extract Email & Product Info
   Node: Set
   Extracts first name, last name, email address, and the purchased item name.

6. Identify Product Purchased
   Node: Switch
   Checks if the product is “AI-Powered Social Media Content Generator & Publisher”.

7. Download Workflow File
   Node: HTTP Request
   Fetches the hosted workflow JSON from object storage (Oracle in this case).

8. Convert to Downloadable File
   Node: Code
   Converts the JSON content into a binary file and attaches it.

9. Send Custom Email
   Node: Send Email
   Sends a rich HTML email to the buyer with:
   Their name
   The file attachment
   Product name
