E-commerce Order Fulfillment

​

Introduction

This example demonstrates an automated e-commerce order fulfillment process using Upstash Workflow. The workflow takes an order, verifies the stock, processes the payment, and handles order dispatch and customer notifications.

​

Use Case

Our workflow will:

1. Receive an order request
2. Verify the availability of the items in stock
3. Process the payment
4. Initiate the dispatch of the order
5. Send confirmation and delivery notifications to the customer

Code Breakdown

Key Features

1. Stock Verification: Ensures items are available in stock before processing the payment, avoiding issues with unavailable products.

2. Payment Processing: Handles payment securely and only proceeds to dispatch if successful.

3. Customer Notifications: Keeps the customer informed at each step of the order process, improving user experience.
