Accept YooKassa payments and log transactions in Google Sheets

🧾 Summary

This workflow allows you to accept online payments via YooKassa and log both orders and transactions in Google Sheets — all without writing a single line of code. It supports full payment flow: product selection, payment initiation, webhook processing, refund updates, and payment status checks.

👥 Who is this for?

This template is ideal for:

• Online stores with simple checkout flows
• Sellers of digital products or info-courses
• Entrepreneurs using Telegram bots or web forms
• Anyone needing quick payment integration with Google Sheets tracking

🎯 What problem does this workflow solve?

Setting up online payments usually requires backend infrastructure. This no-code solution automates the entire payment flow:

• Handles product listing and price retrieval
• Initiates payments with email and return URL
• Listens for payment.succeeded and refund.succeeded events
• Records every action into structured Google Sheets

⚙️ What this workflow does

1. GET /products

Returns a sorted list of products from a Google Sheet (products).

2. POST /payment

• Validates required fields (product_id, email, return_url)
• Checks email format
• Fetches product data from products
• Generates a unique idempotence key
• Sends a request to YooKassa API
• Saves the order into the orders sheet
• Returns a payment confirmation link

3. POST /yoomoney

Webhook to process payment/refund events:

• On payment.succeeded, adds entry to transactions
• On refund.succeeded, updates transaction status

4. GET /status/:id

Returns real-time payment status from YooKassa

🚀 Setup

1. Connect credentials:

   • Google Sheets (OAuth2)
   • YooKassa (Basic Auth using shopId and secretKey)

2. Update the following Google Sheets:

   • products: should contain product_id, title, price
   • orders: for saving confirmed purchases
   • transactions: for logging all successful or refunded payments

3. Test endpoints using any HTTP client:

Example payload for /payment:

{
  "product_id": "abc123",
  "email": "[email protected]",
  "return_url": "https://your.site/success"
}

🔧 How to customize this workflow

• Add delivery logic (e.g., email with product link after successful payment)
• Replace Google Sheets with a database (e.g., PostgreSQL)
• Connect Telegram or other messengers for post-payment notifications
• Add promo codes, discounts, or subscriptions logic

💼 Use cases

• Simple online checkouts
• Telegram bots selling access
• Educational product sales
• MVP e-commerce flows
