How to Accept USDC Payments in Node.js Using Web3indo (Stripe-Style Crypto Checkout)
Accepting crypto payments in backend applications is still harder than it should be.
If you try to build it yourself, you usually need to:
– generate deposit wallets
– monitor blockchain transfers
– confirm ERC-20 events
– manage RPC reliability
– send webhook notifications
– sweep funds safely to treasury wallets
This quickly turns into infrastructure work instead of product work.
So I built Web3indo — a crypto payment infrastructure API designed for developers.
This article shows how to accept USDC payments in a Node.js backend using a Stripe-style workflow.
What Web3indo does
Web3indo provides:
– per-invoice deposit addresses
– automatic ERC-20 payment detection
– signed webhook delivery
– automatic treasury sweep
– project-scoped API keys
Currently supported:
Ethereum (ETH)
USDC
USDT
Step 1 — Create an API key
After creating a project inside the dashboard:
generate a project-scoped API key.
Each project gets its own isolated API credentials.
Step 2 — Create an invoice
Example Node.js request:
import fetch from "node-fetch";
const response = await fetch("https://api.web3indo.com/v1/invoices", {
method: "POST",
headers: {
"Content-Type": "application/json",
"x-api-key": "YOUR_API_KEY"
},
body: JSON.stringify({
chain: "sepolia",
token: "USDC",
amount: "0.01"
})
});
const data = await response.json();
console.log(data);
Response includes:
– invoice ID
– deposit address
– payment status
– block tracking info
Step 3 — Wait for blockchain confirmation
Web3indo monitors ERC-20 transfer events automatically.
Invoice status transitions:
pending → paid
Step 4 — Receive webhook notification
Example webhook payload:
{
"type": "invoice.paid",
"invoiceId": "abc123",
"chain": "sepolia",
"token": "USDC",
"amount": "0.01"
}
This allows your backend to react instantly:
unlock features
activate subscription
confirm order
Step 5 — Automatic treasury sweep
After payment confirmation:
funds are automatically transferred to your treasury wallet.
No manual wallet management required.
Supported workflow
Typical integration looks like:
create project
generate API key
create invoice
wait for payment
receive webhook
funds swept automatically
Example use cases
Web3indo works well for:
SaaS subscriptions
digital product checkout
developer tools billing
API usage payments
automation platforms
Why I built Web3indo
Most crypto payment integrations today still require managing wallets manually or running custom blockchain listeners.
Web3indo abstracts that complexity into a simple developer API.

Feedback welcome
I’m actively improving Web3indo and would love feedback from other developers building crypto-enabled products.
