How to Accept USDT Payments on a Website, WooCommerce or API

Last updated: 2 November 2026

If you want to accept USDT payment on a website, you need three things: a way to show customers the right amount, coin and network; a way to match each incoming transfer to an order; and a plan for what happens to the money afterwards. A USDT payment gateway packages those steps so you do not have to run your own blockchain nodes. This guide walks through the choices (hosted payment page, WooCommerce or other plugin, API), a step-by-step setup, a webhook example, the failure cases to test and a calculator for net receipts. It is aimed at merchants registered outside mainland China. For the security side, our Chinese SOP on USDT receiving security covers address poisoning and wrong-chain transfers, and the 7-step launch checklist is in Chinese.

Compliance note: the PandaWM crypto payment gateway is operated by a Hong Kong company and serves merchants registered outside mainland China and their overseas customers only; it is not offered to mainland China residents. PandaWM holds an MSB (Money Services Business) license. Merchants remain responsible for the laws of the places where they operate and sell, and must expect identity (KYC), anti-money-laundering and sanctions checks. See our crypto payment compliance guide (Chinese). This article is general information, not legal, tax or investment advice.

USDT as a payment method: what you are accepting

USDT is a stablecoin issued by Tether. The same token exists on several blockchains, and each network has its own address format, fees and wallet support. Tether lists the protocols it supports on its Supported Protocols page. A transfer sent on the wrong network may not be recoverable, so your checkout must state the network clearly and your gateway should generate a payment request tied to one network per order. As a USDT payment method, it behaves like a push payment: the customer sends funds; you cannot “pull” a recurring charge the way you can with a saved card.

Choose your integration route

Route	Best for	Effort	Notes
Hosted payment page or payment link	Agencies, invoices, small shops with no developer	Low	Create a link per invoice; customer pays on a hosted page
E-commerce plugin (for example WooCommerce)	Stores on a supported platform	Low to medium	Install, enter keys, set callback URL, test
API or SDK	Custom websites, SaaS, games	Medium to high	Full control; you build order matching and webhooks
Self-hosted wallet	Technical teams who want to hold keys	High	You own security, monitoring and accounting

PandaWM offers API, open-source wallet and e-commerce plugins, and SDKs. We confirm the exact plugin list, supported coins and networks, and API fields during onboarding. See also WooCommerce crypto payment plugin (Chinese), Shopify (Chinese) and USDT for online stores (Chinese).

Step-by-step: add USDT to a WooCommerce store

Apply and verify. Open a merchant account with your gateway and complete KYC. Turn on 2FA and give each person their own login.
Decide your settlement. Keep USDT, or convert and withdraw to a bank where available. Confirm payout countries and fees.
Install the plugin. Use the plugin supplied by your provider, from the provider’s official site or the WordPress plugin directory. Check the developer name and update date before installing.
Enter credentials. Paste the API key or merchant ID into the plugin settings. Store keys only in the plugin; never in public code or screenshots.
Set the callback (webhook) URL. Copy the URL shown by the plugin into your gateway dashboard so order status updates reach WooCommerce.
Map order statuses. Decide which gateway status (pending, confirmed, underpaid, expired) maps to which WooCommerce status (on hold, processing, failed).
Write the checkout text. State the coin, the network and what happens if the customer pays the wrong amount.
Test with small amounts. Run a successful payment, an underpayment, an overpayment, a late payment and a wrong-network attempt if your provider supports a test mode. Check that each case lands in the right status.
Go live and reconcile weekly. Export transactions and match them to orders and your bank or wallet statements.

USDT checkout flow from order to settlement

API route: what your developer needs to build

Create a payment request per order (amount, currency, network, your order ID).
Show the customer the address or QR code, the exact amount and a deadline.
Receive webhooks and verify their signature before trusting them.
Make handlers idempotent: the same event may arrive twice.
Query status as a fallback if a webhook is missed.

An illustrative signature check is below. Field names, header names and algorithms differ by provider, so always follow your provider’s documentation.

// Illustrative only - follow your provider's docs
const expected = hmacSHA256(secret, rawBody);
if (!timingSafeEqual(expected, headers["x-signature"])) return 401;
const evt = JSON.parse(rawBody);
if (alreadyProcessed(evt.id)) return 200;   // idempotency
if (evt.status === "confirmed" && evt.amount >= order.amount) markPaid(order.id);
else if (evt.status === "underpaid") flagForReview(order.id);
return 200;

Net-receipt calculator

The default gateway fee below is PandaWM’s 1% per transaction. Network, withdrawal and bank fees depend on your setup, so the defaults are zero placeholders: fill in your real numbers. The result excludes exchange-rate spread and taxes.

Order amount (USDT) Gateway fee (%)

Network fee you pay (USDT) Withdrawal or bank fee (USD)

Failure cases to decide before launch

Case	What to decide	Customer message
Underpayment	Top-up request, partial refund or cancel	“We received X; please send the remaining Y within 24 hours.”
Overpayment	Refund the difference or credit the account	“You paid more than the order total; reply to receive a refund.”
Late payment after expiry	Re-quote the price or refund	“Your payment window expired; contact us with the transaction hash.”
Wrong network	Recovery is often impossible; check whether your provider offers a manual process	Warn clearly at checkout to prevent it
Duplicate payment	Refund one transfer	“We received two payments for one order.”

Crypto refunds are new transfers you send; see refunds and reconciliation (Chinese). Decide who covers the network fee and say so in your terms.
