Use cases
Built for payment operations and developers
When a customer says they paid, an order remains pending, or a webhook reached your endpoint but the application did not update, these tools turn the investigation into verifiable facts.
Order remains pending
Check network, token contract, exact amount, destination address, expiration window, and confirmation depth.
Webhook did not update the app
Use the webhook tester to reproduce the callback, signature headers, and raw body your endpoint expects.
Retry behavior needs validation
Confirm your endpoint returns non-2xx only for retryable failures and 2xx after the business state has been durably processed.
FAQ
Payment tool questions
Choose the right diagnostic path with fewer steps and avoid trial-and-error on production orders.
Which tool should I use for a pending USDT order?
Use the USDT Transaction Checker first. It helps compare the transaction hash, selected network, destination address, transfer amount, order status, and confirmation count.
Which tool should I use for callback failures?
Use the Webhook Tester when the payment is complete but your application did not update, or when signature verification fails.
Do these tools modify production orders?
No. The public tools are diagnostic helpers. They do not mark orders as paid, send customer notifications, or trigger production webhooks.
