RESTful API

Our RESTful API allows you to programmatically initiate USDT transfers, check transaction status, manage wallets, and more. The API is designed to be simple, intuitive, and powerful.

Authentication

All API requests require authentication using API keys. You can generate API keys in your Flash USDT developer dashboard.

// Example API request with authentication
curl -X POST \
  https://api.flashusdt.com/v1/transfers \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{
    "amount": "100.00",
    "from_wallet": "YOUR_WALLET_ID",
    "to_address": "RECIPIENT_USDT_ADDRESS",
    "network": "trc20",
    "memo": "Payment for services"
  }'

Rate Limits

API requests are subject to rate limiting to ensure fair usage and system stability. Rate limits vary based on your API plan.

Real-Time Notifications

Webhooks allow your application to receive real-time notifications about events that occur in your Flash USDT account, such as completed transfers, failed transactions, and more.

Setting Up Webhooks

To set up webhooks, you'll need to provide a URL where Flash USDT can send HTTP POST requests when events occur. You can configure webhooks in your developer dashboard.

// Example webhook payload for a completed transfer
{
  "event": "transfer.completed",
  "created_at": "2025-04-02T10:15:30Z",
  "data": {
    "id": "tr_123456789",
    "amount": "100.00",
    "from_wallet": "wlt_abcdefg",
    "to_address": "TRx1234567890abcdefghijklmnopqrstuvwxyz",
    "network": "trc20",
    "status": "completed",
    "transaction_hash": "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef",
    "completed_at": "2025-04-02T10:15:25Z",
    "fee": "0.01"
