How Can We Help?

Getting started is easy! First, sign up for an account and get your API keys. Then install our SDK using `npm install paykly` and follow our quick start guide. You can be accepting payments in less than 30 minutes.

We currently support KOLAY, BNB, USDT, and BUSD on the Binance Smart Chain. We're constantly adding support for more currencies based on merchant demand.

Yes, PayKLY uses bank-grade security. All transactions are verified on the blockchain, and we use signature verification to ensure transaction authenticity. We never store private keys and follow industry best practices.

Yes, you can process refunds through our API or dashboard. We support both full and partial refunds. Refunds are processed on the blockchain and typically complete within a few minutes.

Yes! We provide a complete testnet environment where you can test all features without using real funds. Just set `network: 'testnet'` in your SDK configuration.

If a payment fails, you'll receive a webhook notification with the error details. Common reasons include insufficient funds or network congestion. The payment will remain in a 'failed' state and won't be charged.

Webhooks allow you to receive real-time notifications about payment events. You provide a URL where we'll send POST requests with event data. Each request includes a signature for verification. Check our documentation for complete setup instructions.
