APIs play an important role in Crypto Payment Gateway Development because they connect the gateway with merchants, wallets, and blockchain networks.

Here’s how APIs are typically integrated:

Connect to blockchain nodes (like Bitcoin or Ethereum) to create wallets, generate addresses, and track transactions.

Provide simple REST APIs so websites and apps can accept crypto payments, create invoices, and confirm transactions.

Manage deposits, withdrawals, and balance checks securely.

Fetch real-time crypto-to-fiat conversion rates.

Integrate KYC, AML, and fraud detection services.

All APIs are secured using encryption, authentication keys, and token-based access to maintain strong security and easy transaction processing.
