What is API Versioning?
API Versioning explained for crypto payment merchants using Zateway.
API Versioning is a key concept in crypto payments. With Zateway, merchants use non-custodial USDT and USDC checkout across Polygon, Solana, Base, BSC, Arbitrum, Optimism so API Versioning connects directly to faster settlement, lower fees, and zero chargebacks.
Why API Versioning Matters for Merchants
Understanding API Versioning helps you design safer checkout. Zateway keeps funds non-custodial — payments route to your wallet while you still get webhooks, payment links, and API control.
How Zateway Handles API Versioning
Zateway supports production and sandbox flows so you can test API Versioning safely. Use payment sessions, HMAC webhooks, and multi-chain USDT/USDC to operationalize this concept without holding customer funds.
Best Practices
Prefer stablecoins over volatile assets, verify webhook signatures, wait for sufficient confirmations, and keep private keys offline. Pair API Versioning knowledge with Zateway's 1% flat fee model for predictable unit economics.
