What is OpenAPI Codegen?
OpenAPI Codegen explained for crypto payment merchants using Zateway.
OpenAPI Codegen 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 OpenAPI Codegen connects directly to faster settlement, lower fees, and zero chargebacks.
Why OpenAPI Codegen Matters for Merchants
Understanding OpenAPI Codegen 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 OpenAPI Codegen
Zateway supports production and sandbox flows so you can test OpenAPI Codegen 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 OpenAPI Codegen knowledge with Zateway's 1% flat fee model for predictable unit economics.
