To sign Binance Onchain Pay API requests, you must generate an RSA SHA256 signature using a provided PEM key over the compact JSON request body and cross-platform millisecond timestamp, then include the signature in the required Tesla headers.

Creating a fiat-to-crypto pre-order link requires providing externalOrderId, merchantCode, merchantName, timestamp, network, address, and payMethodCode in the request body to generate a redirect link for completing the payment.

Yes, integrating Binance Onchain Pay API payment flows requires Python3 and OpenSSL to handle the RSA SHA256 request signing and send POST requests with the necessary Tesla headers to the configured base URL.

Yes, you can monitor order status and discover supported crypto networks by calling the respective Binance Onchain Pay Open API endpoints with properly signed payloads and required parameters.

Yes, the Binance Onchain Pay API supports smart-contract-assisted send primary flows through customization flags and destination contract parameters for specific supported scenarios.

Binance Onchain Pay API calls fail validation if the compact JSON request body lacks required parameters, uses incorrect millisecond timestamps, or misses the RSA SHA256 signature and required Tesla headers in the POST request.
