Connecting to a payment gateway rarely fails because of business logic. More often, it fails at the very first technical step: authentication.
If you’ve ever worked with payment APIs, you know the drill. Before sending a single request, you need to generate a cryptographic key pair and sign every request correctly. Sounds straightforward—until you actually try to do it.
The hidden hurdle in every integration
To securely call the Payneteasy API, each request must be signed. That means:
Generating an RSA key pair (usually via OpenSSL)
