Required

• An approved RynoPay partner account -- see Onboarding for how to register and get approved.

• Your API Key ID (UUID) -- created via the Partner Portal after uploading your public key.

Tools

• OpenSSL (or equivalent) for generating your ECDSA key pair.
• A server-side environment -- Node.js, Python, Java, C#, Go, or any language with a JWT library that supports ES256 signing.

  • https://sandbox.rynopay.io -- sandbox environment
