Because you are working with sensitive financial data, we ensure that our Nuapay API is highly secure.

We use API Keys to ensure the security of your sensitive data, which is transmitted via Secure Sockets Layer (SSL) over the HTTPS protocol.

For certain endpoints you must provide a JOSE Header in your requests. To do this you will need to create a private key and certificate and use these to generate the JOSE Header. See JSON Web Signature for more on this.
