API

You will need your GreenPay secret, merchant, terminal and publicKey in order to use this library.

greenpay(options)

Create a new instance of greenpay api by passing the required secret, merchant, terminal and publicKey properties.

const api = greenpay({
    secret: '<GREENPAY_SECRET>',
    merchant: '<GREENPAY_MERCHANT>',
    terminal: '<GREENPAY_TERMINAL'>,
    publicKey: '<GREENPAY_PUBLIC_KEY>'
})

You can also set the GREENPAY_SECRET, GREENPAY_MERCHANT, GREENPAY_TERMINAL and GREENPAY_PUBLIC_KEY environment variables instead of passing properties directly.

For example, lets say somewhere in your app you have:

const api = greenpay()

You can startup your node application like this:

GREENPAY_SECRET=abc123 GREENPAY_MERCHANT=my-merchant GREENPAY_TERMINAL=my-termianl GREENPAY_PUBLIC_KEY=my-public-key node app.js
