## Example

- With Redirect Urls

```
    import { PayfastHandler } from 'payfastjs-helper'

    const paymentHandler = new PayfastPayment('123', 'abc', 'mypassphrase);

    // create payment
    await paymentHandler.createPayment({
    	amount: '100.00',
    	email_address: 'example@example.com',
    	item_name: 'my demo product',
	    cancel_url: 'https://demo.demo/cancel_payment',
	    return_url: 'https://demo.demo/return_payment',
	    notify_url: 'https://demo.demo/post_to_notify_url'
    }, {sandbox: false, onsite: true})
```

Method will redirect you to your cancel_url / return_url

- With Callback

```
    import {PayfastHandler} from 'payfastjs-helper'

    const paymentHandler = new PayfastHandler('123', 'abc', 'mypassphrase);

    // create payment
    await paymentHandler.createPayment({
    	amount: '100.00',
    	email_address: 'example@example.com',
    	item_name: 'my demo product',
	    notify_url: 'https://demo.demo/post_to_notify_url'
    }, {onsite: true} ,(success) => {
		if (success){
			// payment successful
		}else{
			// payment cancelled or failed
		}
	})
```

- Method will not redirect you to your cancel_url / return_url, but rather return callback if both 'cancel_url' and 'return_url' is empty.

## Roadmap

- Tokenization
- Split payments
- Better error handeling
- Class to handle Server Side validations and methods
