              </script>
    </form>

2. Add this snippet in the callback URL

For Python (flask):

    @frontend.route('/callback', methods=['POST'])
    def charge():
        token = request.form['token']
        amount = 100 # in cents
        currency = "USD"
        secret_key = 'secret_key'
        website = 'https://www.example.com'
    
        payload = {'key': secret_key,
                   'website': website,
                   'token': token,
                   'amount': amount,
                   'currency': currency,
                   'description': 'Your transaction description'}
    
        r = requests.post("https://www.checkbook.io/api/v1/charge", data=payload)
        #r = requests.post("https://sandbox.checkbook.io/api/v1/charge", data=payload)

For Nodejs (express):

    var request = require('request');
    app.use(express.bodyParser());
    
    app.post('/callback', function(request, response){
    	token = request.body.token;
    	amount = 100; //in cents
    	currency = "USD";
    	secret_key = 'secret_key';
    	website = 'https://www.example.com';
    
    	payload = {'key': secret_key,
    		   'website': website,
    		   'token': token,
    		   'amount': amount,
    		   'currency': currency,
    		   'description': 'Your transaction description'}
    
    	request.post(
    	    //'https://sandbox.checkbook.io/api/v1/charge',
    	    'https://www.checkbook.io/api/v1/charge',
    	    { form: payload },
    	    function (error, response, body) {
    		if (!error && response.statusCode == 200) {
    		    console.log(body)
    		}
    	    }
    	);
    });
