I am trying to build a #PayPal checkout button in the #backend. The sample code they give uses express.js #NPM. Wix does not support it as they say that #httpfunctions does all that is needed from express.js
However, I have no idea how to convert the code to #httpfunctions. Here is my current code:
export function paypalRedirect() {
var express = require (‘express’);
var request = require (‘request’);
// Add your credentials:
// Add your client ID and secret
var CLIENT =
‘myclietID’;
var SECRET =
‘mySecret’;
var PAYPAL_API = ‘https://api.sandbox.paypal.com’;
express()
// Set up the payment:
// 1. Set up a URL to handle requests from the PayPal button
.post(‘/my-api/create-payment/’, function (req, res) {
// 2. Call /v1/payments/payment to set up the payment
request.post(PAYPAL_API + ‘/v1/payments/payment’, {
auth: {
user: CLIENT,
pass: SECRET
},
body: {
intent: ‘sale’,
payer: {
payment_method: ‘paypal’
},
transactions: [{
amount: {
total: ‘5.99’,
currency: ‘USD’
}
}],
redirect_urls: {
return_url: ‘https://example.com’,
cancel_url: ‘https://example.com’
}
},
json: true
}, function (err, response) {
if (err) {
console.error(err);
return res.sendStatus(500);
}
// 3. Return the payment ID to the client
res.json({
id: response.body.id
});
});
})
// Execute the payment:
// 1. Set up a URL to handle requests from the PayPal button.
.post(‘/my-api/execute-payment/’, function (req, res) {
// 2. Get the payment ID and the payer ID from the request body.
var paymentID = req.body.paymentID;
var payerID = req.body.payerID;
// 3. Call /v1/payments/payment/PAY-XXX/execute to finalize the payment.
request.post(PAYPAL_API + ‘/v1/payments/payment/’ + paymentID +
‘/execute’, {
auth: {
user: CLIENT,
pass: SECRET
},
body: {
payer_id: payerID,
transactions: [{
amount: {
total: ‘10.99’,
currency: ‘USD’
}
}]
},
json: true
},
function (err, response) {
if (err) {
console.error(err);
return res.sendStatus(500);
}
// 4. Return a success response to the client
res.json({
status: ‘success’
});
});
}).listen(3000, function () {
console.log(‘Server listening at http://forum.wixstudio.com/’);
});
}
