Hello, I need help with paypal. I am using the paypal node integration(https://github.com/paypal/PayPal-node-SDK) with my express app and I can successfully get a payment from my code. Except there is a problem the total amount is hardcoded.
Here is my code:
const express = require('express');
const ejs = require('ejs');
const paypal = require('paypal-rest-sdk');
paypal.configure({
'mode': 'sandbox', //sandbox or live
'client_id': 'AaU8tQfmz1_MFDTKuf84yYERXvdDt2ZFJVrxhNW_49DazF4A_F0VBuKyV5_nntyEdZqUa5Oq9ZBj65GV',
'client_secret': 'EAZ8aFDU4lHHLy1bQqULYWqznf3dBknXZW3AH__zFC0bUs8AGUyR6RNbm-jHvqtikX7PsSqMO5vxuvKm'
});
const app = express();
app.set('view engine', 'ejs');
app.get('/', (req, res) => res.render('index'));
app.post('/pay', (req, res) => {
const create_payment_json = {
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://localhost:3000/success",
"cancel_url": "http://localhost:3000/cancel"
},
"transactions": [{
"item_list": {
"items": [{
"name": "Red Sox Hat",
"sku": "001",
"price": "25.00",
"currency": "USD",
"quantity": 1
}]
},
"amount": {
"currency": "USD",
"total": "25.00"
},
"description": "Hat for the best team ever"
}]
};
paypal.payment.create(create_payment_json, function (error, payment) {
if (error) {
throw error;
} else {
for(let i = 0;i < payment.links.length;i++){
if(payment.links[i].rel === 'approval_url'){
res.redirect(payment.links[i].href);
}
}
}
});
});
app.get('/success', (req, res) => {
const payerId = req.query.PayerID;
const paymentId = req.query.paymentId;
const execute_payment_json = {
"payer_id": payerId,
"transactions": [{
"amount": {
"currency": "USD",
"total": "25.00"
}
}]
};
paypal.payment.execute(paymentId, execute_payment_json, function (error, payment) {
if (error) {
console.log(error.response);
throw error;
} else {
console.log(JSON.stringify(payment));
res.send('Success');
}
});
});
app.get('/cancel', (req, res) => res.send('Cancelled'));
in the app.get('/success route') route, there is a constant
const execute_payment_json = {
"payer_id": payerId,
"transactions": [{
"amount": {
"currency": "USD",
"total": "25.00"
}
}]
}; My question is, How can I get the the total amount from app.post('/pay') in order to get the correct "total" amount.
