Send Post request in Node js Rest API - node.js

Question

I CAN'T SEND POST REQUEST FROM CLIENT SIDE !
I need to send HTTP Post request in Node js Rest API to the payment gateway.
Post request needs to have headers and body payload. I have frontend and backend separated, I'm using Rest API with express.js and payment gateway needs server to server communication so I can't to do that from client side. Basically when user clicks on payment I need to send call to my backend server then my backend server needs to send request to the payment gateway.
Payment gateway has documentation with only MVC ( Model View Controller ) and they really can't help.
So logic inside controller should be something like this
exports.payment = (req, res, next) => {
const { amount, id, currency } = req.body;
//add headers
//create body paloyad
//send request to https://payment....com/api-key/transaction
//receive response
res.status(200).json({ status: 'success' });
}

There are several ways to do it, like Fetch, however, I prefer using Axios:
const axios = require('axios');
exports.payment = (req, res, next) => {
const { amount, id, currency } = req.body;
//add headers
const options = {
headers: {'X-Custom-Header': 'value'}
};
//create body payload
const body = {
amount: amount
id: id
currency: currency
};
//send request to https://payment....com/api-key/transaction
axios.post('https://payment....com/api-key/transaction', body, options)
.then((response) => {
//receive response
console.log(response);
res.status(200).json({ status: 'success' });
})
.catch((error) => {
console.log(error)
});

Use Axios to send POST requests. Its much easier.
const axios = require('axios')
let config = {
headers: {
header1: value,
}
}
let data = {
'amount': amount,
'id':id,
'currency':currency,
}
axios.post('https://payment....com/api-key/transaction', data,config)
.then(function (response) {
console.log(response);
})

You can use https://github.com/node-fetch/node-fetch
const fetch = require('node-fetch');
const body = {a: 1};
const response = await fetch('https://httpbin.org/post', {
method: 'post',
body: JSON.stringify(body),
headers: {'Content-Type': 'application/json'}
});
const data = await response.json();
console.log(data);
