How do I make a http post request in Node based off of a curl request?

Question

Paypal says to make the following curl request

  curl -v POST https://api-m.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "CLIENT_ID:SECRET" \
  -d "grant_type=client_credentials"

However, I want to instead do that through an HTTP request. I tried the following:

const HTTP = require('http')
const data = JSON.stringify({
    paypalclientid:paypalsecretid,
    "grant_type": "client_credentials",
})
const options = {
    host: 'api-m.sandbox.paypal.com',
    port: 80,
    path: '/v1/oauth2/token',
    method: 'POST',
    headers: {
        'Accept': 'application/json',
        "Accept-Language": "en_US"
    }
}
const req = http.request(options, res => {
    console.log(`statusCode: ${res.statusCode}`)

    res.on('data', d => {
        process.stdout.write(d)
    })
})

req.on('error', error => {
    console.error(error)
})

req.write(data)
req.end()

and I got the following:

<HTML><HEAD>
<TITLE>Access Denied</TITLE>
</HEAD><BODY>
<H1>Access Denied</H1>
 
You don't have permission to access "http&#58;&#47;&#47;api&#45;m&#46;sandbox&#46;paypal&#46;com&#47;v1&#47;oauth2&#47;token" on this server.<P>
Reference&#32;&#35;18&#46;9ce33e17&#46;1609625956&#46;708d702f
</BODY>
</HTML>

That is what you get when you do a normal GET request.

Answer 1

You need to base64 encode your credentials and send them along in an Authorization header.
You need to make the request over https.
You need to form encode the content.

Here's an example that works with a valid user and pass :

 const https = require('https') const data = `grant_type=client_credentials`; const user = 'your client id'; const pass = 'your secret'; const authorization = `Basic ` + Buffer.from(`${user}:${pass}`).toString(`base64`); const options = { hostname: 'api.paypal.com', port: 443, path: '/v1/oauth2/token', method: 'POST', headers: { 'Authorization': authorization, 'Content-Type': 'application/x-www-form-urlencoded', 'Content-Length': data.length }, } const req = https.request(options, res => { console.log(`statusCode: ${res.statusCode}`) res.on('data', d => { process.stdout.write(d) }) }) req.on('error', error => { console.error(error) }) req.write(data) req.end()

Answer 2

Seems you need basic authentication :

const options = {
    auth: 'CLIENT_ID:SECRET',
    ...

You should also be using port 443 (HTTPS), as well as:

    'Content-Type': 'application/x-www-form-urlencoded'

for this particular token request (almost all other PayPal REST endpoints take application/json )
