Missing Stripe Connect Custom Account Information for Node.js - node.js

Question

Currently working on server side info for Stripe connect and I'm having issues figuring out the correct parameters for creating a stripe connect account. I'm stuck on tax_id (ein) at the moment. Can someone please give me the correct abbreviation for this any others I may be missing on Node.js.
For example when it came to the name of the business Stripes API just say "name". Yet I kept getting the error 'Received unknown parameters: name'. But after some help looking online I saw that the correct way was to write out 'business_name' even through this was no where in the Stripe API.
here is my code: Hope this helps guide some people in the right direction as well (:
app.post('/newConnectCompanyAcct', (req, res) => {
// Creating New Connect Account...
//User
var company = req.body.business_name
var ein = req.body.business_tax_id
var first = req.body.first_name
var last = req.body.last_name
var email = req.body.email
var phone = req.body.phone
var birthDay = req.body.birthDay
var birthMonth = req.body.birthMonth
var birthYear = req.body.birthYear
var ssn = req.body.personal_id_number
var time = req.body.Time
var ip = req.body.iP
//Acct Type
var type = req.body.type
//Address
var line1 = req.body.line1
var line2 = req.body.line2
var zipcode = req.body.postal_code
var city = req.body.city
var state = req.body.state
var lastFour = req.body.lastFour
console.log('the email ' + email);
console.log('the phone ' + phone);
