Create external_account for Stripe Connect payouts with Stripe.js (iOS) - ios

Question

I am trying to connect actual bank accounts to the stripe accounts in Stripe Connect.
However, I am struggling with the actual implementation.
I use Custom Accounts, so I want to provide the user with the account creation logic through my iOS app.
In the Stripe API Reference it says that the recommended way to accomplish this is:
"Destination accounts are added via the external_accounts parameter when creating or updating Custom accounts. The value should be a bank account or debit card token returned from Stripe.js."
Creating the token is documented as follows (I am using NodeJS):
stripe.createToken('bank_account', {
country: 'US',
currency: 'usd',
routing_number: '110000000',
account_number: '000123456789',
account_holder_name: 'Jenny Rosen',
account_holder_type: 'individual',
}).then(function(result) {
// Handle result.error or result.token
});
Where to I link that token in the account creation process? See related code below:
app.post('/create_account', (req, res) => {
console.log('create account called');
var email = req.body.email;
var firstname = req.body.firstname;
var lastname = req.body.lastname;
stripe.accounts.create({
country: "CH",
type: "custom",
email: email,
business_name: "examplename",
legal_entity: {
first_name: "firstname",
last_name: "lastname",
dob: {
day: 1,
month: 1,
year: 1900
}
}
}).then((account) => {
res.status(200).send(account)
}).catch((err) => {
console.log(err, req.body)
res.status(500).end()
});
});
Is the token creation just a means of validating the account information client-side?
Would be glad if someone can elaborate on this with a simple step-by-step explanation, thank you in advance!

Answer 1

You'd pass the token in the external_account parameter:
var bankAccountToken = req.body.stripeToken;
stripe.accounts.create({
country: "CH",
type: "custom",
// ...
external_account: bankAccountToken,
}).then((account) => {
// ...
