});
app.get('/success', (req, res)=>{
res.send("Success");
});
app.get('/failed', (req, res)=>{

async function addAccount(){
document.getElementById("accountDetails").innerHTML = "Wait for request to process"
await fetch(`${BACKEND_URL}/stripeConnectRegisterSeller`)
.then(res=>res.json())
.then(res => {
accountId = res.accountId;
const currentUser = Moralis.User.current();
currentUser.set("account_ID", accountId);
currentUser.save();
return res
})

console.log({paymentMethodType, amount, currency, userEthAddress, userStripeAccountId, tokenId, productType})
const session = await stripe.checkout.sessions.create({
payment_method_types: ['card'],
line_items: [{
name: "Connect",
amount: amount,

currency: currency,
}],
mode: 'payment',
success_url: 'https://example.com/success',

application_fee_amount: 0.03*amount,
transfer_data: {
destination: userStripeAccountId,

const makePayment = async ()=>{
const currentBid = document.querySelector('#payment-modal-token-price').value;
const userEthAddress = localStorage.getItem('userEthAddress');
const tokenId = parseInt(localStorage.getItem('tokenId'));
let productType = getProductType();
await fetch(
`${BACKEND_URL}/create-checkout-session`,
{
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
currency: 'inr',

userEthAddress: userEthAddress,
userStripeAccountId: 'acct_1K3HMxQkqeDnOAwK',
tokenId: tokenId,
tokenNos: 1,
productType: productType

}
)
.then((r) => r.json())
.then((res)=>{
const sessionId = res.session['id'];
var stripe = Stripe(STRIPE_PUBLISHABLE_KEY)
