Thanks, I don't see any request to update customer for this checkout session. Can you share with me your code?

proven pawn Apr 24, 2026, 5:07 AM

This is in my frontend for updating the session:
try {
await this.checkoutAction.runServerUpdate(() =>
this.invoiceService.updateCheckoutSession(
this.sessionId(),
'acct_123abc',
'cus_123,
invoice.livemode,
),
);
this.buttonRole.set('submitPayment');
} catch (error) {
console.error('Failed to update checkout session with customer details: ', error);
this.handleSecureError(error);
}
}

there is no error in this and working as expected and but as soon as i hit the confirm() i am getting email errror

And what's inside the this.invoiceService.updateCheckoutSession function ?

proven pawn Apr 24, 2026, 5:13 AM

#

it is api call to backend:
const updatedSession = await this.stripeService.updateCheckoutSession({
id: checkoutSessionId,
params: {
customer: 'cus_123'
},
requestOptions: { stripeAccount: stripeAccountId },
livemode,
});

#

req id:  req_gEwjwUNRlTAy1w```

#

I have called the update checkout session with customer id

woven wigeon Apr 24, 2026, 5:24 AM

That is still a wrapper. Can you show me the code that you call stripe api directly ?

proven pawn Apr 24, 2026, 5:25 AM

#

try {
            const stripeClient = new Stripe(environment.STRIPE.STRIPE_SECRET_KEY || '', {
              apiVersion: '2026-02-25.preview;' as any,
          });
            return await stripeClient.checkout.sessions.update(id, params, requestOptions);
        } catch (error) {
            this.handleStripeError(StripeService.name, error);
        }

Ok, thanks. And did you get any error from the api call?

proven pawn Apr 24, 2026, 5:28 AM

#

woven wigeon Apr 24, 2026, 5:36 AM

#

OK, did you run https://docs.corp.stripe.com/js/custom_checkout/run_server_update to sync the chekcout session after the update?

woven wigeon Apr 24, 2026, 5:49 AM

#

Ok, I just realized you haven't set an email to the customer, can you set an email to it and try again>

proven pawn Apr 24, 2026, 5:56 AM

#

i am creating it before the updating the checkout session:
const newCustomer: any = {
email: customerEmail,
description: customerEmail + ' | ' + customerName,
}
const createdCustomer = await this.stripeService.createCustomer({
params: newCustomer,
requestOptions: { stripeAccount: stripeAccountId },
});
and then i have attached the customer id received from above call to update checkout session,

woven wigeon Apr 24, 2026, 5:58 AM

#

Can you check the value of customerEmail ? is it emtpy or null?

proven pawn Apr 24, 2026, 6:00 AM

#

Ahh, there you go, I just released that, it is empty string. but why i did not get any error in update checkout session call, i am seeing in dashboard the update call is going success.

woven wigeon Apr 24, 2026, 6:02 AM

#

Checkout will only validate the customer email when you confirm the checkout session.

proven pawn Apr 24, 2026, 6:04 AM

#

Okay, maybe i should get better at debugging, thanks a lot.
