Hi

My idea is to charge the customer directly in our app when we have the cards on file.
You can follow this guide for this:
https://stripe.com/docs/payments/save-during-payment
This isn't using Checkout Session, because this use case is quiet advanced. You need more customizable integration using Stripe Elements for that.
Does our back-end receive the errors?
You can set up webhooks for that and listen for payment_intent.payment_failed
https://stripe.com/docs/api/events/types#event_types-payment_intent.payment_failed

[hollow meadow]

so if I understand we will receive the error from Stripe and we can visualize it to the customer?

And does the customer receives a notification from Stripe (email etc..) for failed payment attempt

[delicate osprey]

Your backend can receive a notification (webhook event) yes, you can show the customer the error from the frontend too

[delicate osprey]

no

[hollow meadow]

does the stripe support if contacted by the customer can provide the reasons for the failed attempt?

[delicate osprey]

They need to reach out to you first.

[hollow meadow]

and our support can contact yours?

in case we have some issues in the backend?

[delicate osprey]

Yes of course, don't hesitate to come back if you have issue in your integration.
