I have asked this question before, but the ticket was closed and no resolution or solution was reached.

I am not able to make a purchase using the Stripe payment method. I have verified with Stripe and my bank that everything is setup correctly except for one thing. I will include what they said below. They asked us to add something that I can't find a place to add from the settings and I need help knowing where to put it or if there is something else I have overlooked in the setup process.

Stripe Support Response: "We have noticed that your live mode Stripe integration is experiencing errors because you're not providing a return_url in your Payment Intent.

The return_url is the URL that your customer is directed to once they have completed their payment. As of version 2023-08-16 of the API, we now require that a return_url is provided upon Payment Intent confirmation. We recommend updating your code to reflect this change and to prevent any further errors."

I have attempted to resolve it by reconfiguring Stripe integration with new keys, but this did not change anything.

Can you please tell me where to include the return_url in the Payment Intent?

I will send a private response with access details.

Okay, this issues is also resolved. I guess the problem was on my CREDIT Card, because a different DEBIT card worked.

Thank you for responding. I don’t know why the first card was not working with Stripe as it works everywhere else, even on other sites stripe. This is why I was confused. 

Anyway, this ticket can also be closed. We completed a test purchase and it notified the site owner.
