When you're setting up a store or updating payment settings, you can place a test order to ensure the checkout is functioning as expected.
Have you been experiencing issues with the checkout on your store? If you ran into an error message while testing payments, have received reports from customers, or see any error messages when viewing payment events under Orders > Abandoned checkouts, please let me know and I'd be happy to provide some more information based on specific error messages.
Thank you for getting back to me. We received reports from our customers that they were unable to complete the purchase, the system won't accept the payment. Please advise.
Attached are sample emails from customers reporting the issue.
I appreciate you following up with these customer reports.
I see that one customer mentioned the checkout was loading indefinitely when they attempted to pay. In that case, there may have been a local network issue on their end. It looks like the other customer left the chat without providing any information on what they experienced, so we'll need more information on what happened at the checkout in order to find a resolution.
What do you see when you view the payment events under Orders > Abandoned checkouts in the admin? The History section on each abandoned checkout will provide specific error messages if a payment was attempted, and that will give us some insight into what happened in these cases.
Let me know which payment methods these customers attempted and whether there are any error messages associated with their abandoned checkouts.
