Hi,
When someone tries to submit an ACY payment (if they already have an account) the stripe gateway only asks for an email address. It doesn't ask for any bank account information. Is there a reason it wouldn't show the bank account fields to input their information? Instead it is trying to use their old account, so there is no way to handle it other than manually cancelling it and then resubmitting their bank account info into Stripe manually. This defeats the purpose in the gateway entirely.

Please let me know if I'm missing anything? Thanks

Sorry I am not clear on this. It sounds like all that is being done is a wire transfer? Meaning if the user clicks pay & they see our account information (configured in stripe), then they have to still go and do a transfer from their bank, that is not an ach it is a wire transfer of sorts.
Typically an ACH would ask for the users account information and send a charge/deduct the funds from their bank account just like it does for a credit card.

Trying to understand that further...

Also we had a user input their email and click pay, it then told him thank you for the payment and displayed his old account number & routing number which was no longer open. So when I looked into stripe there was a pending ACH payment with the old source. I then had to put their account info into Stripe manually so we could verify their account and apply the charge.
Seems that it should be much smoother than that, no? For example, user selects the ACH option, they're asked for their bank account info and clicks pay. The pending status is sent to Stripe and they handle the transaction (takes a few days to verify and complete). This is how PayPal handles it also.
Thanks for further clarification, this was a large issue because the user didn't have the old account and yet it was still attempted to be processed.

Please see the following URL:
stripe.com/docs/ach

Stripe does allow ACH debits and they can be used just like a credit card, however they must be verified of course. The URL above explains this and how it is implemented. Please let me know, thank you!

While you're checking out the above please advise on this, the process in which this has occurred is extremely upsetting because it is a frustration for the user trying to make the payment.

We need to submit an API to stripe cancelling the ACH that was attempted via CBSubs because it is sitting in a pending state on stripe and it will not complete because the user doesn't have funds in that account as it is an old account. Due to the pending status of the ACH it doesn't allow us to set the new account as the default payment method.
I was told that we may need to submit an API to cancel the ACH so we can set the default to the updated account. Thanks
