We have put in a payment form on this page -

https://akashic-studies-australia.prod01.sydney.platformos.com/akashic-readings

There seems to be no way to put in the payment amount in the auto-responder, which is what client would need to acknowledge they have paid. They will of course also receive Stripe notification, but it would be good to be able to include this.
Or is the only alternative hardcoding it in with the content?
