Send a branded receipt the moment a Paystack payment succeeds.
In your Paystack dashboard, point the webhook at an endpoint on your server and verify the Paystack signature.
When a charge.success event arrives, POST to https://mail.axene.io/v1/emails/ with the customer details to send the receipt.
Keep the receipt as an Axene template so finance can edit the copy without touching code.
A no-code Paystack recipe that maps events to templates without a server is on the roadmap.
