I am trying to create a payment option for a customer's website. All they need to capture is a single field from the payer (Customer ID, which the customer will key in when making a payment) in order to know who to apply the payment to internally and nothing else. I am trying to find the most fuss-free way to achieve this.
I was told by your phone support that I can just add a field to the Payment Page, like Refrence/Order #, rename it to what I need it to be and just place the Pay Now button on the website. This doesn't seem to work because from what I understand via the docs, those custom fields are read-only, and can only display data that is passed to the Payeezy form from the merchant website, with no option for editing the contents any more. I also tried using the Address field for this, but that doesn't seem to be displayed anywhere on the transaction details once it goes through, so it's of no use.
So my question is this: is there a way to include a visible custom field into the form we're submitting (the Pay Now button is a form itself), and if so what is the correct way to do that so the value of it is visible to us in the transaction details. Or is it absolutely necessary to save this info locally and then redirect the customer to Payeezy after that?
