Example
Say the payment URL for a client is https://demo.snapbill.com/payment/client/FoE:A/GIQ56fGwX05z. After adding an invoice for the client through the API, you can redirect them to https://demo.com/success/FoE:A by sending the client to https://demo.snapbill.com/payment/client/FoE:A/GIQ56fGwX05z?redirect=https%3A%2F%2Fdemo.com%2Fsuccess%2FFoE%3AA.
An example of the variables POSTed to the redirect URL is below:
[payment_amount] => 476
[payment_id] => 30
[payment_method_code] => payfast
[payment_state] => pending
[redirect] => https://demo.com/success/FoE:A
[success-heading] => Your payment has been processed
[success-message] => Your payment is marked as pending. We are still awaiting confirmation from PayFast, but as soon as that is received your invoices will be marked as paid.
[transaction_uuid] => OWI0ZWU3ZTktYTNkYi00NGYyLWEzZWEtZWZhOWVmMzRlZGQx
[signature] => yynYkjNvYyrMnS1wmItMa5pZhyEjtirgRM1UZ6fN6a0=
In the case of a payment method which requires you to process the payment, the variables passed back won't include the payment:
[payment_method_code] => other
[redirect] => https://demo.com/success/FoE:A
[success-heading] => Your payment details have been updated
[success-message] => Thank you for updating your payment details
[transaction_uuid] => MTA1OGRhNTItMTZlYi00YWI1LWFiMjgtNjJlMTU0N2Y3Yjc1
[signature] => dUOawxjoHyzg9xq9t2ZCcaspIbkEVpqPKKJnqkkdTWY=
