The following describes the overall flow of how a successful payment integration would work when a payer enters your e-service to make a payment.
The payer accesses your e-service.
Your e-service initiates a payment on PaySG through a POST API call to the relevant endpoint to create a new payment. If necessary, your team can include a return_url which will be used to redirect users after successful payment. Please note that the return_url must be a valid HTTPS URL, otherwise, the payment creation will be blocked by PaySG.
The PaySG server returns a payment object to your e-service.
Your e-service then needs to redirect the payer to the payment_url, found in the payment object, which leads to PaySG's payment page.
The payer completes the payment on the PaySG payment page. Payment links will remain valid until cancelled on the dashboard/via API or when payment succeeds.
Upon successful payment, the PaySG payment page redirects the payer back to the return_url provided by your team. Please note that the return_url must be a valid HTTPS URL, otherwise, the payment creation will be blocked by PaySG.
The PaySG server responds by returning the payment status.
If the payment status is confirmed as paid, your e-service marks the payment as paid and allows the payer to continue with their e-service flow.
Send a GET request using the id and payment_service_id.
Your e-service receives the paysg_payment_id and paysg_payment_service_id and makes a GET API call to PaySG to verify the payment status. are also available.
Alternatively, set up a to receive updates of successful payments.
