Payment Flow

Explore two flexible payment methods — one-time and recurring — to help businesses optimize user experience and automate revenue collection.

One-time Payment

The one-time payment flow allows customers to pay immediately for a specific order.

Detailed steps:

  1. Customer selects product: Adds to cart and clicks “Checkout”
  2. Website creates order: Stores order details in the database
  3. Generate checkout form: Prepare data and create HMAC-SHA256 signature
  4. Send request to SePay: POST form to /v1/checkout/init endpoint
  5. Validate signature: SePay verifies the signature validity
  6. Redirect customer: To SePay’s payment page
  7. Choose payment method: Card, QR Banking, or QR NAPAS
  8. Process payment: SePay communicates with the bank/card system
  9. Receive result: From the banking system
  10. Callback to website: Trigger corresponding callback URLs
  11. IPN notification: Notify payment result via IPN
  12. Redirect customer: Back to result page on your website
  13. Display result: Success / Failure / Canceled page

Recurring Payment
