Online banking Thailand for API only

Add Online banking Thailand to an existing API-only integration.

Accept Online banking Thailand payments using our APIs, and build your own payment form to have full control over the look and feel of your checkout page.

Before you begin

Before starting your Online banking Thailand integration:

  1. Make sure you have set up your back end implementation.
  2. Add Online banking Thailand in your test Customer Area.

Build your payment form for Online banking Thailand

To show Online banking Thailand in your payment form, you need to:

  1. Show a list of available banks to your shopper.
  2. After the shopper selects a bank, pass the corresponding Issuer value to your server. You'll need this to make a payment.
Bank name Issuer ID
Bangkok Bank molpay_bangkokbank
Krungsri Bank molpay_krungsribank
Krung Thai Bank molpay_krungthaibank
The Siam Commercial Bank molpay_siamcommercialbank
Kasikorn Bank molpay_kbank

We provide logos for Razer Merchant Services and the issuing banks, which you can use on your payment form. For more information, refer to Downloading logos.

You can also get the issuer list from the /paymentMethods response, as explained in the API-only integration guide.

In your /paymentMethods request, specify:

The list of issuing banks are included in the object with type: molpay_ebanking_TH.

Make a payment

In your /payments request, specify:

  • paymentMethod.type: molpay_ebanking_TH.
  • paymentMethod.issuer: The shopper's bank. In this example, the issuer is set to Bangkok Bank. Specify this with the Issuer value that corresponds to this bank.
  • returnUrl: The URL where the shopper will be redirected back to after they complete the payment.

In the /payments response, note the action object. This contains the information needed to redirect the shopper.

Handle the redirect

  1. To complete the payment, redirect the shopper to the action.url returned in the /payments response.

    When using the HTTP GET method:
    For security reasons, when displaying the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView.

  2. After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:

    • details: object that contains the URL-decoded redirectResult returned when the shopper was redirected back to your site.
  3. In the response note the following:

    • resultCode: use this to present the result to your shopper.
    • pspReference: our unique identifier for the transaction.

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for Online banking Thailand are:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment has been successful.
You will receive the funds in 2-3 days.
Cancelled The shopper cancelled the payment while on their bank's website. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error There was an error when the payment was being processed. Inform the shopper that there was an error processing their payment. You'll receive a refusalReason in the same response, indicating the cause of the error.
Pending or
Received
The shopper has completed the payment but the final result is not yet known. It may take minutes or hours for the MOLPay online banking payments network to confirm this. Inform the shopper that you've received their order, and are waiting for the payment to be completed.
You will receive the final result of the payment in an AUTHORISATION webhook.
Refused The payment was refused by the shopper's bank. Ask the shopper to try the payment again using a different payment method.

If the shopper failed to return to your website or app, wait for webhooks to know the outcome of the payment:

eventCode success field Description Action to take
AUTHORISATION false The transaction failed. Cancel the order and inform the shopper that the payment failed.
AUTHORISATION true The shopper successfully completed the payment. Inform the shopper that the payment has been successful and proceed with the order.
