# FPX Online Banking Malaysia for API only

Add FPX Online Banking Malaysia to your API-only integration.

[View source](/payment-methods/fpx-online-banking-malaysia/api-only.md)

You can add FPX Online Banking Malaysia to your existing integration. The following instructions show only what you must add to your integration specifically for FPX Online Banking Malaysia.

If an instruction on this page corresponds with a step in the main integration guide, it includes a link to corresponding step of the main integration guide.

## Requirements

| Requirement           | Description                                                                                                                                                                                                                |   |
| --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type**  | Make sure that you have an existing [API-only integration](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only).                                                                   |   |
| **Redirect handling** | Make sure that your existing integration is set up to [handle the redirect](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#handle-the-redirect). `action.type`: **redirect**. |   |
| **Setup steps**       | Before you begin, [add FPX Online Banking Malaysia in your Customer Area](/payment-methods/add-payment-methods).                                                                                                           |   |

## How it works

1. The shopper selects FPX Online Banking Malaysia as the payment method.
2. The shopper enters their details in the [payment form that you build](#build-your-payment-form).
3. When you make the payment request, you [include additional information about the items that the shopper intends to purchase](#additional-parameters-payments).
4. Your existing integration setup will [handle the redirect](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#handle-the-redirect).

## Build your payment form

To show FPX Online banking 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. All issuers in this list must be included on your checkout to be compliant with PayNet local regulations.

   | Bank name               | Issuer ID       |
   | ----------------------- | --------------- |
   | Affin Bank              | fpx\_abb        |
   | Agro Bank               | fpx\_agrobank   |
   | Alliance Bank           | fpx\_abmb       |
   | Am Bank                 | fpx\_amb        |
   | Bank Islam              | fpx\_bimb       |
   | Bank Muamalat           | fpx\_bmmb       |
   | Bank Rakyat             | fpx\_bkrm       |
   | Bank Simpanan Nasional  | fpx\_bsn        |
   | CIMB Bank               | fpx\_cimbclicks |
   | Hong Leong Bank         | fpx\_hlb        |
   | HSBC Bank               | fpx\_hsbc       |
   | Kuwait Finance House    | fpx\_kfh        |
   | Maybank                 | fpx\_mb2u       |
   | OCBC Bank               | fpx\_ocbc       |
   | Public Bank             | fpx\_pbb        |
   | RHB Bank                | fpx\_rhb        |
   | Standard Chartered Bank | fpx\_scb        |
   | UOB Bank                | fpx\_uob        |

The list of issuing banks are also included in the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) response object `type`: **molpay\_ebanking\_fpx\_MY**

You can [download the logo for Razer Merchant Services and the issuing banks](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%2Bonly\&version=71#downloading-logos) to use in your form.

## Get FPX Online Banking Malaysia as an available payment method

}
```

## Test and go live

Using any issuer ID that is available for the Online banking Malaysia Component for the respective country/region, make Online banking Malaysia online banking test payments to test the different payment results.

Check the status of the Online banking Malaysia test payments in your [Customer Area](https://ca-test.adyen.com/) > **Transactions** > **Payments**.

Before you can accept live Online banking Malaysia payments, you need to [submit a request for Online banking Malaysia](/payment-methods/add-payment-methods) in your [live Customer Area](https://ca-live.adyen.com/).
