Let us understand the building blocks that are required to build a configuration of your choice:

Payment Methods

Before deciding the payment methods or payment instruments that you want to configure on the Checkout, refer to the

payment methods

supported by Curlec.

Payment Instruments

A payment instrument is a combination of the payment method and its associated properties. For example, a payment instrument can be an RHB Debit card, where card is the payment method and the issuer (RHBB bank) is the associated instrument.

An instrument is a JSON object with a key named method. Each method and its associated properties are described in the sections below:

Card

Payment instruments for the method: card are listed below:

name	type	description	values	examples
issuers	array	List of issuers that are allowed	Any bank code	issuers: ["CIBB", "RHBB"]
networks	array	List networks that are allowed	Any card network	`networks: ["Visa", "MasterCard"]`
types	array	List of card types that are allowed	Any card type	`types: ["credit"]`

// beginning of the code
....
card: { \\name for cards
    name: "Pay Via Cards"
    instruments: [
      {
        method: "card",
        issuers: ["HSBC"],
        networks: ["MasterCard"],
        types: ["debit","credit"]
      }
    ]
},
...
//rest of the code

FPX/Online Banking

Payment instruments for the method: fpx are listed below:

name	type	description	values	examples
banks	array `<string>`	List of all banks that are allowed	Any bank code	`banks: ["CIBB", "RHBB"]`

Wallet

Payment instruments for the method: wallet are listed below:

name	type	description	values	examples
wallets	string	Wallets to be allowed	Any wallet code	`wallets: ["grabpay", "touchngo"]`

Blocks

A block is a collection of one or more payment instruments. Each block has a name and code associated as shown below:

// Block creation
let myPayments = {
  name: "My Custom Block",
  instruments: ["grabpay", "touchngo"]
};
// Usage in config
let config = {
  display: {
    block: {
      highlighted: myPayments
    }
  }
};

Here, highlighted is the code associated with myPayments. Multiple blocks can be added to the config at the same time.

Sequence

You can specify the sequence, that is the order, in which the payment methods should be displayed on the Checkout.

A sequence is an array of strings, where each string is the name of the payment method or a block.

In a sequence, you can include any block using the block.${code} format. The block with code highlighted should be represented as block.highlighted as shown below:

let sequence = ["block.highlighted", "fpx", "wallet"];

The above sequence will place the code highlighted first followed by the payment methods fpx and wallet in that particular order.

Handy Tips

Every block defined has to be present in the sequence. If you do not wish to reorder the methods and want to place your block, the sequence should contain block.highlighted with just one item in it.

Preferences

Using the preferences object, you can enhance the configuration of the Checkout. By setting this value, you can decide whether the default list of payment methods should be displayed or not.

Possible values are:

true

Checkout will display the sequence of the payment methods configured by you alongside with the default order of payment methods available in the Checkout.

false

Checkout will only show the sequence of the payment methods configured by you.

Hide Payment Instruments

You can also hide or remove certain instruments from the Checkout.

This is an array containing the method key used to hide either the payment method and/or the payment instrument associated with that payment method. For example, you can hide the methods, card and wallets on the Checkout.

let cardInstrument = {
  method: "card"
};

let instrumentOfSomeBank = {
  method: "fpx",
  banks: ["RHBB"]
};

let hiddenInstruments = [cardInstrument, instrumentOfSomeBank];

Handy Tips

Hiding any instrument using hide does not affect the similar instrument defined in blocks. So, if you want to hide RHBB bank from FPX/Online Banking and have defined the same instrument in one of your blocks, Axis bank will still be displayed in that block.
